This is from the NEIC: 5.5 Magnitude earthquake at 23:21 on 8th May
2008.
!8 hours since the last one, therefore a storm brewing maybe. It is
certainly heading that way.
From NEIC, based on the ~1500 M5+ earthquakes per year, there are about
480 M5.5+ earthquakes per year, or about 1 every 18 hours. (There have
been 43 5.5 or larger quakes in the last 30 days.)
What did you make of the facts I pointed out to you earlier? A series
of years with less than 8 quakes of 7 M and over per annum.
I made of it that you didn't know how to do the search on the NEIC
website. The NOAA catalog of significant earthquakes, which is what you
searched, has less than half of the earthquakes that the NEIC database
has. For 1990-2, from your search, NOAA had 9, 6, and 13, respectively.
Searching the NEIC database gives 18, 18, and 24. If you had looked at
"USGS/NEIC (PDE) 1973 - Present", instead of "Significant Worldwide
Earthquakes (2150 B.C. - 1994 A.D.)", you'd have gotten a very different
answer.
