These technical conditions of multi-apartment buildings are a huge digital array for making important management decisions both within the boundaries of individual territories of the municipality, and for planning budget expenditures within the municipality, the subject of the federation and the country as a whole. Aspects of the formation of data on apartment buildings in various information systems are considered. The basics of ensuring the reliability of the presented data are considered. It is noted in the work that for many years, during the transition from a planned economy to a market economy, the requirements of technical regulations and normative documents for the maintenance and operation of apartment buildings are not fully complied with by the operating organizations. The deadlines for replacing systems and equipment that have worked out the deadline are not met. It is noted that federal legislators and the Government of the Russian Federation have not determined a general procedure for monitoring the technical condition of apartment buildings and have not formed a general approach to assessing their technical condition, the obligation of owners of premises of apartment buildings to finance these works, their frequency has not been determined. It was revealed that the data obtained during the monitoring of the technical condition of apartment buildings combined in federal and regional information systems would be an objective marker in the formation of state and municipal programs in the field of reducing the housing stock unsuitable for living. financing of monitoring.

Robust, resilient, agile and improvisatory styles in policymaking: the social organisation of anomaly, risk and policy decay
Authors: 6 Perri
Published: January 2022

This theory development article employs neo-Durkheimian institutional theory to present a fresh understanding of policy styles in the policy process. Calls for resilient, robust, agile and improvisatory policymaking are not readily compatible with each other. Each of these styles carries risks and each generates anomalies. Each tends to decay over time. Governments should therefore expect risks of inconsistency and decay in policymaking shaped by these styles. The article argues that these styles, and their risks and tensions, and the trajectories of their decay all arise from the contrasting forms of informal social organisation among policymakers in which they are cultivated. These forms of social organisation give rise to distinct types of bounded rationality, which shape decision-making differently in each ordering.
How can non-elected representatives secure democratic representation?
Authors: Fossheim Karin
Published: January 2022

Research on the democratic legitimacy of non-elected actors influencing policy while acting as representatives is often lacking in governance literature, despite being increasingly relevant worldwide. Recent theories of representation argue that there are non-electoral mechanisms to appoint such non-elected representatives and hold them responsible for their actions. Consequently, democratic non-electoral representation can be achieved. Through empirical analysis, this article explores democratic non-electoral representation in governance networks by comparing how non-elected representatives, their constituents and the decision-making audience understand the outcome of representation to benefit the constituency, authorisation and accountability. The research findings conclude that all three groups mostly share the understanding of democratic non-electoral representation as ongoing interactions between representatives and constituents, multiple (if any) organisational and discursive sources of authorisation and deliberative aspects of accountability. All of these are non-electoral mechanisms that secure democratic representation. These findings make an important contribution to the literature on non-electoral representation in policymaking.

DC hardcore, gentrification and punk urbanism
Authors: Woods Maxwell
Published: January 2022

This article examines the narratives that enabled and legitimized the gentrification of several neighbourhoods of Washington DC during the 1980s. What links each of the neighbourhoods (Georgetown, Mt. Pleasant, Adams Morgan, sections of the U Street/Shaw neighbourhood and parts of Penn Quarter) is that all experienced gentrification after the arrival of punk communities to their spaces in the early 1980s. I argue that DC punk urbanism is tied to a process through which middle- and upper-class suburban youth valorize neighbourhoods marked by urban decay and disinvestment, occupy those spaces without putting themselves into relation with already existing subaltern urbanisms and subsequently replace the neighbourhood fabrics of the residents who formerly lived there with their own.

Published: January 2022

The growing trend of the urban population looks for the formation of the concept of Smart Cities, based on the principles of sustainable development, which will meet the needs of people who live in them. The city must develop its public service infrastructure to provide all the requirements for the population. One of the requirements, people living in cities is the security of public areas managed by the city. The system of video surveillance, public areas should contribute to the personal safety of citizens, children and traffic, reducing the rate of crime and more efficient operation of public services. This research aims to examine academics' opinions (perceptions) about the impact of security cameras on increasing security within the concept of Smart Cities. The research had conducted on the territory of Serbia through an online survey. The obtained data were processed statistically by Chi-square and T-test, ANOVA method, multiple regression and correlation using SPSS application. The research indicates that academics much more believe in the contribution of video surveillance, reducing the crime rate, than studies of the effectiveness of the use of video surveillance shows. Video camera monitoring accelerates the reactions of competent services, but video camera recordings have not always been accepted as evidence in court.

