Dear All IISEE Readers• Dear All IISEEReaders

By IISEE• Professional Lectures
on Disaster
Management Policy

The year 2023 is coming to an end. We hope that you and yourfamilies are doing well.
Although there were times that the COVID-19 pandemic forced us
to hold our training courses remotely, we were able to successfully
conduct face to face for the 2022-2023 training course.
As of today, we have accepted 13 participants from 8 countries in
the one for 2023-2024.
Also, 9 participants from 6 countries will participate in the Global
Seismological Observation Course, and we are now preparing forthe start of the program on January 9.
We have been able to continue the training course in order to
respond to the enthusiasm of the participants, thanks to thesupport and understanding of many people, which I strongly feelfrom bottom my heart. We would like to thank you once again.
To those of you who participated at IISEE course in the past, thisnewsletter aims to build a bridge between IISEE and the past
participants. We would be happy to receive your contributions
even if they are trivial, for example, about your research.
We would appreciate your continued support in the new year.
For questions and requests, please feel free to email

Note

As One-Year Training Course held at the International Institute ofSeismology and Earthquake Engineering (IISEE) is cooperatingwith the National Graduate Institute for Policy Studies (GRIPS), itis possible to obtain a master’s degree.
Training participants who are aiming to acquire a master’s degree
in disaster management policy of GRIPS attended professional
lectures on disaster management policy conducted by GRIPS fromNovember 1st to 15th.
In those lectures, GRIPS professors and visiting lecturers gave
lectures on disaster management policies related to architecture,cities, infrastructure, etc., as well as damage caused by pastdisasters and recovery and reconstruction.
In addition, they made inspection tours of Nakano and Yaesu
areas of Tokyo to observe urban redevelopment projects anddisaster preparedness efforts. They also made presentations anddiscussions about disasters in their country, disaster management
policies, and their own relationship to disaster prevention, andthose were an opportunity for participants from IISEE andICHARM to deepen their knowledge of disaster prevention in theircountries.
In Tsukuba, it is the season of cold northerly wind called"Tsukuba-Oroshi".
The cold days will continue for a while, but after the wintersolstice, the new year is just around the corner. We hope allparticipants will overcome this cold winter with a change of paceby experiencing Japanese events and culture during the year-end
and New Year holidays.

Application of Remote Sensing and Machine LearningTechnologies for Disaster Response

iiseenews@kenken.go.jp
https://iisee.kenken.go.jp/en/<Abstract>
An accurate and prompt understanding of the full extent ofdisaster aftermath is vital for effective emergency response andrelief activities. Immediately after a disaster, affected areas
become isolated and dangerous for field surveys. Thus,
effectively using remote sensing data will allow us to grasp theextent of the damage quickly. This lecture will show the basics
of applying machine learning to understand remote sensing
images in disaster response scenarios, focusing on tsunami andearthquake-induced damage.

HOKYO Project Training in El Salvador – Visit of 2
Ex-Participants to the IISEEBy IISEE
On November 15 and 16,
2023, 10 participants from El
Salvador including 2 exparticipants of the IISEE
training program, visited theBRI as part of the JICA
“Project for Capacity
Development for theBack Numbers Evaluation and Seismic
Reinforcement of Buildings in
https://iisee.kenken.go
the Metropolitan Area of San Salvador (known as the HOKYO.jp/en/newsletter/Project)”.
Researchers from the Department of Structural Engineering andInternational Institute of Seismology and Earthquake Engineering(IISEE) provided lectures, guided tours, and discussions.
Dr. Otsuka from IISEE gave a lecture on seismic retrofitting andseismic evaluation of masonry buildings based on DB.
They also toured the experimental buildings and had a discussion
about the HOKYO project at the end of the second day.
It was impressive to see Susan-san (2020-2021 Earthquake
Engineering Course) working on the HOKYO project.

Abstract
Crustal seismicity in the Central Andes is characterized by highactivity in the sub-Andean province with predominantly reverse
faulting mechanisms, and low activity in the high Andean plateau
with normal and strike-slip faults. Despite having one of thelargest orogenic plateaus, few crustal focal mechanisms wereavailable for Bolivia. We determined 13 new focal mechanisms ofshallow crustal earthquakes improving the characterization of theregional stresses. Additional recently installed stations in Bolivia,
as well as regional stations in Brazil, were used for the regional
moment tensor inversion. P-wave polarities at teleseismic stations
were also used for the largest events to better constrain the focal
mechanisms. We combine a probabilistic full waveform moment
tensor inversion with focal mechanisms derived by fitting P-wave

polarities. The cluster analysis of the whole regional data set of
focal mechanisms, including 13 new solutions plus 18 previously
published results, indicate three predominant types ofmechanisms: reverse faulting in the NW-SE trending sub-Andean
belt just north of the Orocline (north of Cochabamba) with P axes
oriented NE-SW, reverse faulting earthquakes in the N-S trending
sub-Andean belt south of the Orocline (south of Santa Cruz) with
E-W oriented P axes, and strike-slip mechanisms in the Eastern
Cordillera with NE-SW P axes. Our results map in detail the stresspattern in the Central Andes. Reverse faulting earthquakes in the
sub-Andean belt show compression perpendicular to the front of
the Andean plateau, interpreted as a combination of spreading
stresses of the plateau and plate-wide compression. Focal
mechanisms in the high plateau change to strike-slip indicating abalance between local extensional gravitational stresses in theplateau and regional compression from the Nazca plateconvergence.

2022 Meeting of International Platform forReducing Earthquake Disasters (IPRED)
By Dr. Yuri Otsuka, Research Engineer, IISEEWe held the IPRED meeting on the 26th and 29th of Sept. 2022.
IPRED is a UNESCO project implemented by IISEE and the leadingorganization of 10 countries, which keeps a firm connection withIISEE through ODA-based JICA projects and IISEE’s international
training program.
Eleven countries participated in the meeting, including Japan,Algeria, Chile, Egypt, El Salvador, Indonesia, Kazakhstan, Mexico,Peru, Romania, and Turkey, and reported on the current status ofIPRED activities. In addition to the regular annual meeting, apresentation and site visit about the 2023 Turkey earthquake
were held in light of the February 6 earthquake that struck Turkey
this year. The Japanese representative*1 reported on the statusof activities in Japan by the IPRED Action Plan. The Japanese
representative*2 reported results on the past major earthquakes
observed in Japan and these damages and on comparisons withthe seismic motions observed during the Turkey earthquake. Inaddition to these activities, we attended the presentation on theTurkey earthquake and toured. We obtained the latest knowledgeof the disaster caused by the Turkey earthquake and the seismic
standards in Turkey. Six former IISEE Training Program trainees
were among the representatives of IPRED participating countries.
