Does anyone have a current address for Al Allworth? My message to
him bounced back:
Unknown user: Allworth@..............
NAME: Al Allworth W7PXX
TOWN/CITY: Gold Beach
LAT./LONG: 42.51N 124.33W
CH1: COM; Mark Products 1 Hz model L-4.
GROUND TYPE: located .5 mile from the Pacific Ocean on bedrock of
Jurassic age, composed of
sedimentary and volcanic deposits. Very close to
alluvial deposits of sand, gravel
and silt. I see a lot of motion from wave action.
I was thinking about getting the Oregon PSN members together for an
informal meeting some time. Gold Hill is quite a distance from
Corvallis and Salem, where Robert L. Laney, Steve Clark, and I
live. Do you ever have occasion to get up this way? We could try to
schedule something around a trip that you're making anyway.
When I was running the seismograph network in southern Alaska for the
USGS we used L4 1 Hz seismometers. They were very reliable and just
right for local and regional events. It took a really large
magnitude to see any surface waves from a distant event, however. Of
course from our point of view, this was just noise!
