Geologists Are Using Artificial Intelligence to Predict Landslides

Many factors influence where a landslide will occur, including the shape of the terrain, its slope and drainage areas, the material properties of soil and bedrock, and environmental conditions like climate, rainfall, hydrology and ground motion resulting from earthquakes. Geologists have developed ...

Research Reveals Sources of CO2 from Aleutian-Alaska Arc Volcanoes

Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than ...

Climate Change Will Increase Impacts of Volcanic Eruptions

Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But a volcanologist said these fundamental questions remain a ...

Multiscale Rupture Growth Driven by a Complex Fault Network During the 2023 Türkiye and Syria Earthquake Doublet

Researchers analyzed the source processes of the twin earthquakes that caused extensive damage in Türkiye and Syria on February 6, 2023. The results revealed that a complex fault network with bends, steps, and branches controlled the propagation ...

Extinct Offshore Volcano Could Store Gigatons of Carbon Dioxide

一个new study concludes that an extinct volcano off the shore of Portugal could store as much as 1.2-8.6 gigatons of carbon dioxide, the equivalent of ~24-125 years of the country's industrial ...

Eruption of Tonga Underwater Volcano Found to Disrupt Satellite Signals Halfway Around the World

研究人员发现,Hunga-Tonga喷发佤邦s associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based ...

Wildfire Spread Risk Increases Where Trees, Shrubs Replace Grasses

一个new study found that as woody plants like shrubs and trees replace herbaceous plants like grasses, spot fires can occur farther away from the original fire ...

Past Climate Change to Blame for Antarctica's Giant Underwater Landslides

Scientists found weak, biologically-rich layers of sediments hundreds of meters beneath the seafloor which crumbled as oceans warmed and ice sheets declined. The landslides were discovered in the ...

Impact of Ancient Earthquake Revealed

By combining the scientific powerhouses of genetics and geology, researchers have identified a new area of coastal uplift, which had been hiding in plain ...

Creating a Tsunami Early Warning System Using Artificial Intelligence

Researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater ...

Ridgecrest Faults Increasingly Sensitive to Solid Earth Tides Before Earthquakes

Faults in the Ridgecrest, California area were very sensitive to solid earth tidal stresses in the year and a half before the July 2019 Ridgecrest earthquake ...

Puerto Rico Tsunami Deposit Could Have Come from Pre-Columbian Megathrust Earthquake

Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according ...

Turkey's Next Quake: Research Shows Where, How Bad -- But Not 'When'

Using remote sensing, geophysicists have documented the massive Feb. 6 quake that killed more than 50,000 people in Eastern Turkey and toppled more than 100,000 buildings. Alarmingly, researchers ...

New USGS-FEMA Report Updates Economic Risk from Earthquakes

Even though most of the economic losses are concentrated in California and along the West Coast due to that region's high seismic hazard levels, significant population, and building exposure, ...

Plate Tectonic Processes in the Pacific and Atlantic During the Cretaceous Period Have Shaped the Caribbean Region to This Day

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...


Biological Invasions as Costly as Natural Disasters

Over the past 40 years, the financial losses caused by biological invasions have been equivalent to those caused by various types of natural disasters, such as earthquakes, floods or storms; however, ...

2022 Tongan Volcanic Explosion Was Largest Natural Explosion in Over a Century, New Study Finds

The 2022 eruption of a submarine volcano in Tonga was more powerful than the largest U.S. nuclear explosion, according to a new study. The 15-megaton volcanic explosion from Hunga Tonga-Hunga ...

Wildfires and Animal Biodiversity

Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative ...

Predictive Power of Climate Models May Be Masked by Volcanoes

Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new ...

Study Re-Evaluates Hazards and Climate Impacts of Massive Underwater Volcanic Eruptions

Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new ...

The 2022 Durban Floods Were the Most Catastrophic Yet Recorded in KwaZulu-Natal

Research shows flooding events in the province have doubled in the last ...

Warm Liquid Spewing from Oregon Seafloor Comes from Cascadia Fault, Could Offer Clues to Earthquake Hazards

Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' ...

The Unexpected Contribution of Medieval Monks to Volcanology

By observing the night sky, medieval monks unwittingly recorded some of history's largest volcanic eruptions. An international team of researchers drew on readings of 12th and 13th century ...

Preventing Urban Flooding in the Face of Climate Change

Planners have come up with many innovative ways to prevent flooding caused by heavy downpours -- from planting rain gardens to installing green roofs. But in many cases, nothing works quite as well ...
