Mapping, monitoring, and assessing technologies and related studies and applications play a significant role in disaster management and disaster risk mitigation. In recent years, synergies of modern and innovative methodologies have augmented the efficiency of disaster mapping shortly after their advent and made it possible for involved scientists and researchers to acquire and analyze related data and to disseminate critical information to first responders during emergencies, authorities involved in disaster management and recovery processes, the affected population, and the general public. This present Special Issue comprises 10 research papers addressing various issues of mapping and monitoring disasters and assessing their impact. They highlight recent advances in the field and are valuable for understanding the complexity of the generated phenomena. The phenomena and their effects included in this Special Issue can be divided into: (i) earthquakes and related ground deformation [1, 2, 3], (ii) earthquake-triggered landslides (ETL) [4, 5, 6], (iii) landslides triggered by hydrometeorological hazards comprising medicines [6, 7], (iv) tsunamis [8], and (v) wildfires [9, 10]. [PERSON] et al. [1] present the results of monitoring seismicity and ground deformation in the Ionian Islands (western Greece) during a period of intense seismic activity (2014-2018) with destructive earthquakes. Joint pre-, co-, and post-seismic ground deformation and seismological analysis is performed based on geodetic data from the commercial and institutional continuous Global Navigation Satellite System (GNSS) networks in the area, as well as seismological data from the Hellenic Unified Seismic Network (HUSN), respectively. [PERSON] et al. [2] monitored the 2020 to 2021 Thiva (Central Greece) earthquake sequence. They utilized double-difference relocation to assemble a high-resolution earthquake catalogue and examine, in detail, the distribution of hypocenters and the spatiotemporal evolution of the sequence. By applying instrumental and imaging geodesy, they delineated the local deformation and identified long-term trends that could have contributed to stress loading. [PERSON] et al. [3] monitored the 27 September 2021, Mw = 6.0 Arkalochori (Crete, southern Greece) earthquake. They conducted interdisciplinary research comprising geological mapping, tectonic analysis, fault photorealistic model creation by unmanned aerial system (UAS) data processing, as well as post-seismic surface deformation analysis by differential interferometry synthetic aperture radar (DInSAR) image interpretation coupled with accurately relocated epicenters recorded by locally established seismographs. [PERSON] et al. [4] applied UAS-aided photogrammetry and terrestrial laser scanning (TLS) to high-visit coastal areas in the western part of Lefkada Island (western Greece), often affected by ETL. This application aims to explore how the capabilities of these cutting-edge methodologies contribute to the improvement of our understanding on and monitoring of the structural integrity of slopes. This approach allows the initial identification of high-risk zones and the subsequent prioritization of measures and strategies for risk-mitigation-driven development. [PERSON] et al. [5] studied ETL from historical times to present in Cephalonia Island (western Greece). Based on scientific publications and numerous contemporary sources,they compiled an inventory of sites affected by ETL, several of which caused human losses and injuries.
