Damage Situation Around the Strong Motion Stations in the 2022 off Fukushima Prefecture Earthquake and Correspondence of Damage to Buildings with Strong Ground Motions

Abstract

We carried out damage investigation around the strong motion stations where high JMA seismic intensity scales were recorded in the 2022 off Fukushima Prefecture earthquake. We found some minor damage such as damage to the outer wall, but heavily damaged buildings were not found around all the strong motion stations. We investigated the correspondence of strong ground motions with damage to buildings. Short period below 1 sec were dominated and the 1–1.5 s response which correlates with heavy damage to buildings was small in most of the ground motions.
