Supersharp Images Reveal Scars of Major Eruption on Io
Jupiter’s volcanic moon is captured in exquisite detail by an instrument atop a mountain in Arizona.
Caldera Collapse as a Natural Example of Rock Friction
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.
A Magnetic Low May Have Paved the Way for Complex Life
Multicellular life blossomed when Earth’s magnetic field was at an all-time low.
A Magma Ocean Fuels This Exoplanet’s Atmosphere
The finding is an atmospheric first for astronomers but not for the planet.
The Moon’s Mantle Did a Flip—and Scientists May Now Have Evidence
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
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
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.
Icelandic Fissure Finally Erupts
The position of the eruption and wind conditions are favorable. No one is in immediate danger, local officials said.
