Rock Music in Utah
Three-dimensional models could help forecast rock tower frequencies—and seismic impacts—around the globe.
Hundreds of Volcanic Explosions Detected Underwater at Kīlauea
Hundreds of volcanic explosions detected underwater at Kīlauea
The explosions, identified during the 2018 eruption phase, offer a clear acoustic signal that researchers could use to measure ocean properties.
Stratospheric Balloons Listen In on Ground Activity
Solar-powered hot-air balloons, floating 2.5 times as high as Mount Everest, detected a buried explosion more clearly than ground-based sensors did.
Autonomous Vehicles Could Benefit from Nature
A team of researchers at the University of Michigan is looking to animals to find new ways for autonomous vehicles to navigate through the environment.
Earthquake Rupture Solution is Up in the Air
Perhaps the most complex earthquake rupture ever studied is further constrained by signals from Earth’s ionosphere.
A Comprehensive Review of Submarine Volcano Seismoacoustics
Although most of Earth’s lava erupts beneath the oceans, submarine volcanoes are comparatively understudied, but a new review of submarine volcano seismoacoustics provides a framework for future work.
Monitoring Seismic Vibrations During a Pandemic
Researchers in Spain monitored variations in seismic noise across Barcelona as the city locked down during the pandemic, clarifying the seismic band associated with human activity.
Podcast: Songs of the Arches (with Helicopters)
Utah’s famous bridges and spires hum with a deep, earthly music, just below the threshold of human perception.
Earthquakes Reveal How Quickly the Ocean Is Warming
By timing sound waves set in motion by earthquakes, scientists have estimated that the Indian Ocean is warming by roughly 0.044 K per decade.
