Stations of the Pacific Northwest Seismic Network (PNSN) showing current short period stations (crosses) and U.S. National Seismic Network (USNSN) broadband stations (yellow and blue triangles). The stations shown as red triangles will be transferred from the Transportable Array to the PNSN at the completion of the normal Transportable Array operating period in 2007. Funds provided by the Murdock Foundation will be used to replace the Transportable Array equipment and ongoing operational support will be provided by the USGS. Negotiations are underway for the additional stations shown as white triangles to be transferred with support from Battelle.
