Large earthquake on the Pacific Antarctic Ridge
Posted by Lowell on August 05, 2001 at 22:03:25:

A large earthquake is being reported from the Antarctic-Pacific Ridge
by NEIS. Initial reports put the Mb at about 6.0, but the Mw looks larger
than Mw 6.3 from initial seismogram readings. The initial epicenter
of the event is 55.7S 123.1W. For details see:

Seismograms can be seen at:

So, why should the readers of this board be interested in an event
so far away which will affect no one but a few whales?

On July 18, 2001, Don posted what I considered an outlandish,
and probably untestable prediction for this region as follows:

Pacific-Antarctic Ridge Forecast
Posted by Don in Hollister on July 18, 2001 at 00:40:44:

Magnitude: 4.0-5.3Md
From: 07/20/2001PST - To: 07/25/2001
Location: Pacific-Antarctic Ridge
Lat: 56.2S - Long: 122.4W - Range: 40Km

This prediction suggests a moderate event within 12 days of the
event that occurred today. The epicenter is probably within 50-60 km
of his prediction (current epicenter is quite preliminary and will
change with time).

If the initial magnitude is slightly low, this will be the
largest event in this area (within 200 km) since April 4, 1971 (more
than 30 years ago). To be able to predict such an event within
two weeks is quite an accomplishment.

I will post a complete evaluation when the epicenter and magnitude
have been more precisely determined.

Don must have added some whale blubber to his menu that night.
But I think we should be more than a little curious why Don
chose this location of all the places on earth where a Ms>=6
could occur.
