I have now found three more examples of destructive earthquake pairs which show how this newly developed wave chart technology might have been used to help forecast the second destructive one in each pair had it been available at the time.

Two of the earthquakes occurred in El Salvador in 2001. The other four occurred in India in 1993 and 2001. That new information has now been added to my 90-03c.gif file. But the expanded file itself will probably not be stored at my Web site for a few more hours because I want to update the text in the associated .html Web pages.
