抄録（英）：
In order to investigate the behavior of a rock cavern during earthquakes, earthquake observations have been carried out in the Shin Usami Tunnel along the JR's Ito Line. In July 1989, the earthquake swarm occurred off the east coast of the lzu Peninsula. The epicentral region was very near to the observation site, so many records were obtained. On the other hand, the simplified method for estimating the strain of a cavern during earthquakes had been formerly proposed by us. From the comparison between the observed strain and the strain estimated by the proposed method, the adequacy of the method for near-field earthquakes was suggested.
