FDSN code XN (2000-2002) Network name Parkfield Passive Seismic Array (PASO)
Start year 2000 Operated by

End year 2002 Deployment region

A temporary seismic array, known as PASO (Parkfield Area Seismic Observatory), was installed in stages, starting in July 2000. Initially, 15 PASSCAL instruments were deployed around Parkfield, CA, in stand-alone mode, with 3-component short-period sensors (1 Hz HS-10s). In October 2000, 14 of the 15 sites were converted to real-time telemetry. In June and July of 2001, the 15-station array was augmented by the installation of 44 additional PASSCAL 3-component stations within the aperture of the original array, and 2 of the original stations were moved. Most of the new sites were installed with broadband sensors (29 Guralp 40Ts and 7 Streckeisen STS-2s). (see notes section for more)
