Professor Kishiki and his research team participated in the field investigation of earthquake-damaged buildings following the 2026 Kumamoto Earthquake

Professor Shoichi Kishiki, Professor Tadashi Ishihara and Associate Professor Takaharu Nakano of the Multidisciplinary Resilience Research Center, Institute of Integrated Research, Institute of Science Tokyo, participated in a field investigation of earthquake-damaged buildings following the 2026 Kumamoto Earthquake (which occurred on July 28, 2026).

Professor Kishiki and a team of structural engineering experts entered the affected area and commenced inspections on July 31, three days after the earthquake. The team has continued its investigations through multiple site visits during August.

The survey team is conducting detailed assessments of damage to affected buildings and analyzing the relationship between seismic ground motion and structural damage. In addition, the team has directly inspected seismic isolation layers in critical facilities such as city halls and hospitals to examine the operational condition and performance of seismic isolation systems.

Based on the specialized knowledge gained through these field investigations, Professor Shoichi Kishiki provided commentary through various media outlets, including television, online videos, and news websites, on the seismic isolation system of Yatsushiro City Hall and the building damage caused by the 2026 Kumamoto Earthquake.

These field survey activities play an indispensable role in determining whether damaged buildings can continue to be used safely and in supporting decisions regarding their prompt recovery and restoration.

The findings from these investigations have also been incorporated into the Disaster Response Headquarters Meeting Materials published on the official website of Yatsushiro City. The survey results serve as one of the important factors in considering the city's future recovery policies and making decisions.
