Geophysical Event Response


The GAGE Facility helps coordinate community field activities, hardware, and data requests following an earthquake or other notable geophysical event. There are two types of event response: Community Events and Data Events. Please see the GAGE Event Response Policy.

Our online discussion forum provides community communication and coordination in response to Community Events. Please use our forum instead of e-mail, so that we can keep communications centralized. If you do not see a Geophysical Event Response listed below and would like to initiate a formal response, email event_responseATunavco.org. A formal full UNAVCO Community Event Response for an event includes having UNAVCO equipment at the ready, gathering high-rate data sets, a discussion forum, and a highlight page showing community effort.

Please Request Support from the GAGE Facility if needed after reviewing the GAGE Event Response Policy.

Acquiring New Data after an Event

In response to an event, community members are welcome to request support from UNAVCO for the following:
  • Campaign GNSS/GPS Systems and/or Field Engineer Support.
  • LiDAR (Terrestrial and Airborne) hardware, data acquisition support and coordination.
  • Coordination of InSAR satellite tasking (under the auspices of WInSAR).
  • Laser Strainmeter, Borehole Strainmeter, Tiltmeter and Borehole Seismometer installations.
  • Planning, permitting and installation of new permanent GPS stations.
  • Education and Outreach Support.
  • General event information.

Relevant Archived Data

The GAGE Facility has data archives (see Related Links at left) for GNSS/GPS data, SAR datasets, and TLS data. GAGE coordinates with OpenTopography to archive ALS data.

The following data may be collected on a per event basis: GNSS/GPS, Borehole Strainmeter, Borehole Seismometer, InSAR, and LiDAR.
