The U.S. Geological Survey (USGS) said the March 11, 2011 magnitude 9.0 Japan earthquake (originally reported as 8.9) was the "biggest quake to hit Japan since record-keeping began in the late 1800s and one of the biggest ever recorded in the world".
U.S. government scientists at USGS originally put the Japan quake at 8.9. The change to 9.0 means that the quake was about 1.5 times stronger than initially thought.
UPDATE: Official magnitude was updated to 9.1 on Nov 7, 2016.
The earthquake that hit Japan in 2011 is commonly known as the Great East Japan Earthquake, or the Tohoku earthquake and tsunami. It occurred on March 11, 2011, and had a magnitude of 9.0, triggering a devastating tsunami.
The magnitude of the 2011 earthquake in Christchurch, New Zealand, was 6.3 on the Richter scale.
The magnitude of an earthquake is a number used to quantify how much energy was released during the earthquake. The earthquake in Japan that occurred on Friday, March 10, 2011, had a moment magnitude of 8.9.
The most recent large earthquake of magnitude 9.0 or larger was a 9.0 magnitude earthquake in Japan in 2011 (as of March 2011), and it was the largest earthquake since records began. No, it wasn't. The largest earthquake ever recorded was the Chilean earthquake on May 20th, 1960. It measured 9.5 magnitude on the Richter's scale.
The Christchurch in New Zealand, had an earthquake of a 4.8 magnitude which happened on March 6, 2011 3:43am. This was an aftershock of the last months earthquake, February 22, 2011 which was 6.3.
The Tsunami in Japan in 2011 was caused by an earthquake gesitering a magnitude 9.0.
The largest earthquake that occurred off the coast of Japan on March 11, 2011 was originally calculated as magnitude 8.9, but later changed to 9.0 independently by both USGS and Japanese seismologists.The change to 9.0 means that the earthquake was about 1.5 times stronger than initially thought.UPDATE: Official magnitude was updated to 9.1 on Nov 7, 2016.
The 2011 Japanese tsunami was caused by a magnitude 9.0 earthquake off the coast of Japan. The earthquake generated a series of powerful tsunami waves that devastated coastal areas and caused widespread destruction.
The initial estimate of the magnitude of the Japanese earthquake that occurred on Friday, March 11, 2011 was 8.9 but this has since been increased to 9.0 as more data has been analysed.
