Amateur Radio Public Seismic Network

NOTE 202109.21: Due to fire & floods there is no "Current Seismicity".
I am attempting to rebuild another PSN from the pieces I have left.

The original Redwood City PSN is now located at:

PSN Heliplots can be observed here:

Adobe; without regard to anyone's work or content, scuttled FLASH!
I am working on a fix to replace all ARPSN Flash Animation; if possible.

During 1997 I started to construct a PSN seismic station and got as far as building a 'seismic shed' with a large poured concrete block as a base and collecting some of the equipment, before I was diverted.

This will be my second attempt to complete this project, with hopes of adding some current technology and creating an Amateur Radio Public Seismic Network.

White Paper being prepared.

ARPSN is dedicated to Larry Cochrane for his contribution to Public Seismic Network (PSN) and Dr. Hank Magnuski, KA6M, for his contribution to amateur packet radio and Pacific Packet Radio Society PPRS.
