What time did the tsunami in japan happen their time?

Answer 1

The earthquake giving rise to the tsunami occurred at 6,000 feet below sea level 80 miles from northern Japan and 240 miles from Tokyo. Seismic waves (sound traveling through the solid crust of the earth below the ocean floor) move at around 14,000 KM/hr or about 8,300 miles/hr. This means that the shock wave hit northern Japan (80 miles away) about 36 seconds after the quake. Japan knew, at least at this point, that a tsunami and probably a tidal wave were on their way and would hit the island nation within minutes. With the modern warning systems that are in place using both radio and sound equipment, Japan knew the moment the quake occurred that a tsunami was on its way.

A tsunami travels at about 600 mph which means that it would have reached northern Japan (80 miles away) about 8 minutes after the quake and Tokyo (240 miles away) in about 24 minutes. The actual time was probably slightly greater because a tsunami slows as it gets into shallow water so it was probably attenuated considerably from its spot of origin to the various points of contact with land thus increasing the time of travel somewhat.

Answer 2

The major 9.0 magnitude earthquake occurred off the coast of Japan at 2:46:23 PM (local time) on March 11, 2011, or 05:46:23 UTC followed a few minutes later by a large tsunami. At 3:27pm, the first tsunami strikes the Fukushima nuclear plant.

Answer 3

The large tsunami that occured in Japan hit on March 11th, 2011.

Answer 4

The earthquake occurred at 14:46 local time (05:46 UTC) on Friday 11 March 2011.

Answer 5

Just a few miles off the north-east coast, the earthquake shifted part of the sea bed upwards, dissplacing the ocean water above it and sending a tsunami towards Japan.

Answer 6

The major 9.0 magnitude earthquake occurred off the coast of Japan at 2:46:23 PM (local time) on March 11, 2011, or 05:46:23 UTC followed a few minutes later by a large tsunami.

Answer 7

2:46pm local time

Answer 8

The Tohoku Tsunami in Japan was in 2011

Answer 9
