The 2011 Sendai, Japan earthquake was an 8.9 magnitude earthquake. It was located off the east coast of Tohoku, Japan on Friday, March 11, 2011 at 05:46:23 UTC at a depth of 24.4 km (15.2 miles). Originally a 7.9, it was upgraded to an 8.8, then again to an 8.9 by the United States Geological Survey.
The earthquake occurred on 130 km (80 miles) east of Sendai, Honshu, Japan. It presented a possibility of triggering tsunami in the area as well as in Yoshi, Japan. The quake rattled buildings and toppled cars off bridges and into waters underneath. In Tokyo, crowds huddled together and tried to reach relatives via cell phone. Its epicenter was 373 kilometers (231 miles) from Tokyo, the United States Geological Survey said. A 7.7 aftershock was reported 30 minutes following the initial quake. As a result of the quake, smoke could be seen rising from a building in Tokyo port while Shinkansen bullet trains stopped and Haneda Airport suspended operation after the quake struck.
More than 4 million buildings lost power, and many buildings caught fire.
The earthquake triggered a tsunami warning for Japan's pacific coast and various other countries, including Russia, Guam, Philippines, Indonesia, Papua Guinea, Nauru, Hawaii, northern Marinas and Taiwan. The tsunami warning issued by Japan was the most serious on its warning scale, implying that the wave was expected to be 10 meters high. A 0.5 meter high wave hit Japan's northern coast.
