That one still is "computer generated".  Often, after being reviewed by a
seismologist, the position shifts a little.  Sometimes it shifts a lot; as
much as 10 to 20 miles.  It's interesting, but until it's reviewed I
wouldn't put to much meaning into it.

I didn't bother to link the page yet. Of course, once you post it here,
the google bot indexes it.

The only reason I noticed the quakes is wunderground.com lists them
when you check the weather.

Regarding new imagery, everyone seems to think it is still the old
stuff, so the new copyright from google earth is misleading.
Incidentally, they have version 4 out now. I really don't find it to be
a big improvement. It fills the screen better since the controls are
now hidden in the upper right hand corner.

I noticed some seismic activity tonight in Valencia (ca). ;-)

Getting back to sonic boom induced quakes, it seems to me you could
probably do better with a network of microphones, that is shaking the
earth is secondary. Of course, the geophones have subsonic respone,
while microphones probably crap out at a few Hz. I have some Crown
pressure zone microphones, though no way to connect them to the PC. Eh,
another project. These don't need phantom power (something I'm sure you
are familiar with). Rather they have a small amplifier. Some company
dumped them because they got tired of replacing the batteries in their
video conferencing lab. Crown PCC160.
