⚠️ WARNING: Maintenance on Sep. 3rd at 10AM MT

This website will be going down for approximately 2 hours starting at 10AM MT on 9/3/2026 to be moved to a new location. In the future please use http://epic.earthscope.org to reach this website (do NOT use http://www.passcal.nmt.edu)

Here are some of the articles that have been recently posted to the PASSCAL website:

Instrumentation

​​

Instrumentation to support portable seismology available from the EPIC:

Dataloggers - This section encompasses the equipment which take in data and stores it on some type of non-volatile media.

Power Systems - All the required equipment to keep a seismic station continuously powered throughout its deployment.

Sensors - The equipment that actually detects and quantifies ground motion. The sensor sends this information to the datalogger through a cable.

Electrical Resistivity Tomography (ERT) Systems

EPIC currently has two SuperSting R8 systems from Advanced Geosciences, Inc for electrical resistivity tomography (ERT) studies.

Available sets of cables include: one set of 56-electrodes at 2-meter spacing, and one set of 112-electrodes at 6-meter spacing.

Passive Source (SEED) Archiving Documentation

Main Documentation for PASSIVE Source Data Processing (SEED)

The documentation below offers instructions for archiving data from EPIC instrumentation in miniSEED format with metadata to be submitted as stationXML. To archive data from a EPIC experiment, select the appropriate documentation for your instrument for instructions for preparing the data before transferring it to EPIC. For the metadata, EPIC offers software for generating stationXML for your experiment. Please see the documentation for metadata generation using Nexus.

For EPIC PIs who previously archived data using Antelope, our documentation has been reworked to generate metadata in stationXML format via the EPIC program Nexus rather than using an Antelope database to create a dataless SEED. The documentation for archiving data with Antelope is still available on this page.
