Now that I'm home, I've moved the document describing the M7.7 Chile
earthquake of November 14, 2007, to a more permanent
location: http://jclahr.com/science/psn/as1/index.html#Summary

I've also created a video describing the aftershock sequence from
this event. This was done using the program Camtasia to capture the
sequence as it was being displayed by the Seismic Eruption program:
http://jclahr.com/science/psn/as1/chile07/chile2007/index.html

Based on the extent of the aftershock zone, the mainshock ruptured
from the north to the south-southwest for a distance of about 150
km. At 3 km/second, which is a typical rupture propagation speed,
the mainshock would have lasted 50 seconds.

Cheers,
John
