Context in the mentioned source: "As illustrated in map 25.2, the March 11 earthquake had a very large epicentral and tsunami source area, larger than any earthquake recorded in Japan’s history. Furthermore, its magnitude of Mw (moment magnitude) 9.0 exceeded the hazard level of any earthquake in the country ever considered for purposes of disaster management. Thus, the extent of the high seismic intensity area of the actual earthquake was much larger than expected, and the area that experienced Japanese seismic intensity of 5+ or larger was about 10 times the estimate (map 25.4). Furthermore, the actual tsunami height was twice the height used in the predisaster tsunami hazard predictions (map 25.5).
