The Kumamoto Earthquake has caused extensive damage to a variety of facilities along ground ruptures that appeared along both the known and hidden fault zones. Moreover close to 500 millimeters of rain fell in the quake-hit areas on June 20 and 21, causing further extensive damage, highlighting the difficulty to cope with earthquake-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.
