*On March 26th at 5:41 a.m., there was an M5.2 earthquake at a depth of 50 km (data for both magnitude and depth are currently tentative), which registered a maximum seismic intensity of 5 upper in part of southern Hiroshima Prefecture. This event was an aftershock to the M6.4 (tentative) earthquake at a depth of 50 km that occurred on March 24th in Aki Nada, and occurred within the area of occurrence of other aftershocks to the event thus far.
