USGS Dr. Dave Applegate says the Japan earthquake ruptured a 180 mile long by 50 mile wide section of the Earth's crust.
Scientists from the United States Geological Service answered questions from the public this afternoon, with some startling revelations made.
* The first tsunami wave in Samoa was reportedly one foot tall, but the seventh wave was much larger, indicating coastal areas shoudl remain on tsunami advisory well after the first wave hits, even if that wave appears small.
* 100+ aftershocks have rated 5.0 magnitude or more in Japan since the initial shake.
* Earth's axis has reportedly shifted ten inches as a result of the quake, and Japan's coast is said to have permanently shifted 2.4 metres.
* The quake was 900 times stronger than the quake that hammered San Francisco in 1989.
* Aftershocks from the Peru earthquake of almost a year ago are still felt to this day.
* Honshu earthquake occurred on ocean floor of the Pacific plate, bumping 250 miles of coastline.
* Shaking was felt as far away as China.
* The Honshu quake was not as large as the 1964 Alaska earthquake, but was comparable to the recent Chile earthquake.
* Tsunami waves that hit California earlier today washed three onlookers out to sea. Two have been recovered.
* St Louis, Missouri media outlets report that city has moved an inch as a result of the quake.
* Waves from the ensuing tsunami reached 32 feet high.
