Currently, much of the thinking around risks posed by volcanoes follows a simple equation: the bigger the likely eruption, the worse it will be for society and human welfare.
Traces of the gas phosphine point to volcanic activity on Venus, according to new research from Cornell University.
A massive volcanic eruption in Indonesia about 74,000 years ago likely caused severe climate disruption in many areas of the globe, but early human populations were sheltered from the worst effects, according to a Rutgers-led study.
The history of pyroclastic surges is written in the landscapes they ravage. Volcanic dunes and other deposits hold debris from ancient eruptions, as do craters marking sites of ancient blasts. This study focuses on Ubehebe and El Elegante.
Data collected by University of Rhode Island Professor Stéphan Grilli and his colleagues will appear in Nature Communications, which is considered one of the world’s leading multidisciplinary science journals.
An international team of scientists has analyzed chemicals in an ice core from West Antarctica to compile the most accurate chronology of volcanic eruptions during the last 11,000 years produced thus far.
Volcanic eruptions deep in our oceans are capable of extremely powerful releases of energy, at a rate high enough to power the whole of the United States, according to research published today.
What would a volcano – and its lava flows – look like on a planetary body made primarily of metal? A pilot study offers insights into ferrovolcanism that could help scientists interpret landscape features on other worlds.
The Volcano Alert Level (VAL) system, standardized by the United States Geological Survey (USGS) in 2006, is meant to save lives and keep citizens living in the shadow of an active volcano informed of their current level of risk. A new study published in Risk Analysis suggests that, when an alert remains elevated at any level above “normal” due to a period of volcanic unrest, it can cause a decline in the region’s housing prices and other economic indicators. Because of this, the authors argue that federal policymakers may need to account for the effects of prolonged volcanic unrest — not just destructive eruptions — in the provision of disaster relief funding.
In a new study, a team of paleoclimate researchers used a proxy product that employs natural climate archives to better understand the global and seasonal hydroclimate impacts of all known large tropical eruptions over the last millennium.
The study gives the first detailed description of a volcanic eruption from Sierra Negra found on Isla Isabela - the largest of the Galápagos Islands and home to nearly 2,000 people.
Earthquakes in the Black Rock Desert are rare and capturing the seismic recordings from these earthquakes provides a glimpse into the volcanic system of the Black Rock Desert that, while not showing any signs of erupting, is still active.
Volcanologists from the University of Georgia and two Swiss universities found a link between carbon dioxide and the volume of gas trapped in magma, which could help predict the intensity and magnitude of a volcanic eruption.
In 1991, a a volcanic peak on the Philippine Island of Luzon had the second-most powerful volcanic eruption of the 20th century. Eight hundred people lost their lives, and lush ecosystems were destroyed. In recent years, scientists surveyed the surviving mammal populations, and rediscovered a species of mouse that had long been feared to be extinct.
There isn't much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka's Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years.
Microscopic bubbles can tell stories about Earth's biggest volcanic eruptions and geoscientists from Rice University and the University of Texas at Austin have discovered some of those stories are written in nanoparticles.
ORNL story tips: Volcanic microbes, unbreakable bonds and flood mapping
Around 1085 AD, along the southern rim of Northern Arizona's elevated Colorado Plateau, a volcano erupted, forever changing ancient Puebloan fortunes and all nearby life.
A small group of volcanic islands in Alaska's Aleutian chain might be part of a single, undiscovered giant volcano, say scientists presenting the findings Monday, 7 December at AGU's Fall Meeting 2020.
