PEER Response to M7 Kumamoto Earthquake

The M7 earthquake on the southwest island of Kyushu, Japan, on April 15 has caused severe damage and collapse of many buildings resulting in a significant number of casualties. This event occurred one day after a series of foreshocks in the same region, which included M 6.2 and M 6.0 earthquakes. The April 14 events resulted in at least 9 fatalities and over 800 injuries. Refer to the USGS summary for more information.

Since the initial earthquake, PEER has reached out to PEER core institutions, industry partners, and colleague organizations, some who are in the effected area. On April 20, PEER hosted an “information hub” conference call where colleagues shared information about field conditions and reconnaissance plans. Preliminary reports state that rescue efforts are hindered by heavy rain and significant ground failures. Roads have been adversely impacted. The situation is in flux, and there will be things that can be learned about site effects, structures, infrastructure performance, performance of building contents, impact to businesses, and the local and global economy.

Refer to the Earthquake Briefings page for more information and resources.

PEER will continue to monitor the situation and determine appropriate actions. For inquiries please contact Grace Kang, Director of Communications, at
