Lake-ice quakes observed at Newberry Volcano
Aided by record-setting subfreezing temperatures, the popping and cracking of ice in the caldera's lakes is picked up by local seismic stations.
This season's first lake-ice quakes are occurring at Newberry Volcano. The lake-ice quakes do not resemble standard volcanic low-frequency or high-frequency events and are sporadically observed in the winter at ice-covered lakes in Yellowstone, Long Valley, and elsewhere. Ice quakes were first noticed at Newberry in December 2011, after the new seismic network was installed. The sensitive network was designed to detect earthquakes and other seismicity that occur beneath the Newberry Volcano and has also provided insight into the way sound travels through the upper crust in the area.
