Infrasound data around Alaska, provided by the Alaska Geophysical Network, 2020-present

Since late 2020, over 100 infrasound stations— a legacy of the USArray Transportable Array —have been incorporated into the Alaska Geophysical Network. This regional infrasound network is relatively dense and spans thousands of kilometers, covering a wide range of land cover types across the state from temperate rainforest to exposed tundra. Each station is equipped with a Hyperion IFS-4132 infrasound sensor recording in real time at 40 samples per second and flat from the 10.0 Hz Nyquist frequency down to 0.02 Hz. We acknowledge the Alaska Native nations upon whose land our study area resides and observe the stewardship of the traditional inhabitants of the region.
