In Rare Opportunity, Researchers Observe Formation of Icelandic Valleys

Sarah Stanley, Science Writer by Sarah Stanley 7 August 20249 September 2024

During the lead-up to recent volcanic eruptions near the city of Grindavík, scientists documented graben formation in real time.

Lunar Lava Tube Revealed Beneath Collapsed Pit

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 2 August 20242 August 2024

The Sea of Tranquility is home to at least one lunar lava tube, which could preserve a pristine and unweathered record of lunar volcanism.

How Liquid Is That Lava?

by Rebecca Owen 12 July 202419 August 2024

A new device helps scientists measure lava viscosity during active flows.

A mostly rectangular, man-made structure several stories tall sits among trees along a mountain ridge, against a dim sky. The structure is mostly white colored and has two large, round telescope dishes nested in between taller sections of the building and angled skyward.

Caldera Collapse as a Natural Example of Rock Friction

by Yosuke Aoki 25 June 202424 June 2024

Recurrent slips on the caldera wall of the Kīlauea Volcano are a natural experiment not only to understand the mechanics of caldera formation but also to gain more insights into fault friction.

The Moon’s Mantle Did a Flip—and Scientists May Now Have Evidence

Javier Barbuzano, Science Writer by Javier Barbuzano 8 May 20248 May 2024

For decades, a lunar whodunit has puzzled scientists: Did the Moon’s internal layers flip during its formation? Old data might hold the evidence to solve this cold case.

A Strong Pacific Plate Bends Under the Hawaiian Volcanic Chain

by Emilie Hooft 14 March 202413 March 2024

Two seismic studies reveal the volcanic loads and resulting flexure of the Pacific plate at the Hawaiian Ridge and, surprisingly, show no magmatic underplating.

Iceland’s Recent Eruptions Driven by Tectonic Stress

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 23 February 202423 February 2024

Magma flow in the magmatic dike near Grindavík was among the fastest recorded. The processes driving that flow could be at play at volcanoes in Hawaii, off the African coast, and anywhere crustal plates split apart.
