Seismology Coordination

Scientific Motivation and Response Planning

Determine scientific goals for post earthquake deployments depending on the location and type of earthquake. Some examples:

  • Capture a large aftershock to examine detailed rupture properties
  • Improve aftershock locations to better understand relationships between co-seismic slip distribution and aftershock occurrence
  • High resolution mapping of ground motion related to site response and seismic hazard
  • Map fault damage zones and healing

Management and coordination of post earthquake seismic array deployment:

  • Assess the instrumentation needs based on the priority seismic study
  • Coordinate field teams with instrumentation based on location of event and science priorities
  • Data collected by the SCEC ommunity during a rapid response deployment should be made available as soon as possible. If available, telemetry should be used to send seismic data in real time to SCSN

In addition to the SCEC PBIC and PASSCAL RAMP programs, other investigators and agencies in California have access to portable equipment for use during post-earthquake response activities. These groups are listed in the link below. If your not on this list but have equipment that may be available after an eartquake, please add yourself to this wiki page.

See list of available seismic instruments.

ShakeOut 2008

The Seismology Group used the 2008 ShakeOut to improve earthquake reqpsonse. 

The report attached below describes the deployment and issues related to real-time telemetry back to the SCSN.

Portable Deployment ShakeOut Response

PBIC and IRIS portable stations were deployed for ShakeOut. A single station was deployed along the SoSAF at Indio, and a fault crossing array was deployed at whitewater canyon. 2 PBIC stations and 5 IRIS stations are connected via cell modem back to CISN Caltech/Pasadena and provide real-time data feed to the network. See the attached report below.
