Active Message Threads for August 2007
John or Jan Lahr
Seismology Educators,
Robert Butler and I have posted a summary of the recent magnitude 8
event in Peru, including seismograms from three AS-1
instruments. This event was large enough to be well recorded on all
of the educational stations. If you didn't record it, then contact
me so we can work on getting your station working again!
See: http://jclahr.com/science/psn/as1/peru07/index.html
Cheers,
John Lahr

Attached is a slightly revised and more accurate labeling of the WLIN
24-hour seismograph display that I sent earlier. It turns out that the
signals from the M5.8 Andreanof event at about 04:03 on Aug. 16 and the
M5.6 Peru event at about 04:04 on Aug. 16 arrive at the WLIN station at
about the same time. I've changed the label to "Andreanof" because it
is the larger earthquake.

Here are some images of the earthquake activity in the last 24 hours
including a labeled image of the 24 hour seismograph record for the WLIN
AS-1 station. The USGS earthquake site (http://earthquake.usgs.gov) has
information on these events including the loss of life and damage from
the M7.9 Peru earthquake.
