Popis: On April 13, 2013, a MJMA6.3 earthquake occurred in the Awaji Island. Epicenter located southwest of the active fault system ruptured by the 1995 Hyogo-ken Nanbu Earthquake. We installed the temporal seismic stations around the epicenter immediately after the mainshock. Using data of these temporal stations, we determined the focal mechanisms of aftershocks precisely. Although, we could find various types of mechanisms in the aftershock sequence, most of them occurred under the E-W compression stress field as like with other earthquakes in the Kinki Area. However, aftershocks in the area of southeast of the mainshock have the P axes of NE-SW direction.
