Two new studies investigate activity at Hawaii’s Kīlauea leading up to and following the 2018 eruption to better understand the volcano’s plumbing and behavior.
Insights from a 13-year monitoring program of Sierra Negra—one of the many volcanoes that dot the Galápagos Islands—shed light on the volcanic evolution of basaltic eruption.
Researchers suggest a magma chamber sits within an old submarine caldera structure that extends into the mantle. Nearby, a new underwater volcano emerged with a flurry of seismicity.
Steamboat Geyser, the world’s tallest, is in the midst of one of its largest periods of activity. Is it linked to new magma intruding under the Yellowstone caldera?
Offshore observations by cabled ocean-bottom pressure recorders have revealed details of the 2015 eruption of Axial Seamount submarine volcano in the Pacific Ocean.
Large-volume volcanic eruptions can create instabilities in the ground above magma chambers, leading to massive collapses and telltale calderas.
High-precision airborne measurements, in combination with atmospheric modeling, suggest that the Katla subglacial caldera may be one of the planet’s biggest sources of volcanic carbon dioxide.
A volcanically heated Costa Rican lake hosts only one type of organism, suggesting that its Mars-like environment is just barely capable of supporting life.
Scientists use 3-D imaging to reveal Solfatara crater’s inner plumbing.
A recent volcanic eruption near Tonga in the southwest Pacific created a new island, giving scientists a rare opportunity to explore the volcanic record of this remote region.
