Map 7, 2014 – Global Earthquakes, Quantity Per Day: Of the 5,464 earthquakes, greater than or equal to 6.0 magnitude from January 1, 1973 to February 9, 2013; some days saw multiple quakes per day. This is summarized in the chart above.
For example, the first column labeled “1x” means that of the total quakes of 5,464 – 4,476 days saw a single earthquake. A total of 733 days saw two quakes, 155 days saw three tremors, 42 days saw four quakes, nine days saw five quakes, two days saw six quakes, etc. Not shown was March 11, 2011, the Japanese mega-quake and tsunami, which saw a total of 42 quakes larger than 6.0 magnitude in a single day.
The most recent example of this multiple quakes per day phenomenon >= 6; occurred on Feb. 6, 2013 when six quakes, including one a very powerful 8.0 magnitude struck in the Solomon/Santa Cruz Islands region; killing at least nine and generating a one and one-half meter tsunami (five feet). Five feet doesn’t seem like a very big wave, however, the nature of a tsunami is very different than a normal wave in that there is a significant amount of water behind a tsunami; which pushes everything down in its path with tremendous force.
My forecast for Feb. 14/15, 2013 of seven quakes in one day in the Santiago, Chile region is not unprecedented. The chart shows that there were three occasions in which this type of event already occurred.
In just the first nine days of February 2013, we saw three days which had two quakes (2x – Feb. 2nd, 8th & 9th), two days which had three quakes (3x – Feb. 1st & 7th) and one which had six (6x – Feb. 6th). Notice from the graph that a six earthquake day has occurred twice. One on Feb. 6, 2013 and the other was on Sept. 20, 1999 in west central Taiwan as follows: 6.4 – 6.8 – 6.1 – 6.6 – 6.3 – 7.7. The 7.7 magnitude quake killed 2,415 people, injured 11,305, and saw NT$300 billion (US$10 billion) worth of damage. It was the second-deadliest quake in the recorded history of Taiwan, after the 1935 Hsinchu-Taichung earthquake.
For all of January 2013 we had a total of six earthquakes >= 6.0 magnitude. February 2013 saw 18 and we are only about one-third through the month. Of those 18 quakes, 16 were located in the Solomon/Santa Cruz Islands region, one was in Japan (Feb. 2 – 6.9) and one was in Colombia (Feb. 9 – 6.9).
