The earthquake Catastrophe moved Motion Honshu ( the main island of Japan ) east , shifted Motion the Earth on its axis by estimates Scrutiny of between and , increased Cause_change_of_position_on_a_scale earth 's rotational speed by 1.8 µs per day , and generated Creating infrasound waves detected Know in perturbations of the low-orbiting GOCE satellite .

The bulk of the object 's energy was absorbed by the atmosphere , with a total kinetic energy before atmospheric impact Influence estimated from infrasound and seismic measurements to be equivalent to the blast yield of 400–500 kilotons of TNT ( about 1.4–1.8 PJ ) range – 26 to 33 times as much energy as that released Causation from the atomic bomb detonated Attack at Hiroshima .
