Alaska's seismic stations dimmed, jeopardizing U.S. tsunami warning efforts.

Nine seismic stations in Alaska will cease operations this month, undermining the U.S. tsunami warning system critical for predicting tsunami threats from earthquakes.

• The shutdown of nine seismic stations in Alaska this month threatens to disrupt the tsunami warning system, crucial for monitoring seismic activity along the Alaskan Subduction Zone.
• Federal funding for the seismic stations lapsed last year, and the Trump administration chose not to renew the grant, impacting data collection vital for tsunami forecasting.
• Data from these stations informs the National Oceanic and Atmospheric Administration on earthquake magnitude, directly influencing tsunami risk assessments for coastal areas including Washington (state) and Hawaii.
