The Kinemetrics EpiSensor force-balanced accelerometer is a uniaxial surface package designed primarily for structural engineering applications. However, it can be used in a variety of applications for measuring accelerations up to ±4g and down to the ambient noise level. With full-scale recording ranges of ± 0.25 to ± 4g (user selectable) the EpiSensor provides on-scale recording of earthquake motions even at near-fault locations and in a wide variety of structure types.

One of the worst things that can happen during a deployment, especially a highly remote deployment, is not having the correct tools or supplies.  The following is a minimum suggested list of things to take if you are constructing a station that will house PASSCAL equipment for more than a few weeks. This list is in addition to the construction materials that will be used to make vaults, enclosures and fences.  Usually this would pertain to passive-source, broadband (or midband) experiments that deploy equipment for 1-2 years and will be visited approximately every three months during that time in order to check the data and the condition of the station.  PASSCAL will advise if any other specialty tools are required.  Please adjust quantities to provide for all installation teams and number of stations.

PASSCAL provides open-source software for downloading seismic data from data recorders, for quality assessment, and for conversion to other data formats for analysis and archiving at the IRIS Data Management Center.

PASSOFT is supported only for Mac and Linux operating systems, and not for Windows. Some Windows users have been able to use PASSOFT by first installing a Windows Subsystem for Linux.

Note - Python: We no longer support Python version lower than 3.9.