Authors: Paun Cristian , Musetescu Radu , Isaic Radu , Manea Gheorghe Cosmin , Shayb Hezi
Published: January 2022

Modern economies are disturbed by recessions that became more and more globalized, much contagious between countries and regions and with higher negative impact during recessions. In this dynamic context, the recovery after recession is essential to prepare the economy for the next business cycle. Understanding of these business cycles (their causes and impact) is fundamental for public policies that should avoid to be pro-cyclical and to add more vulnerabilities to the existing ones. The economic resilience is now a key concept and refers to the capacity of the economy to recover after any recession. The aim of this paper was to explore the relationship between the dimension of the state and the resilience of the economic system by using a global panel data. The study includes 87 countries (870 observations) and data covering 2009 – 2019 provided by World Bank. We used 2 depending variables: GDP gap and GDP per capita gap and 12 explanatory variables grouped in 4 categories: dimension of the state, the quality of public governance, economic development and regional/global economic dependence). The results are robust and significant, confirming that the dimension of the public intervention and the quality of the public governance & administration have a clear impact on the economic resilience and recovery between business cycles.
Exploring and visualizing spatial effects and patterns in ride-sourcing trip demand and characteristics
Authors: Kelleny Bishoy , Ishak Sherif
Published: January 2022

The complex demand pattern of ride-sourcing remains to be a challenge to transportation modeling practitioners due to the infancy and the inherently dynamic nature of the ride-sourcing system. Spatial effects exploration and analysis protocols can provide informative insights on the underlying structure of demand and trip characteristics. Those protocols can be thought of as an opportunistic strategy to alleviate the complexity and help specifying the appropriate econometric models for the system. Spatial effects exploration is comparable to point pattern analysis, in which, signals from spatial entities, like census tracts, can be analyzed statistically to reveal whether a specific phenomenon respective signal distribution is a completely random process or if it follows some regular pattern. The results of such analysis help to explore the investigated phenomenon and conceptualize its causal forces. In this paper, we apply spatial pattern analysis edge methods integrated into a visual analytics framework to: (1) test the null hypothesis of system demand complete randomness; (2) further analyze and explain this demand in terms of the origin-destination (OD) flow and trips characteristics, i.e., length and duration; and (3) develop a pattern profile of the demand and trip characteristics to provide potential directions to modeling and predictive analytics approaches. This framework helps explain the ride-sourcing system demand and trip characteristics in space and time to fill the gap in integrating the system in multimodal transportation frameworks. We use the ride-sourcing trip dataset released from the City of Chicago, USA, for the year 2019 to showcase the proposed methods and their novelty in capturing such effects as well as explaining the underlying complexities in a streamlined workflow. The ride-sourcing demand hotspots were explored and identified in the city’s central business district. A novel method to capture and analyze the origin-destination flowlines was developed and implemented. Finally, a complementary trip characteristics pattern analysis was conducted to fully comprehend the system and validate the findings from the system demand points and OD-flowlines.
Investigating trends and characteristics of animal-vehicle crashes in Wyoming
Authors: Roy Uttara , Ksaibati Khaled
Published: January 2022

Animal-vehicle crashes (AVCs) are a severe concern in the United States as well as in Wyoming. This study investigated the current trends of AVCs and crash rate per vehicle miles traveled (VMT) for the State of Wyoming using police-reported crash data for ten years collected from the Wyoming Department of Transportation (WYDOT). The study also examined different driver, vehicular, roadway, and environmental conditions related factors that had a strong association with AVCs. The logistic regression model was developed to check how the factors prevalent in AVCs influence the severity of AVCs. The results showed that the percentage of AVCs to that of total crashes ranged from around 15% to 22%. Among different animals involved in crashes, the majority were deer. AVCs were found to have two peaks: dawn and dusk. AVC rate was found to be the highest in November. Also, dark and unlit conditions had a strong association with AVCs. Most of the AVCs tended to occur when there were no adverse weather conditions. When the speed limit was examined, it was found that the AVC crash rate tended to increase when the posted speed limit was higher than 60 mph. AVC rate was also higher when the road surface condition was dry. Higher posted speed limit, younger drivers, and dry road surface were also found to increase the severity of AVCs. The results identified in this study will be helpful to identify effective countermeasures to reduce AVCs in Wyoming.
Trend analysis of the productivity of Nigerian seaports
Authors: Nze Obiageli N. , Okeudo Geraldine N. , Ejem Ejem Agwu
Published: January 2022

