Equipment Replacement and Geologic Investigations Related to the Alaska Earthquake

On November 30, 2018, a magnitude 7.1 earthquake caused widespread damage to infrastructure and property in the Anchorage area.

  • The USGS will harden the Alaska Volcano Observatory (AVO) network instrumentation and repair facility damages and telecommunications equipment to reduce the vulnerability of the AVO from future natural disasters and maintain its capabilities to monitor Alaskan volcanoes and warn of volcanic activity.
  • The USGS will deliver post-earthquake investigations under the National Earthquake Hazards Reduction Program to support future earthquake hazard response and risk reduction by emergency managers and State and local governments. These will include descriptions of seismological characteristics of the earthquake and associated ground failure and investigations of building and civil infrastructure performance.
