Hope you, your family and your colleagues a happy andprosperous new year.

At the beginning of the newyear, 1,815 ex-participants from 100
countries were counted, and in the
Global Seismological Observation
Course started from January 17 moreparticipants are present including one
from the 101th country Timor Leste.
In 2017, damaging
Dr. Yokoi
earthquakes took place in China, two
in Mexico, one in Oaxaca another in Puebla, and in Iran-Iraq borderregion. We’d like to express our deep sympathy with those who in theaffected area. These catastrophes made us reconfirm the necessity tokeep IISEE’s high mission through our training courses for mitigating
earthquake disasters and for making people living in the earthquakeprone countries more safely and peacefully.
Humanity of this century seems to have technologies and wisdom
for coexisting with the harsh natural phenomena earthquake disasters.
Unfortunately, we have to say that these have not yet been spread wellto all over the world.

Dissemination of Earthquake Engineering and Earthquake Science
as well as IISEE’s international training courses is now required, to keep
The 2011 off the Pacific and improve them as the properties common to all human beings
through dozens generations in a sustainable way until the next
coast of Tohoku
millennium.

The 2017 Global Seismological Observation
Training Course has started

By Mr. Yoshihiro Iitake, Head of Administration Division, IISEEThe Global Seismological Observation Training Course has stared
on January 16th, 2018. There are 17 participants from 17 countries(Algeria, Bangladesh, Bhutan, Cuba,Egypt, Fiji, India, Iran, Myanmar,Namibia, Nepal, Pakistan, Samoa,
Solomon Islands, Thailand, TimorLeste, and Zimbabwe) joining thistraining course.
The Training Course has thespecial aim to develop humanresources having acquired the skills
necessary for detecting nuclear
tests applying seismologicalknowledge. Since 1995 until now,
226 participants from 71countries
has completed.

MOFA Mr. Taguchi

Training participants of thisyear is working actively to learn theknowledge about the international
seismic observation and acquire
advanced earthquake analysis
technique.
I hope that they could enjoy
staying Japan in addition to thetraining then go back to theircountries with good memory.

BRI

Dr. Midorikawa*The Global SeismologicalObservation Training Course iscarried out by the support andcooperation of CTBTO, MOFA, JICA,
JMA and other organizations.

Enjoy, Now

Field Survey for Building Damages due to the2017 Central Mexico Earthquake

By Dr. Tatsuya Azuhata, Chief Research Engineer of IISEEOn 28th Nov. -5th Dec.,
the BRI dispatched tworesearchers, Dr. Tatsuya Azuhata(IISEE) and Dr. Akihiro
Nakamura (Dept. of StructuralEngineering) to conduct a fieldsurvey for the building damage
caused by the 2017 CentralMexico earthquake which
occurred on 19th Sept.
First, they visited thePhoto.1 Example of collapsed building
National Center for Disaster
Prevention of Mexico (CENAPRED), heard the damage survey results by
the CENAPRED and discussed them. From the second day, theyobserved the damaged area in Mexico-city under the support of researchstaffs of the CENAPRED and visited the National Autonomous Universityof Mexico to acquire information relating to the building damages.
About 40 buildings collapsed due to this earthquake. Most of themwere designed following the previous building design codes issued
before 1985, and their number of stories approximately ranged fromfive to seven. Long-period earthquake ground motions did not occur.
Thus, high-rise buildings were hardly damaged.

In Mexico-city, building
damages were limited. This
result suggests the effectivenessof the seismic building codes
revised after 1985. Dr. Azuhata
and Dr. Nakamura now continue
to investigate the relation
between the seismic designcode and building damage, etc.
in more detail and will publish
their research results soon.