This paper assessed the trend of productivity of the existing six Nigerian ports. Secondary data was extracted from National Bureau of Statistics (NBS) Annual Reports, Nigeria Port Authority (NPA) Annual Reports, and Central Bank of Nigeria (CBN) Annual reports. Using the Data Envelopment Analysis technique, it was discovered that Calabar Port had been under-utilized towards the achievement of the required results. On the contrary, Rivers Port requires technical touches in her operations. As a liquid bulk port, the time of loading and discharging of commodities are often more than any other type of port and the turnaround time at this port are often more. Scale optimization is also required in Rivers Port. Inferentially, Lagos Port has been operating on optimal scale size but fluctuating managerial efficiency was experienced in the operation years. As a matter of findings, Tin Can Island has a similar trend to that of Onne Port with low productivities in the pre-concession period which improved consistently in the post-concession year of 2010 till the year 2015. It was also observed that Tin Can Island Port operated on under-utilization of inputs resources in the pre-concession periods till the post-concession year 2010. This reflects the element of wastefulness concerning both inputs and outputs quantities. Delta Port experienced fluctuating scale and technical efficiency trends in both pre and post concession years. Hence, it is observed that productivities' trends vary among the concessioned Nigerian Ports. These could be as a result of the influence of varied exogenous and endogenous factors on individual Port.

Published: January 2022

The rising occurrence of infections generated by Escherichia coli and Klebsiella pneumoniae that produce extended-spectrum β-lactamase (ESBL) is reason for concern. Due to the recent emergence of multidrug-resistant microorganisms that develop ESBL. The purpose of this work was to detect the ESBLs in clinical isolates of E. coli and K. pneumoniae. 118 samples of E. coli and 63 isolates of K. pneumoniae were collected from clinical samples. Polymerase chain reaction was used to detect β-lactamase genes (i.e., blaTEM, blaSHV, and blaCTX-M). Phenotypic detection revealed that 48.31% and 85.19% of E. coli and K. pneumoniae produced ESBLs, respectively. Whereas screening of ESBL genes in both bacteria employing a multiplex PCR test revealed that 24.58% of the ESBL-producing E. coli strains contained blaTEM, 50.85% contained blaSHV, and 32.2% contained blaCTX-M. Nevertheless, in K. pneumoniae, 40.74% blaTEM, 35.19% blaSHV, and 64.81% blaCTX-M genes were present. Antimicrobial resistance profiles of E. coli and K. pneumoniae isolates to twenty antibiotics were observed to vary significantly. Additionally, it was determined that the majority of E. coli and K. pneumoniae isolates were multidrug resistant (MDR). Additionally, 80.51% of E. coli isolates were resistant to the AMC antibiotic, while 0.00% were resistant to IPM and MEM. From the other hand, the resistant proportion of K. pneumoniae isolates was heterogeneous, ranging from 69.84% against CAZ to 0.00% against CIP and G antibiotics. The blaSHV gene was the most widespread among different forms of ESBLs in E. coli, but the most common gene in K. pneumoniae isolates was blaCTX-M (64.81%).

Expression of CDK9 in endometrial cancer tissues and its effect on the proliferation of HEC-1B
Authors: Yang Wen , Liu Shaoyan , Luo Qiuping , Tan Xuexian
Published: January 2022

Endometrial cancer (EC) is one of the most common malignant tumors in the female reproductive system, which has been threatening the life and health of many women. Its incidence and mortality rate remain high, resulting in a low survival rate. In this study, the expression of cyclin-dependent kinase 9 (CDK9) in EC tissues was investigated, and its effect on the proliferation of EC cell line HEC-1B was preliminarily analyzed. RT-qPCR and Western blotting showed that CDK9 mRNA and protein were significantly reduced in the small interfering (si)RNA interference group compared with the siRNA control and blank control groups. MTT assay showed that the EC cell proliferative ability was significantly decreased, and phosphorylated-phosphatidylinositol 3 kinase (p-PI3K)/PI3K and phosphorylated-protein kinase B (p-AKT)/AKT were significantly reduced in the siRNA interference group compared with the siRNA control and blank control groups. In conclusion, the high expression of CDK9 is a factor of poor prognosis in EC, and the reduction of CDK9 can inhibit HEC-1B cell proliferation, which may be related to the inhibition on the activation of the PI3K/AKT signaling pathway.
A corpus-based study of the ADJ-looking adjectivization in English
Authors: Guo Man , He Qingshun
Published: January 2022

