Waveform Data

There are ways to obtain ground motion records or images of the seismic traces from our network data that we record and archive.

PNSN Seismograms. Images of current and archived ground motion for nearly all PNSN and contributing network channels.


Strong Motion Center [straightforward interface to strong motion data, but only for our largest earthquakes]


 IRIS DMC Archive [complete data archive, but a bit complicated and using a variety of request methods, the following links are some good starting points] 

• To use IRIS to view all stations that have operated in the PNSN network region, start here: http://www.iris.edu/gmap/?minlat=42&maxlat=49&minlon=-127&maxlon=-117

• For access to realtime data from IRIS, please start here: http://www.iris.edu/data/bud/#real

• For access to historic (archived back to 1980) data from IRIS, start here: http://www.iris.edu/SeismiQuery/breq_fast.phtml

• And, for access to webservice data access at IRIS, (http:port80 access) start here: http://www.iris.edu/ws/
