NASA radar demonstrates ability to foresee sinkholes
(Phys.org) —New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and forced evacuations near Bayou Corne, La., that year.
Decline of Bronze Age 'megacities' linked to climate change
Scientists from the University of Cambridge have demonstrated that an abrupt weakening of the summer monsoon affected northwest India 4,100 years ago. The resulting drought coincided with the beginning of the decline of the ...
Research shows temperature, not snowfall, driving tropical glacier size
Temperature, not snowfall, has been driving the fluctuating size of Peru's Quelccaya Ice Cap, whose dramatic shrinkage in recent decades has made it a symbol for global climate change, a Dartmouth-led study ...
Study finds existence of large, deep magma chamber below Kilauea volcano
A new study led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science uncovered a previously unknown magma chamber deep below the most active volcano in the world ...
Charting the slopes of sediment transport
In the Earth Surface Dynamics Lab at the California Institute of Technology (Caltech) the behavior of rivers is modeled through the use of artificial rivers—flumes—through which water can be pumped at ...
Is there an ocean beneath our feet?
(Phys.org) —Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth's oceans to the upper mantle than previously thought.
Volcanic lightning recreated in the lab
An LMU team has, for the first time, created volcanic lightning in the lab and captured it on film. The new findings may permit rapid characterization of ash clouds released by volcanic eruptions and improve ...
Atlas Mountains in Morocco are buoyed up by superhot rock, study finds
The Atlas Mountains defy the standard model for mountain structure in which high topography must have deep roots for support, according to a new study from Earth scientists at USC.
Scientists show how deadly volcanic phenomenon moves
For the first time scientists have tracked how one of the deadliest volcanic hazards moves over time.
Oceanic 'dead zones' and Jurassic extinction
Data collected by a scientist now at the University of Liverpool has predicted a dramatic decline in the size of marine animals used as food by humans, due to reduced oxygen levels in the oceans.
Acid raid, ozone depletion contributed to ancient extinction
Rain as acidic as undiluted lemon juice may have played a part in killing off plants and organisms around the world during the most severe mass extinction in Earth's history.
Greenland's shrunken ice sheet: We've been here before
Think Greenland's ice sheet is small today? It was smaller—as small as it has ever been in recent history—from 3-5,000 years ago, according to scientists who studied the ice sheet's history using a new ...
Sudden climate change varies from country to country
Different countries may have recovered faster than others as the last Ice Age ended, new research shows.
Late Cretaceous Period was likely ice-free
For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University ...