This article aims to conduct a corpus-based study of the diachronic and synchronic distributions of a special type of participle adjectivization, the ADJ-looking adjectivization. The study based on the Corpus of Historical American English (COHA) finds that this process of adjectivization consists of two phases: (1) The downward rank-shift from the look ADJ construction to the ADJ looking adjectivization is a process of metaphorization; (2) The transcategorization from the ADJ looking adjectivization to the ADJ-looking adjectivization is a process of lexicalization. The study based on the Corpus of Contemporary American English (COCA) finds that ADJ-looking adjectivizations are mode and register sensitive but not discipline sensitive. The modifier use prefers to occur more in hard science texts to increase the complexity of nominal groups and the predicative use prefers to occur more in soft science texts to increase the grammatical intricacy of sentences. The reason for the non-sensitivity across disciplines is that evaluative adjectives tend to occur in neither soft nor hard science texts.

In tissue engineering, 3D printing is an important tool that uses biocompatible materials, cells, and supporting components to fabricate complex 3D printed constructs. This review focuses on the cytocompatibility characteristics of 3D printed constructs, made from different synthetic and natural materials. From the overview of this article, inkjet and extrusion-based 3D printing are widely used methods for fabricating 3D printed scaffolds for tissue engineering. This review highlights that scaffold prepared by both inkjet and extrusion-based 3D printing techniques showed significant impact on cell adherence, proliferation, and differentiation as evidenced by in vitro and in vivo studies. 3D printed constructs with growth factors (FGF-2, TGF-β1, or FGF-2/TGF-β1) enhance extracellular matrix (ECM), collagen I content, and high glycosaminoglycan (GAG) content for cell growth and bone formation. Similarly, the utilization of 3D printing in other tissue engineering applications cannot be belittled. In conclusion, it would be interesting to combine different 3D printing techniques to fabricate future 3D printed constructs for several tissue engineering applications.

VI paralysis is a frequent and classic pathology in the clinical consultation of ophthalmology. The main difficulty is the diagnostic process (for the etiology). In young adults, be aware of the possibility of a tumor with the correlation of rapid imaging. UCNT is frequent in Morocco, its neurological symptoms are misleading because we do not always think of examining the nasopharynx properly in the event of damage to the cranial pairs. Improving the prognosis for this cancer requires early diagnosis.

Authors: Elnour Mohammed Sally Damra , Salaheldien Rami , Ahmed Badreldeen
Published: January 2022

Congenital cervical teratomas are rare tumours of germ cells that should be diagnosed antenatally by ultrasound during anomaly scan or even earlier. The incidence of teratomas of the head and neck is 3-5%. We are presenting a case of rare cervical teratoma.1 Congenital cervical tumours are often clinically dramatic, though basically benign. Prognosis is favourable only if the airway is quickly stabilized and necessarily surgical procedure is planned and executed effectively.2 Case presentation: A 34-year-old female presented at 32 weeks of gestation, at Al Amal National Hospital where an ultrasound examination revealed a single viable cephalic fetus with a huge irregular heterogeneous anterior neck mass suspected as congenital cervical neck teratoma. The delivery was planned at 37 weeks gestation. The team was assembled for EXIT procedure which includes the obstetricians, neonatologist, anthologist, ENT surgeons. At 37 weeks of gestation, the child was maintained on maternal circulation after caesarean section until successfully intubated (Extra Uterine Intrapartum Treatment (EXIT) was performed at Al Amal National Hospital after liaison with the anesthetist, neonatologist and the pediatric surgeon. A female fetus weighing 3.8 kg was delivered and intubated immediately. Unfortunately, the newborn died at 48hours of age. Conclusion: Prenatally diagnosed head and neck teratomas can result in early neonatal death if the delivery was not planned correctly with right multidisciplinary team. In this case EXIT is the procedure of choice.

