GROUND DEFORMATION BUILT UP ALONG SEISMIC FAULT ACTIVATED IN THE 2016 KUMAMOTO EARTHQUAKE

摘要

The Kumamoto Earthquake has caused extensive damage to a variety of fascilities alog ground ruptures that appeared along the known trace of Futagawa fault. Moreover close to 500 millimeters of rain fell on some parts along the quake-hit areas on June 20 and 21, causing further extensive damage, highlighting the difficulty to cope with earth-quake-flood multi hazards. This paper describes some unique features of ground deformations that appeared along the fault, and the effect of the heavy rain on some of these deformed grounds.
