ANCHORAGE, Alaska (Nov. 18, 2025) —The Alaska Earthquake Center recorded about 400 small earthquakes across the state this week, with only three reports of shaking felt by residents. The most significant event was a magnitude 4.4 earthquake south of Chignik on November 12.
Alongside the routine seismic activity, the Earthquake Center says it is in the middle of a significant internal upgrade, A change most Alaskans won’t see directly, but one that will strengthen how the state’s earthquake data is processed and delivered.

For the past year and a half, the team has been building a new system to manage and analyze earthquake data, designed to improve long-term reliability and prepare for future technologies, including artificial intelligence.
Reliability is a key priority for the center, especially during major earthquakes and tsunamis when communications networks can be disrupted. To address this, the new system will run in two locations: one at the Earthquake Center and another on an out-of-state cloud platform, helping ensure operations continue even if local infrastructure is affected.
AI tools are still being developed, but the center has already adopted software that makes it easier to move new research methods into daily operations. These improvements will support ongoing work to better understand major fault systems, refine seismic hazard information, and lay the groundwork for eventual earthquake early warning in Alaska.
