From the Maryland Science Center ...
I have a more general question about quakes that I hope one of the
experts can help me with. We have been using a machine to simulate
earthquakes that ostensibly varies magnitude - Pitsco's Epicenter
Earthquake Simulator. They no longer make this and now sell instead the
EQ Tremor Table
<http://catalog.pitsco.com/store/detail.aspx?KeyWords=engineering&by=20&ID=4229&c=0&t=0&l=0>,
which, instead of magnitude, varies cycles per second (frequency), from …

IRIS is now accepting applications for the Seismographs in Schools
Program for 2008. For details, see:

Paul Denton of the British Geological Survey has compiled a good
review of school seismology and posted it
here: http://www.bgs.ac.uk/scripts/downloads/start.cfm?id=667
I highly recommend taking a look at his report, titled "School
Seismology Support Documents."
Cheers,
John

Hello, Lindsay,
I used to be the person responsible for the AS-1 Seismograph at Montgomery
High School. However, I have left the school, and now Tim Murphy, the
Science Dept. Chairman, will be taking over responsibility.
I would like to unsubscribe from the IRISEd mailing list. I would
appreciate it if you would add Mr. Murphy to the list in my place. His
email address is

Educators,
The west coast of North America has been active lately. There was
another event on the Queen Charlotte Islands fault on January 9th and
a magnitude 6.4 event on the Blanco Fracture Zone on the 10th.
Professor Robert Butler generated this writeup, to which I added my
CHOR record:

The two M6.5 earthquakes of 1/5/2008 on the Queen Charlotte Islands
Fault were well recorded by AS-1 stations all across the US. I've
posted some information from Robert Butler, along with two seismograms.

Just after the November 14, 2007 M7.7 N. Chile Earthquake I noticed an
unusual high-frequency arrival overlapping the long period surface waves
on the seismogram for this event that was recorded on the WLIN AS-1
station. I high-pass filtered the seismogram and assumed that the
resulting arrival was from an aftershock about 29 minutes after the main
shock. I checked with the USGS earthquake list for the next few days
and didn't find an aftershock at the appropriate time so I looked for
