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?
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.
Evidence collected following the 2011 eruption of Japan’s Shinmoedake volcano suggests that the powerful event affected the behavior of an active caldera nearby.
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.
A network of buoys provides a first glimpse of the seafloor beneath a volatile Italian caldera.
Scientists use 3-D imaging to reveal Solfatara crater’s inner plumbing.
