seismic data
And a Clock :-)
It occurred on the 11th of March (2:46) PM Local Time.
The Haiti earthquake occurred on January 12, 2010 at approximately 4:53 PM local time.
The Big One struck at 2.46 pm local time (5.46 am UCT) on March 11 2011.
Quantitive evidence is evidence that has to do with numbers. For example. the magnitude of an earthquake the time the earthquake occurred and the length of the earthquake are all types of quantitive evidence
The magnitude 9.0 earthquake off the coast of Japan occurred on March 11, 2011 at 05:46:23 (UTC) or 2:46:23 PM (local time) at the epicenter. The tsunami occurred shortly after that.
The Alaskan earthquake occurred on Good Friday, March 27, 1964, at 5:36 PM local time.
A Tsunami can travel as fast a jetliner in flight which is anywhere from 500-600 mph. The earthquake occurred about 80 miles of the coast, although a Tsunami will slow as it hits the coast line, you can figure residents had anywhere from 8 - 15 minutes to get to higher ground. Not much time!
The Christchurch earthquake in New Zealand occurred on September 4, 2010, at 4:35 am local time.
The recent (2010) earthquake in Haiti occurred on Tuesday, January the 12th, 2010 at 21:53 UTC / GMT (or 16:53 Haitian time). For further information, please see the related questions.
The 2011 Tohoku earthquake occurred at 2:46 JST ( Japanese Standard Time ). The epicenter of the earthquake was around 45 miles east of the Oshika Peninsula of Tohoku.
To time a 5.7 (typically referring to a 5.7 earthquake), you need to use a seismometer to record the seismic waves generated by the earthquake. The time of the earthquake can be determined by analyzing the arrival times of the P-waves (primary waves) and S-waves (secondary waves) on the seismogram. The difference in arrival times helps seismologists calculate the distance to the epicenter, while the time of the first P-wave arrival indicates the exact moment the earthquake occurred.
The magnitude 9.5 earthquake in Chile occurred at 19:11 GMT (14:11 local time) on the 22 May, 1960.
