What was the energy of the Japan earthquake?
This earthquake released a surface energy (Me) of 1.9±0.5×1017 joules, dissipated as shaking and tsunamic energy, which is nearly double that of the 9.1-magnitude 2004 Sumatran earthquake that killed 230,000 people, and flung the 2,600 ton Apung 1 ship 2 to 3 km (1.2 to 1.9 mi) inland. To give that some perspective, if we could harness the surface energy from this earthquake, it would power a city the size of Los Angeles for an entire year. The total energy released (Mw) was more than 200,000 times the surface energy and was calculated by the USGS WPhase Moment Solution at 3.9×1022 joules, slightly less than the 2004 Sumatra quake. This is equivalent to 9.32 teratons of TNT(approximately 600 million times that of the Hiroshima bomb, or 186,400 times as powerful as humanity's largest-ever explosive device, the Tsar Bomba).
