Project Highlights 2002 - Denali Earthquake Emergency Response

Denali Earthquake Emergency Response

  • Principal Investigator (PI): Jeff Freymueller (U. Alaska Fairbanks), Tom Murray (USGS)
  • UNAVCO Engineers: Jay Sklar, Bjorn Johns, Jim Greenberg
  • Dates: November 5, 2002
  • Location: Fairbanks, Alaska.

The UNAVCO Facility has completed an initial emergency response to the November 3 magnitude 7.9 earthquake on the Denali Fault in the Alaska Range. Four campaign receivers from the UNAVCO pool were deployed by University of Alaska, Fairbanks (Jeff Freymueller, PI) staff two days after the quake. A UNAVCO field team also installed 10 semi-permanent continuous stations during the first two weeks after the earthquake. These stations used Ashtech uZ and Trimble 5700 receivers, and tall antenna mounts to keep clear of snow accumulation. Due to the dark northern winter, power is solely from rechargeable batteries that will be swapped during periodic service visits. Longer lasting air-cell batteries are already slated for the most remote sites. Data retrieval is from manual data downloads or memory card swap, as most sites are in locations with no local communications infrastructure. Upon retrieval, the data will be made publicly available in the UNAVCO archive. Further densification, fortification, and power upgrades (solar and possibly wind turbines) of exisiting sites will occur summer 2003
