Extra-Terrestrial Impacts May Have Triggered 'Bursts' of Plate Tectonics

When -- and how -- Earth's surface evolved from a hot, primordial mush into a rocky planet continually resurfaced by plate tectonics remain some of the biggest unanswered questions in earth ... read more

Living at the Edge of an Active Volcano: Risk from Lava Flows on Mount Etna

On Mt. Etna volcano, inhabited areas have been inundated repeatedly by lava flows in historical times. The increasing exposure of a larger population, which has almost tripled in the area around Mt. ... read more

New Technology Developed to Improve Forecasting of Earthquakes, Tsunamis

Geoscientists have successfully developed and tested a new high-tech shallow water buoy that can detect the small movements and changes in the Earth's seafloor that are often a precursor to ... read more

First Evidence of Bio-Essential Sugars in Meteorites

A new study has discovered meteorites containing RNA sugar, ribose, and other bio-important sugars; the first direct evidence of bio-essential sugars' delivery from space to the ... read more

Underwater Robotic Gliders Provide Key Tool to Measure Ocean Sound Levels

At a time when ocean noise is receiving increased global attention, researchers have developed an effective method to use an underwater robotic glider to measure sound levels over broad areas of the ... read more

Rare Gas Find Solves Puzzle of Southern Africa's Soaring Landscape

The discovery of gases released from deep beneath the Earth's crust could help to explain Southern Africa's unusual landscape, a study ... read more

Secret of Explosive Volcanism Unlocked

When will the next eruption take place? Examination of samples from Indonesia's Mount Merapi show that the explosivity of stratovolcanoes rises when mineral-rich gases seal the pores and ... read more

Global Climate Change Concerns for Africa's Lake Victoria

Researchers have developed a model to project lake levels in world's largest tropical ... read more

Fault-Slip: AI to Simulate Tectonic Plate Deformation

Scientists have transformed the UNICORN computing code into an AI-like algorithm to more quickly simulate tectonic plate deformation due to a phenomenon called a ''fault slip,'' a ... read more

Individual Climate Models May Not Provide the Complete Picture

Equilibrium climate sensitivity -- how sensitive the Earth's climate is to changes in atmospheric carbon dioxide -- may be underestimated in individual climate models, according to a team of ... read more

Ancient Rain Gauge: New Evidence Links Groundwater, Climate Changes in Deep Time

Changes in groundwater millions of years ago created alternating layers of vivid yellow and brown in the mineral sphalerite, and those variations align with movements in Earth's orbit that ... read more

This Is What the Monsoon Might Look Like in a Warmer World

In the last interglacial period on Earth about 125,000 years ago, the Indian monsoon was longer, more extreme and less reliable than it is today. This is the conclusion drawn after analyses of a ... read more

Shedding New Light on Earthquake That Killed 9,000 People

For decades, scientists have debated the structure of the Main Himalayan Thrust -- the fault responsible for a 2015 earthquake that killed nearly 9,000 people, injured 22,000, and destroyed 600,000 ... read more

Scientists Find Eternal Nile to Be More Ancient Than Previously Thought

The Nile's unchanging path has been a geologic mystery because long-lived rivers usually move over time. Researchers have cracked the case by linking the river's flow to the movement of ... read more

Geoscientists Hope to Make Induced Earthquakes Predictable

Geoscientists have created a model to forecast induced earthquake activity from the disposal of wastewater after oil and gas ... read more

Deep Sea Vents Had Ideal Conditions for Origin of Life

By creating protocells in hot, alkaline seawater, a research team has added to evidence that the origin of life could have been in deep-sea hydrothermal vents rather than shallow ... read more

Climate Models and Geology Reveal New Insights Into the East Asian Monsoon

A team of scientists have used climate models and geological records to better understand changes in the East Asian monsoon over long geologic time ... read more

What Makes Earth's Surface Move? Could the Surface Drive Mantle Movement?

Do tectonic plates move because of motion in the Earth's mantle, or is the mantle driven by the plates' movement? Or could it be that this question is ill-posed? This is the point of view ... read more

Southern California Earthquakes Increased Stress on Major Fault Line

A new study has found that last summer's Ridgecrest earthquakes in Southern California earthquakes increased stress on the Garlock Fault, which has been dormant for at least a ... read more
