New Madrid Quakes - nearly 2,000 in 90 days!

[Guest guest]

Therese,

 

You may want to look at your various charts for these quakes. Four of

the five, or possibly five of six, of the largest earthquakes to

occur in the contiguous United States since its settlement occurred

in this region in a timespan of 53 days.

 

Here is a link.

 

http://neic.usgs.gov/neis/eq_depot/usa/1811-1812.html#december_16

 

And here is a quote from that page:

 

" Otto Nuttli reported that more than 200 moderate to large

earthquakes occurred on the New Madrid fault between December 16,

1811, and March 15, 1812 (5 of MS about 7.7; 10 of MS about 6.7; 35

of MS about 5.9; 65 of MS about 5.3; and 89 of Ms about 4.3). Nuttli

also noted that about 1,800 earthquakes of mb about 3.0 to 4.5

occurred in that same period. "

 

That is an average of more than 20 earthquakes a day for the 90 day

period and an average of 2 moderate to large earthquakes each day for

the same period of time!