Background: Near-infrared fluorescence-based sentinel lymph node (SLN) mapping technique with indocyanine green (ICG) has been found a useful surgical modality for sentinel node detection and disease staging in endometrial cancer (EC) worldwide. Objective: We aimed to introduce the SNL mapping technology using ICG and Near Infrared (NIR) fluorescence in Argentina. We aimed to assess the overall and bilateral detection rate of ICG based SNL mapping along with verifying its feasibility and effectiveness in surgical staging. We also aimed to discover the perceptions of surgeons regarding the use of ICG as a tracer and NIR as light-medium in SNL mapping. Method: ICG SLNs identification was evaluated retrospectively. This study was performed at the Hospital Aleman de Buenos Aires in September, 2017The detection rates were calculated along with the analysis of the number of SNL observed and operative time, and time taken by overall surgery. Subsequently, the surgeons were interviewed to ascertain their opinion of using ICG SNL mapping in endometrial cancer staging. Results: Four patients with endometrial cancer were included for analysis. The overall and bilateral detection rates have been 100% and 75%, respectively. While, under white light, no SLNs were identified. The average operative time of nodes resection was estimated 2.15 minutes. The fluorescence has been used for 2.2 minutes and overall time taken by surgery was estimated 71.5 minutes. The estimated blood loss (EBL) has been lower than 50 ml. The responses of surgeons’ from the interview have been 100% positive. The cost of the procedure based on the amount of dye used was 25 dollars per patient. Conclusion: Laparoscopic ICG SLN resulted to be feasible, practical and no expensive surgical modality for uterine cancer triage.

Background: Labor is a physiological process during which the fetus, the membranes, the umbilical cord and the placenta are expelled from the uterus and water delivery has become popular, although its prevalence is unknown, it is supported by healthy women with full-term pregnancies, without complications; although there is insufficient evidence to support or discourage it. Objective: To identify obstetric and neonatal outcomes and complications in women who delivered in water and to compare them with traditional deliveries. Material and methods: It is a retrospective, observational and cross-sectional study, where 2486 women were included from a database of 4223 women assisted from 2004 to 2020 in private hospitals; Of the 2486 patients included, 1025 had a water delivery and 1461 had a conventional delivery, discarding 1737 women who underwent caesarean section from the study. The information obtained from the patients, their data obtained for this study were kept in the anonymity of the patients, where they were analyzed: non-parametric data reported in percentages using Chi square; Parametric, perinatal and neonatal data are reported as mean plus standard deviation (±SD) and analyzed using Student's T, using the SPSS version 25 statistical package. Results: A total of 2486 women were included in this study, the birth in 1025 was water delivery (24%) and 1461 was conventional delivery (35%), 1737 caesarean section (41%) were excluded from the study, no difference was observed maternal age; unlike weight, height, body mass index; they were higher in women with water birth compared to conventional. No difference was demonstrated between nulliparous (45.99%) and multiparous (53.86%) when comparing both birth in water and conventional; only increase in previous caesarean sections (9.36 vs 6.5%, p=0.008) and decrease in previous abortions (16.19 vs 20.94%, p=0.002) in water delivery with the conventional one; complications were not different: administration of oxytocin (3.2 vs 3.1) or postpartum hemorrhage (0.29 vs 0.13) in both deliveries; no differences in first degree perineal tears (21.4 vs 18.5%). Conclusion: Water birth reduces stress, pain sensation, second and third degree perineal lacerations and contributes to better newborn outcomes; the selection and inclusion of patients with low-risk pregnancies allows better perinatal results than conventional delivery; but, further studies are required to use it routinely.

Authors: Peña-Chavarria Antonio , Lizano Cecilia , Xirinachs Hilda
Published: January 2022

Los autores presentan un estudio clínico-parasitológico sobre los efectos del citrato de piperacina en 36 enfermos de fiebre tifoidea con edades variantes entre 4 y 70 años muy parasitados por Ascaris lumbricoides. Lo dosis total usada de la droga fluctuó entre 1,5 a 6 gramos y de 20 enfermos que fueron controlados coprológicamente se logró negativización com­pleta en todos ellos. Se reputa el método como de valor, principalmente por alejar el peligro de perforación intestinal por los ascárides, a que podrían estar expuestos, con mayor razón, los enfermos de fiebre tifoidea.

