Interim Presentation held on July 9
By Dr. Tatsuya Azuhata, Director of IISEEOn July 9, we held an interim presentation as a part of individual
training. In this session, all participants presented the interim results of
their study. We value these opportunities, which allow them to practiceand brush up on their presentation skills.
S and T courses had a joint session, and E-course had their session
separately. To prevent CIVID-19 infection, we continued to take thecountermeasures from the last year, including using larger rooms for thevenues.
We expect all participants to continue their research vigorously and dotheir best to maintain their health. A healthy body is essential inachieving goals, and we don't want their efforts to result in vain.

The International Institute for Seismology andEarthquake Engineering (IISEE) – Building
Research Institute (BRI) conducted a two-day
study trip in Nigata prefecture. Students oftwo different courses, namely Seismology andEarthquake Engineering, participated in thisevent. The tour was composed of visits toseveral historical places related toearthquakes and other induced disasters, e.g.,
Nagaoka Earthquake Disaster Archive Center(Kioku Miral), Kogomo Memorial Park,
Yamakoshi Restoration Exchange Centre(Orataru), and City Hall Plaza (Aore Nagaoka).
Through an aerial photomap of Nagaoka we observed the state of theaffected area from the Chu-Etsu earthquake. We saw 3D documentaries
that enlighten us on the restoration process conducted in the submergedarea caused by dammed river from the earthquake-induced landslide.
We visited one of the well-preserved submerged houses, the City hallwith an aesthetic façade and roofed open plaza (Nakadoma), a uniquearchitectural and structural creation, and many exciting places like
Alpaca Farm.
Participating in this study trip, I felt that Japanese peoples never lose
their hope for survival. I realized the hard effort and unity among them
maintained during the restoration process from different recurring fatal
natural disasters which causes the death of countless valuable life anddamage to infrastructures. I learned that these natural disasters werecausing not only damage to people and property; they also taught thevillagers costly lessons to improve and upgrade their technologies
regarding housing, land usage, etc.
This visit was very fruitful for me. I am delighted to participate in thisstudy trip and grateful to the organizer for arranging such a successful
event despite the global pandemic situation caused by Covid-19. I hopefor the continuation of these study trips for the succeeding participants
as well.

Your original papers will
be reviewed by theeditorial members andsome experts.
NO submission fee isneeded.

The two days’ study trip to Nagaoka city wasvery informative and enjoyable. The trip
mainly focused on observing the Chuetsu
earthquake of 2004 that caused tremendous
damage to the Yamakoshi village of Nagaoka
city. The study tour began at Nagaoka
Earthquake Archive Center - Kioku Mirai.
The museum holds documentaries andnumerous picture archives showing thedamages caused by the earthquake inYamakoshi district and the rescue missions
carried out after that. The museum also
included simple evacuation structure models made of cardboard,
designed post-earthquake in recognition of the lack thereof. A mostrecent evacuation structure model designed under the guidelines of
COVID-19 is also available, which is a timely and commendable
undertaking of the museum.
On the second day of the trip, we visited Orataru (Yamakoshi
Revitalisation Center) and Kogomo Memorial Park in the Yamkoshi
district. The area is mountainous terrain and was the site of numerous
landslides triggered during the earthquake, almost completely isolated
the village. The revitalization center also holds numerous photo archivesof the disaster. The archives at the center also captures themanagement and the means of the relief and rescue missions carriedout. Coming from a mountainous country that is vulnerable to both
earthquakes and landslides, the visit to the museum held a lot ofsentimental values for me. After an educative session, we made a final
stop at the Yubu Alpaca farm, which was a refreshing end to trip.

Report on the 30th International Tsunami
Symposium (July 1-3)
By Mr. Geronimo Pulido I. (Chili, T-Course)The 30th International Tsunami
symposium was in Sendai, the capital cityof Miyagi Prefecture, the largest city in theTōhoku region.
The overall reason to attend thissymposium was to see from first hand thecurrent research and development in thefield of tsunami forecasting, early warning,instrumentation, interaction withstructures, experimental methods, fieldsurveys, education, and more. The primaryobjective of the symposium was to"establish and maintain high standards of professional conduct formembers related to the field of various energetic topics." Also, thetheme of this year's symposium was the 10-year commemoration of the2011 Tohoku earthquake and tsunami and how the lessons andexperience obtained from this event will be passed to future
generations. This was the opening topic of the first day of theContact Us

12 participants visited National Research Institute for Earth Science andDisaster Resilience (NIED) on July 14th morning. 3 participants
participated in the online lectures from their respective countries. First,
they watched an introductory video of the institute, then observed theLarge-scale Earthquake Simulator. In the online lecture, the lecturer
introduced the Network Center for Earthquake, Tsunami and Volcanoand Monitoring of Waves on Land and Seafloor called MOWLAS which isa high-density seismic network. Another lecturer from the Earthquake
Disaster Mitigation Research Division gave the research progress related
to a performance of structures subjected to earthquake impacts atThree-Dimensional Full-Scale Earthquake Testing Facility (E-Defense) inMiki, Hyogo. The participants’ high interests made active discussions.
