obtain and view seismic data from IRIS
This is deteriorating from a pedagogical tool to a storage place for cryptic notes. But, better than nothing.
One way to get some seismic data from IRIS and look at it
1. Use the GMAP (google map) interface on the IRIS site
http://www.iris.washington.edu/gmap/
The instructions tell you what to enter in the URL
lat/lon example:
http://www.iris.edu/gmap/?minlat=46&maxlat=49&minlon=-125&maxlon=-
