We applied synthetic aperture radar interferometry using Phased Array type L‐band Synthetic Aperture Radar on the ALOS satellite to investigate local deformation around volcanoes associated with the earthquake. We estimated the fault‐slip distribution along the trough based on obtained interferograms and crustal deformation from GEONET, and the estimated fault model explained the observed coseismic deformations well. The residual suggested local deformation around the Akita‐Komagatake, Kurikoma, Zao, Azuma, and Nasu volcanoes. Their deformations were obtained from independent synthetic aperture radar pairs. Additionally, deformations in the Kurikoma, Zao, and Azuma volcanoes were confirmed by GEONET data (no GEONET stations are located in the deformation areas of other volcanoes). These facts indicate that the obtained local deformations must be actual deformations, rather than noise. Our hypothesis is that coseismic extensional deformation concentrates in the soft medium under a volcano (e.g., magma and its surrounding rock) and that this deformation has caused local deformation with subsidence. To validate this hypothesis, we carried out numerical experiments using the finite element method for a soft medium under a volcano. Distributions of observed local deformations stretch in the direction of the minor principal axis of strain, and such distributions were obtained in this experiment, indicating that the hypothesis is plausible. Conceivably, such a concentration of coseismic deformation in a magma chamber may induce a volcanic eruption.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004230362740999","@type":"Researcher","foaf:name":[{"@value":"T.
