Latin American earthquake engineering course,
the first colloquium, “Inception Report
Presentation”
By Dr. Haruhiko Suwada, Senior Research Scientist, IISEEIn the 2022 Latin American course which has been conducted
remotely since May 12, the first colloquium, "Inception Report
Presentation," was held on May 25 and 26, and 10 participantsfrom four countries (Mexico, Nicaragua, Colombia, and Peru)
presented basic information on seismic codes and policies in theircountries, an overview of their organizations and duties, issues
they face in their work, and their expectations for this training
course.
The common problems that were pointed out in many countries
included the fact that although seismic codes themselves exist,
they are not always observed due to a lack of engineers,
inadequate management systems, etc., and that technologies forseismic evaluation and seismic retrofit of existing buildings that do
not comply with the standards have not yet been established.
This training course is designed not only to improve theknowledge of the participants themselves, but also to provide
them with advice throughout the entire process on how toformulate their own action plans for improvement based on theirunderstanding of these realities in their respective countries.

Congratulation for the 70th anniversary of theDOST-PHIVOLCS
By Dr. Tatsuhiko Hara, Chief Research Scientist, IISEEThe 70th anniversary symposium of the Department of Scienceand Technology - Philippine Institute of Volcanology andEarthquakes
Seismology (DOST-PHIVOLCS), “Advances in SEVENTY (ScienceThe 2011 off the Pacific and Technology in Years) and DRRM” was held on June 21, 2022
at the PHIVOLCS Auditorium, Diliman, Quezon City. The IISEE
coast of Tohoku
Earthquake
seismology and tsunami staff sent a congratulatory message forthe 70th anniversary, which was introduced during the symposium
Reports of Recent
Earthquakes
with many messages from researchers and officials of national andforeign organizations. Some of the IISEE staff attended theUtsu Catalog
symposium online. We were much impressed by the advances
Earthquake Catalog
which were presented that were achieved by the DOST-PHIVOLCS
in various fields including multi-hazards in its history.

Research paper co-authored by Dr. Hayashida andDr. Yokoi was published online in Journal ofSeismology
By Dr. Takumi Hayashida, Senior Research Scientist, IISEEThe seismic velocity structure of the shallow ground largely
influences the ground shaking behavior during earthquakes.
Microtremor surveys are widely used as a method to estimate
surface S-wave velocities. A research paper co-authored by Dr.
Hayashida and Dr. Yokoi (Visiting Research Fellow of IISEE) wasavailable online in Journal of Seismology on April 23 (Asten et al.,2022; published on January 1). Dr. Michael Asten (ResearchDirector of Earth Insight: former professor at Monash University,Australia) is the first author. In the paper, experts worldwide
analyzed the same microtremor records and discussed how muchthe results vary depending on the analyst, the methods used, thedecisions made, the amount of information given in advance, andthe software used. IISEE team used the tool available on ourwebsite (https://iisee.kenken.go.jp/net/?mod=spac) to estimate
the velocity structure models and confirmed that the results werecomparable to those of other participants.
The paper can be accessed free of charge at the link below. Please
read it if you are interested.
