Alaska Secures First Federal Funding to Bring ShakeAlert Earthquake Early Warning System North
Congress allocates $2 million from the USGS ShakeAlert budget to begin building Alaska's first earthquake early warning system, targeting 90 percent of the state's population.
Overview
Congress has allocated $2 million to begin extending the ShakeAlert earthquake early warning system to Alaska, marking the first time federal funds have been directed toward bringing the technology to the most seismically active state in the United States. The allocation, drawn from a $34.9 million USGS ShakeAlert budget, will fund the initial implementation steps of a system that currently operates only in California, Oregon, and Washington, where it serves over 50 million residents, according to Early Warning Labs.
The effort is being led by the Alaska Earthquake Center at the University of Alaska Fairbanks, in partnership with the USGS. Full implementation is estimated to take approximately six years and cost roughly $66 million, with $12 million in annual operating costs thereafter, according to the UAF Geophysical Institute.
What We Know
ShakeAlert works by detecting fast-moving primary waves (P-waves) that precede the slower, more destructive secondary waves (S-waves), giving recipients a warning window ranging from a few seconds to over a minute depending on earthquake type and distance from the epicenter, as KTUU reported.
The USGS published a Phase 1 technical implementation plan in February 2025 that outlines the scope of the Alaska expansion. The plan calls for a network of 450 real-time seismic stations: 270 new installations, 160 upgrades to existing stations, and 20 stations already in place, according to the UAF Geophysical Institute. Station spacing would range from 10 kilometers in urban areas to 40 kilometers in less populated zones. The network would also include GNSS stations to improve detection of subduction zone earthquakes.
The initial rollout will target Anchorage, Fairbanks, Kodiak, and the Prince William Sound region, areas that together contain approximately 90 percent of Alaska’s population and combine high seismic hazard with existing monitoring infrastructure. Two geographically separated data centers in Alaska would process sensor data and distribute alerts, mirroring the architecture used on the West Coast.
Senator Lisa Murkowski, who helped secure the appropriation through the Senate Appropriations Committee, stated that expanding ShakeAlert into Alaska is a priority. “When earthquakes hit, seconds matter. The ShakeAlert Earthquake Early Warning System provides lifesaving tools,” she said, as quoted by the UAF Geophysical Institute.
Michael West, Alaska’s state seismologist and director of the Alaska Earthquake Center, called the funding “outstanding news for Alaska” and described the moment as a turning point after more than a decade of advocacy. “There’s a lot to figure out. But I feel like we’re at a turning point. We’re starting to make this real,” West told Alaska Public Media.
Alaska’s Unique Seismic Challenges
Alaska presents engineering challenges that distinguish it from the existing West Coast ShakeAlert deployment. The state experiences three distinct types of earthquakes: shallow events along mainland faults, deep subduction zone events at 50 to 200 kilometers depth, and massive offshore quakes that can reach magnitude 8.0 to 9.0, according to KTUU. The 1964 Great Alaska Earthquake, a magnitude 9.2 event, remains the most powerful earthquake recorded in North American history.
Ronni Grapenthin, a UAF professor involved in the project, framed the work as fundamentally an engineering challenge. “Earthquake early warning is predominantly an engineering problem. We take what we can learn about earthquakes, and we try to speed it up,” he said, as reported by the UAF Geophysical Institute.
Japan, which operates the world’s most advanced earthquake early warning system and faces a comparable range of seismic event types, provides the closest operational parallel for what Alaska aims to build, as noted by KTUU.
What We Don’t Know
The $2 million allocation represents a small fraction of the estimated $66 million needed for full Phase 1 implementation. Whether Congress will continue to fund the project at the levels required to meet the six-year timeline remains uncertain. West acknowledged to Alaska Public Media that the system is still “several years and many millions of dollars away” from becoming operational.
The system’s effectiveness in Alaska’s vast and sparsely instrumented terrain is also an open question. Much of the state lacks the dense sensor coverage that enables sub-second alert generation on the West Coast. How quickly the network can be built out in remote areas with limited infrastructure and extreme weather conditions will shape the timeline.
Beyond the hardware, West emphasized to Early Warning Labs that public readiness is equally important: “The technology is only useful if the people and systems on the receiving end are ready to act on it.” The implementation plan includes a public education component, but the scope and funding for that effort have not been detailed.
Automated Response Potential
On the West Coast, ShakeAlert has been integrated into automated systems that can open fire station bay doors, pause surgical procedures, shut off gas valves, and trigger occupant alerts during the 5-to-60-second warning window, according to Early Warning Labs. Whether similar integrations will be pursued in Alaska from the outset or added incrementally has not been specified.
