The 2012 Kamaishi earthquake occurred near the city of Kamaishi, Japan, on December 7.[10] The magnitude 7.3 shock generated a small tsunami, with waves up to 1 m high, that hit Ishinomaki in Miyagi Prefecture.[11] It occurred at a depth of 36 km within the Pacific Plate and was the result of reverse faulting, about 20 kilometres (12 mi) east of the Japan Trench.[1]



The 1 metre (3.3 ft) tsunami caused a mountain of sandbags to collapse in Ishinomaki.[8] An old man went missing and was found dead on December 14 after he sailed out to sea to try to evacuate from the tsunami in Kuji.[7][8]


Some pipeworks were damaged in an old people's facility in Saitama.[2] Some boards in a roof of an elementary school in Ichikai shifted.[12] An old lady died of shock at her home in Marumori, and a man died of shock after trying to evacuate from where he was working in Iitate, causing a total of 3 deaths.[7] This earthquake also caused 14 injuries.[8]
