A humpback whale. The songs of fin whales can be used for seismic imaging of the oceanic crust, providing scientists a novel alternative to conventional surveying, a new study published this week in Science shows. Fin whale songs contain signals that are reflected and refracted within the crust, including the sediment and […]

Mead crater, the largest impact basin on Venus, is encircled by two rocky rings, which provide valuable information about the planet’s lithosphere. Credit: NASA At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 […]

39 Ocean Bottom Seismometers were deployed on the ocean floor across the Mid-Atlantic Ridge as part of the PI-LAB experiment.

Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years. The last gigantic blast occurred in 1964, creating a new crater and covering an area of nearly 100 square kilometers with pyroclastic flows. But Shiveluch is actually currently erupting, as it has been for over 20 […]

A 2019 eruption of Steamboat Geyser in the Norris Geyser Basin of Yellowstone National Park. The geyser’s first documented activity was in 1878, and it has turned off and on sporadically since, once going for 50 years without erupting. In 2018 it reactivated after a three-and-a-half-year hiatus, for reasons that […]

Overview of the study area and the schematic illustration of interaction of fault motion and the seafloor subsidence. Credit: University of Tsukuba University of Tsukuba researchers have developed a state-of-the-art model, which has revealed major complexity in rupture processes even in simple oceanic faults. Researchers from the University of Tsukuba […]

A seismic station on the Greenland Ice Sheet installed by authors. Snow accumulation in one year is ~1.5 m, and the solar panels are buried in the snow. Snow removal and maintenance are done manually by several people. Credit: Genti Toyokuni A team of researchers understands more about the melting […]

Map of the Cascadia subduction zone. Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia — Vancouver Island, Canada, to northern California — are some of the most severe natural disasters in the world. Now a team of geoscientists thinks the key to understanding some of these […]

ANIMATION Australia’s east coast is littered with the remnants of hundreds of volcanoes — the most recent just a few thousand years old — and scientists have been at a loss to explain why so many eruptions have occurred over the past 80 million years. Now, geoscientists at the University […]
