The clickable names below will take you to the home pages of the authors of the various programs,
some of them are free, others incure a small cost for a registered copy, you sort that out with those
concerned
1)
SEISMIC/ERUPTION This is Alan Jones's latest creation, and is the Windows version of his
earlier DOS based program called " SEISMIC ". It plots earthquake and volcanic activity on beautiful
shaded relief maps covering all parts of the world. You can even create your own custom maps.
2)SDR/WINQUAKE Here you will find Larry Cochranes contributions
to the software world. One program for data logging.... " SDR "(Seismic Data Recorder) and another
for data analysis.... " WINQUAKE " both are excellent and are in wide use by amateur seismologists
who are doing recording of quakes from home and schools. The Winquake program will display files from
SDR and from the USGS system and with it you are able to identify the various phases, determine the
distance to and the magnitude of the quake.
3)SEISMIC WAVES This is another
brilliant program from the keyboard of Alan Jones. This program shows the propagation of seismic
waves across the earth's surface and through the earth. It shows the refraction, reflection and
the creation of the different phases within the earth. It uses real quakes and displays the seismograms
of those events recorded at various stations.
I'm sure that there are other packages out there....
If you know of any, e-mail me and let me know what they are about, thanks.
University of Nevada, Reno, Nevada The top drum is connected to a vertical sensor
and it records the big distant events really well, check this one first for confirmation of a big
event you recorded. The view is automatically updated every minute for those using Netscape
A selection of short period sensors from around New Zealand This display is operated by the GNS (the NZ Seismological
Observatory) and updates every 5 minutes. The display shows last 4 hrs of data. clicking on a dot on the map to the left
will show the previous 24 hrs of recording for the selected station.
From the USGS This site gives access to many of the LP recorders that make up the WWSSN stations
in many different countries. It is updated every 30 minutes and the display shows last 24 hrs of data.
Other Public Seismic Network (PSN) and members of, Homepages
Redwood City Public Seismic Network, in California
Larry Cochrane has an amazing digital seismic recording system, and via his PSN e-mail list
server, all us fanatical and not quite so nutty amateur seismologists can keep in touch with
each other, swapping construction ideas etc.
Alaska Public Seismic Network, This is run by Bob Hammond and he has worked hard to get practical seismology into schools
PSN San Jose, California, This is run by Steve Hammond. The main focus of this PSN site is on
the Lehman seismograph, the history, and the people that make up the PSN. Feel free to send me
an electronic photo to put on the "PSN WALL" that tells the PSN story.
