The 2011 off the Pacific coast of Tohoku Earthquake occurred on March 11, 2011 and shook Miyagi Prefecture with a strong earthquake of magnitude 7 (Japanese scale) . A vast range over an east part of Japan suffered damage by a strong ground motion, moreover wide range of the pacific coast of Tohoku area suffered damage by Tsunami. The earthquake caused damage to hazardous material facilities in petrochemical industrial complex. For example, some of them caught fire after the earthquake and large amount of oil leaked from oil storage tanks. National Research Institute of Fire and Disaster have investigated damage including the fires and failures of the hazmat facilities. <br>In this paper, the author reports the outline of the result of the investigation. The damage of the hazmat facilities has a different aspect by area. The oil storage tanks and other hazmat facilities damaged mainly by the Tsunami on the pacific coast and the strong ground motion caused the liquefaction of the foundation ground. On the coast of the Sea of Japan, the earthquake generated sloshing of liquid in large oil storage tanks and caused oil spill on the floating roofs and caused damage to the pontoon of the floating roofs. Moreover, on the shore of the Bay of Tokyo, one of the floating roofs sank after the earthquake because the deck of the floating roof cracked during the earthquake and lost buoyancy.
