DamageTsunamiThe {{convert|1|m|ft}} tsunami caused a mountain of sandbags to collapse in Ishinomaki.[7] 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.[6][7] ShakingSome pipeworks were damaged in an old people's facility in Saitama.[1] Some boards in a roof of an elementary school in Ichikai shifted.[11] An elderly 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.[6] This earthquake also caused 14 injuries.[7] Previous earthquakes in KamaishiIn 2001 and 2008, there were a series of micro earthquakes that could have started the tectonic plate movement that spawned the 2012 Kamaishi earthquake. These small series of earthquakes were a magnitude of about 3–4.9. It is studied that the shocks moved from the outer and deeper limits into the mainshock epicenter. These small earthquakes were a precursor that began the tectonic movement for the 2012 earthquake.[12] See also
