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