WORLD'S LARGEST EARTHQUAKES IN 2012
Abstract
There were 62 earthquakes in the world in 2012 that either reached or exceeded a moment magnitude (MW) of 6.5, causing major damage to buildings and other structures, or claiming human lives. Two earthquakes had moment magnitude greater than 8.0 and 13 between 7.0 and 7.9. There were 17 earthquakes that claimed human lives; in total there were at least 768 victims. The most devastating earthquake in 2012 happened on 11 August in northwestern Iran which claimed 306 casualties. The 11 April earthquake offshore the west coast of Northern Sumatra ranked first in terms of released energy, with a moment magnitude of 8.6. The deepest earthquake happened on 14 August in the Sea of Okhotsk with a hypocentre 626 km below the surface and the moment magnitude of 7.7. The strongest earthquake in Europe with the moment magnitude 6.0 happened on 20 May in northern Italy in the Emilia-Romagna province. Nine days later, on 29 May, another strong earthquake hit the same epicentral area (MW = 5.8). The two earthquakes claimed 24 casualties and were felt also in Slovenia.
