A devastating wall of water gushed down the Bhotekoshi/Sunkoshi River in Nepal on July 5, 2016. It came from a lake that had been dammed by a glacial moraine, but the dam broke and discharged more than 100,000 tons of water ...
First came the fire, then the rain—and finally, the devastating mud.
Because instruments were finally installed there, scientists can no longer say that East Antarctica is unusually seismically silent.
“The only thing you can expect is to be surprised.”...
No one can predict when or where an earthquake will strike, but in 2011 scientists thought they had evidence that tiny underground tremors called foreshocks could provide important clues. If true, it suggested seismologists ...
Scientists in China have discovered what they claim are the oldest fossilised animal footprints ever found. The parallel tracks were formed in mud up to 551 million years ago in southern China’s Yangtze Gorges.
Earth scientists consistently look for a reliable way to forecast earthquakes. New research from University of Alaska Fairbanks Geophysical Institute professor Carl Tape may help in that endeavor, due to a unique set of circumstances.
As companies and governments attempt to intensify extraction, cultural resistance offers a space for imagining alternative futures.
An international collaboration of scientists, led by the University of Leicester, has investigated Earth's climate over half a billion years ago by combining climate models and chemical analyses of fossil shells about 1mm ...
Concern over the potential imminent eruptions of Earth's supervolcanoes, like Taupo in New Zealand or Yellowstone in the United States, may be quelled by the results of a new study suggesting that geological signs pointin
The climate of early Mars is a subject of debate. A recent study suggests that the early Martian surface may not have been dominated by ice, but instead it may have been modestly warm and prone to rain, with only small patches of ice.
Researchers developed a unified model of the formation mechanism of spherical carbonate concretions, which often contain exceptionally well-preserved fossils. The carbon in the carbonate originates from the organisms preserved inside the concretions, and the surrounding muddy matrix limits diffusion and permeability, and thus causes supersaturation of carbonate at a reaction front. Calcite precipitation occurs several orders of magnitude more rapidly than previously recognized in concretions. This understanding may have practical applications in sealing technology.
Sputtering lava, strong earthquakes and toxic gas jolted the southern part of the Big Island of Hawaii as magma shifted underneath a restless Kilauea volcano.

A tiny clue found in ancient sediment has unlocked big secrets about Greenland's past and future climate.
Researchers have found a new way to estimate how fast magma is recharging beneath the Yellowstone supervolcano. While their findings offer no help in predicting if the volcano will erupt, they can now get a better understanding of a key factor -- a pool of basalt magma recharging the system -- in...
Two papers provide exciting answers to very old questions. Richard A Lovett reports.
The museum opened in 1988 on the site of the former Caphouse Colliery, near Wakefield.
Researchers in the Department of Earth Sciences at Syracuse University have confirmed that rising oceanic and atmospheric oxygen levels co-evolved with marine life hundreds of millions of years ago.
The Pacific region has seen two high-profile eruptions in recent weeks - but be wary of dramatic headlines about possible catastrophe.
Hawaii's Kilauea volcano could soon send boulders and ash shooting out of its summit crater in the kind of explosive eruption last displayed nearly a century ago.
After 25 years of collecting fossils at a Pennsylvania site, scientists at the Academy of Natural Sciences of Drexel University now have a much better picture of an ancient, extinct 12-foot fish and the world in which i
Camouflage and mimicry are pervasive throughout the biological world as part of the usual interactions between predators and their prey, allowing both to avoid detection. Among insects, the icons of mimicry include familiar stick and leaf insects, leaf-like moths and katydids.
For a time, the land around the village of Longa Mali in eastern Cameroon was one of the most prized in Africa, and powerful machines gnawed greedily into its soil to extract precious gold.
Earth looked very different 600 million years ago
We all recognise the names of some time periods such as Jurassic or Devonian - but how many us of actually understand how geologists divide up the earth’s past?
