REPORTING · 11th March 2011
Merv Ritchie
In the first sixteen hours after the 8.9 magnitude quake struck, 108 more tremors were recorded measuring greater than 5.0, twenty of which were greater than 6.0 (That's better than one every ten minutes)

The main media generally only report the significant large quakes. Every once in a while another media will report an aftershock. It might then become general perception that there are only a few. The truth is for days prior to the devastating 8.9 magnitude quake the tiny island of Japan has been steadily shaking. It must be terrible to live today in the region where every few minutes the ground rumbles. Today the shaking barely stops.

These lists of quakes are only ones that register above 5.0. There are thousands of smaller ones.

To read the numbers below, the first is the Richter scale measurement. The 2nd set of numbers is the date and time (UTC) the next two numbers are the exact location, longitude and latitude, and the last number is the estimated depth of the tremor (km).

This list was recovered at 2 pm Friday, March 11.
