Instruments typically used to detect the ground motion of earthquakes can also be used to identify the type of aircraft flying far overhead, research by University of Alaska Fairbanks scientists shows. That’s because aircraft sound waves also shake the ground, although to a much lesser extent. An aircraft’s type — a Cessna 185 Skywagon, for […]
The Pacific Northwest boasts an extensive network of more than 600 seismic monitoring stations that help researchers track tectonic and volcanic phenomena, including earthquakes. This data provides key insights into regional faults and feeds into early warning systems, which can give a community precious moments to prepare before a natural disaster strikes. A significant threat […]
Mount Edgecumbe volcano in Southeast Alaska has become the latest addition to the Alaska Volcano Observatory’s ground-based monitoring network. An observatory team in early September installed three seismic and Global Navigation Satellite System stations on the reawakened volcano and upgraded the only existing station in the vicinity, a temporary one on nearby Crater Ridge. “This […]
Earth has earthquakes, Venus has venusquakes. Researchers at the University of Alaska Fairbanks Geophysical Institute, working with NASA, are helping create a Venusian seismometer that can operate long enough in that planet’s extremes to provide insight into its seismicity. It’s a major challenge. Venus has surface temperatures of 900 degrees Fahrenheit, hot enough to melt […]