Anotaciones sobre una curiosa oviposición de la mosca del tórsalo en condiciones experimentales (Diptera: Cuterebridae)
Authors: Zeledón Rodrigo
Published: January 2022

A partir de 9 ejemplares de D. hominis (L. Jr.), nacidas en el labo­ratorio, se observó interesante oviposición posiblemente originada por una única hembra: tres posturas fueron hechas sobre un pedazo de vegetal seco con un total de 96 huevos; por lo menos dos posturas más en el abdomen y cabeza de una Dermatobia macho con 74 huevos en total, y 8 huevos más en el abdomen de otra Dermatobia hembra. Se hace un comentario sobre la posibilidad de transmisión del tórsalo a partir de huevos eventualmente depositados por el cuterébrido sobre objetos fijos.
Contribución al estudio de la hepatitis infecciosa y de la cirrosis hepática
Authors: Miranda Mario
Published: January 2022

Se estudian los protocolos de hospitalización de 145 casos de hepatitis y de 95 casos de cirrosis hepática ingresados al Hospital San Juan de Dios desde 1950 hasta setiembre de 1954. Se señalan las principales características clínicas y de laboratorio de am­bas afecciones, de acuerdo con el análisis del material mencionado. Los valores muy elevados de bilirrubinemia (sobre 2 mg. %) tanto en cirrosis como en hepatitis infecciosa son de muy mal pronóstico y van acompaña­dos de una elevada mortalidad. De los 145 casos de hepatitis estudiados fallecieron 7, dando una mor­talidad de 4,7%. El estudio de la procedencia de los enfermos revela una mayor incidencia de hepatitis infecciosa y cirrosis hepática, en algunos cantones de la provincia de San José. De los 95 casos de cirrosis estudiados fallecieron 37 en el hospital, dando una mortalidad de 38,9%.

Se recolectaron de distintas fuentes documentales los nombres de setenta y seis topónimos correspondientes a los principales accidentes topográficos del Parque Nacional Isla del Coco, Costa Rica. Estos se pueden agrupar en cuatro grupos principales, como son aquellos pertenecientes a las visitas de navegantes británicos, la vida republicana en Costa Rica y aquellos de la flora y fauna, tanto terrestre como marina. La metodología empleada ha permitido identificar setenta y uno de estos topónimos. Conceptualmente, el dinamismo del abordaje metodológico y la divulgación de sus resultados sugieren tener implícito un proceso de retroalimentación.
Marco geológico y tectónico de la Isla del Coco y la región marítima circunvecina, Costa Rica
Authors: Rojas Wilfredo , Alvarado Guillermo E.
Published: January 2022

La Isla del Coco es la única isla oceánica y el único afloramiento subaéreo de la Cordillera Volcánica del Coco, el rasgo geográfico y geológico más extenso en aguas territoriales costarricenses. Desde el punto de vista geológico, está conformada por rocas volcánicas, predominantemente coladas de lavas basálticas y traquíticas en menor cantidad, con rocas piroclásticas y epiclásticas subordinadas. Posee suelos, coluvios y depósitos de playas (arenas y cantos) superficiales; su topografía es muy variable pero predomina el relieve quebrado y rugoso. La Isla del Coco es la parte emergida de un volcán submarino de evolución compleja, desarrollado a partir y durante el Pleistoceno Inferior (entre 2.2 y 1.5 millones de años, Ma), producto de una anomalía térmica en el manto a través de varias fisuras, que originaron varios alineamientos de volcanes submarinos. La Isla del Coco se encuentra en un estadio de erosión activo, y sus arcos y plataformas sumergidas (90-110m y 183m) son probablemente el producto de una erosión subaérea durante las dos últimas máximas glaciaciones, combinados quizás con la subsidencia debida al enfriamiento del escudo volcánico y de la corteza oceánica. Al ser la isla geológicamente joven, posee importantes implicaciones para la comprensión de la evolución y el endemismo de su biodiversidad. Las amenazas en la geodinámica principales identificadas son los deslizamientos, los tsunamis y, en menor grado, la sismicidad, poco frecuente y con magnitudes moderadas (≤ 5.8 Mw hasta la fecha) dentro de un radio de alrededor de 300km, predominantemente asociada con fallas dextrales de rumbo N-S. Los pocos datos obtenidos hasta el momento indican que hay un cierto grado de actividad sísmica en los alrededores de la Isla del Coco, relacionados con las fallas locales. Algunos pequeños tsunamis históricos y prehistóricos han afectado a la Isla del Coco y los sismos así como la precipitación pluvial elevada han generado deslizamientos. La licuefacción está restringida a las dos playas arenosas (bahías Chatham y Wafer).
