Hi Roger,

It looks like about the most global earthquakes that my program might be able to work with with for the 1990 to the present range are ones around 4.5 magnitude and up. There appear to be something like 100,000 of them.

This is going to require some thought regarding the best course of action to take.

On another note,

People checking Chart-A on my Data.html Web page as shown below will see that recent EM Signals are showing strong line peaks in the 140E to 143E longitude area. And that matches with the 6 and higher magnitude earthquakes that are occurring almost daily in the Japan area.

Remember that this chart will change as newer versions are stored on my Web site.

I am still in the process of trying to interpret the EM Signal and chart data associated with the March 11, 2011 9.0 magniutde earthquake in Japan. That earthquake can be seen on the April 23, 2011 Chart-A as a large red circle.
