One person in Hiroshima and one person in Ehime were reported dead. About 3,700 buildings were damaged in the Hiroshima area.[1] Liquefaction was observed in Hiroshima[2] and Ehime.[3] Power outage occurred in the prefectures of Hiroshima, Ehime, Okayama, Yamaguchi, and Kōchi. The maximal intensity was shindo lower 6 in Hiroshima.[4] This earthquake could be felt along the eastern and southern coasts of South Korea.[5] The released seismic moment of the earthquake was 1.3×1019 Nm. This earthquake is a normal faulting in-slab event within the subducting Philippine Sea Plate.[6] The slip of the earthquake was estimated to be about {{convert|1.5|-|2.4|m|sp=us}}. The locations of aftershocks were distributed roughly in N-S direction.[7] It has been suggested that this earthquake was related to the dehydration of the Philippine Sea Plate slab.[8] In this region, a strong earthquake occurred in 1905, which was also an in-slab event within the subducting plate.[9] See also
