A new collaborative project will make it possible for scientists to use real-time seismic, weather, and infrasound (sounds below levels that humans can hear) observations to track a suite of phenomena ranging from earthquakes to wildfires to sea i
Tsunamis caused by submarine (below water) and subaerial (above the water) landslides are a serious hazard in bays and fjords of coastal Alaska, particularly in Southeast and South-central Alaska.
During 2019-2020, the Alaska Earthquake Center underwent an unprecedented expansion of our permanent seismic monitoring network. We were able to achieve it by acquiring 96 of 158 temporary USArray sites in Alaska.
On October 19, 2020 a magnitude 7.6 earthquake shook the ground in the vicinity of the July 22, 2020 M7.8 Simeonof earthquake aftershock region (Figure 1).
Large earthquakes, like the recent M7.8 in Alaska, can be seen at seismometers around the world! When an earthquake occurs, seismic energy travels in all directions, much like ripples in a pond.
