A new study published in AGU’s JGR Solid Earth combined the petrological and geochemical data collected in recent decades at Campi Flegrei with numerical simulations, and placed new constraints on the source(s) of the current dynamics of the volcano. The study helps in defining the best monitoring strategies and forecasting a future eruption.
When the Hunga Tonga-Hunga Ha‘apai volcano in Tonga erupted on January 15, 2022, it sent atmospheric shock waves, sonic booms, and tsunami waves around the world. Now, new research published in Geophysical Research Letters shows the effects of the eruption also reached space, causing a major space weather event.
A catastrophic drop in atmospheric ozone layers 60 000 to 100 000 years ago likely contributed to a population bottleneck during that period. According to a new study, the event was triggered by the eruption of the Toba supervolcano in Sumatra, Indonesia. "Toba…
Researchers at NASA’s Jet Propulsion Laboratory in Southern California identified what triggers large-scale volcanic eruptions and the conditions that lead to them. Using data from the 2018 Kilauea eruption in Hawaii– its largest volcanic eruption in over 200…
An international team of researchers published a new study providing new clues about how and where subduction begins on Earth, the process behind the deadliest volcanic eruptions. The Earth's largest earthquakes and most explosive volcanoes occur at subduction…
A new study suggests that the massive Okmok volcano eruption in Alaska in 43 B.C.E. may have caused a nearly two-decade power struggle that led to the fall of the Roman Republic and the rise of the Roman Empire. According to records, the period was marked with…
Steamboat Geyser in Wyoming is the world's tallest active geyser, which sometimes blasts water over 90 m (300 feet) into the air. At times, the geyser stays quiet for years then abruptly bursts back to life– a behavior that has been puzzling scientists. A new…
Drones can help in monitoring explosive volcanoes and prove necessary in a crisis situation, researchers from the GFX German Research Center said. The team presented results of a series of repeated flights with visual and thermal imaging cameras at the Santa Maria…
New research reveals that Hawaii's Pūhāhonu volcano is the largest and hottest shield volcano on Earth, although it is barely visible as only a portion of its tip is exposed above the seafloor. Pūhāhonu, a Hawaiian word which means "turtle surfacing for…
Researchers presented underwater volcanism as a new interpretation of why the sky mysteriously went dark for over a year beginning 536 A.D., with some parts of Europe and Asia seeing the Sun for only about four hours a day and accounts saying the Sun gave no more…
