UNAVCO Hosts Workshop for Undergraduate Reserach Internship Leaders

Workshop Goals

Leaders of NSF-funded internship programs (called "Research Experiences for Undergraduates" (REUs)) in the Geosciences Directorate gathered together in San Jose on October 26th and 27th, 2011, for a workshop. The goals of the workshop were to support:

  • Community building among REUs,
  • Sharing ideas, learning strategies, and working on your program plan,
  • Exchaning ideas on recruiting and supporting diverse students,
  • Participating in the SACNAS conference after the workshop,
  • Identifying tools for enhancing communication and networking
    between REUs.
  • We hope that you will join us and take advantage of this opportunity to network with other REU Principal Investigators, learn new strategies, and more.

    Topics of Discussion

    UNAVCO stands ready to support responses to this event. Current actions include:

    • Recent satellite SAR (ENVISAT) data acquisitions have been confirmed and future acquisitions (ENVISAT and TerraSAR-X) have been requested covering the region near the epicenter. WInSAR users will have access to ENVISAT data. Detailed information will be posted in the forums.
    • Campaign GPS systems are field-ready and on standby for deployment if requested.
    • Plans for possible PBO permanent GPS sites are in development.
    • It has been determined that there is no surface expression of the fault rupture visible around the epicenter. Structural damage is reported mostly for brick buildings, but no rupture. Based on this information, there are no current plans to collect TLS data near the epicenter.

    In response to this event, community members are welcome to request support from UNAVCO. Please visit the Community Geophysical Event Response Coordination page.

    Tectonic Setting: East Coast Tremors

    Earthquakes in the central and eastern U.S., although less frequent than in the western U.S., are typically felt over a much broader region. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast. A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as 100 km (60 mi) from where it occurred, and it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake usually can be felt as far as 500 km (300 mi) from where it occurred, and sometimes causes damage as far away as 40 km (25 mi). (USGS)

    U.S. Geological Survey seismologist Susan Hough notes that, "The waves are able to reverberate and travel pretty happily out for miles."

Figure 1 - Map of Envisat ASAR scenes ordered by UNAVCO. The pair of frames in the southeast are centered over the epicenter, and the northwestern footprint shows the location of the one pre-event scene available, acquired by European Space Agency July 6 and now available in the WInSAR archive. Scenes will be acquired September-December to look for post-seismic changes. These scenes are synthetic aperture radar, and can be used to derive precise topographic maps and detect changes in topography. Images to come from Synthetic Aperture Radar (SAR), a powerful remote sensing system, enabling observations of the Earth’s surface day or night, in all weather conditions from airborne platforms and from space.
