On March 31, 2002 a powerful earthquake in the Taiwan area reportedly produced hundreds of injuries and a number of fatalities. The following is some information regarding precursor data which were collected during the days before that earthquake occurred.

This following March 24 report pointed out that a strong geomagnetic storm had just occurred after there had been a warning signal quiet period:

And the following March 29 report stated that warning signal data were being collected at a greater than usual rate:

The most warning signal data were collected on March 30. And after the Taiwan earthquake occurred on March 31 signal activity almost completely stopped.

At this time I do not know exactly what causes this to happen. But, before many earthquakes like that, numerous data points may be collected which appear to point to fault zones around the world. And I often have to use a variety of data evaluation procedures in an effort to determine where the earthquake which is actually responsible for all of that precursor activity might be about to occur.

With that Taiwan earthquake none of my present data evaluation procedures worked. I might have been able to identify the approach of a western Pacific Ocean earthquake and one in Asia. But my evaluation procedures are not yet sophisticated enough to generate accurate location data for some earthquakes. And that was the case here.

Some of my latest precursor data appear to have been good matches for that powerful April 1, 2002 earthquake in Chile.

These are my own opinions.
