A new global geologic map of Mars is the most thorough representation of the "Red Planet's" surface, bringing together observations and scientific findings from four orbiting spacecraft that have…

The Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland— 1,500 miles - except for a curious bend in Pennsylvania and New York. Why it bends has been a mystery.…

Volcanic hazards aren't limited to eruptions, debris landslides can also cause a great deal of damage and loss of life.  Stratovolcanoes, with their steep, conical shapes made up of lava and…

The moon's surface has by millions of craters but it also has over 200 holes – and those steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for…

By measuring how fast Earth conducts electricity and seismic waves, researchers have created a detailed picture of Mount Rainier's deep volcanic plumbing and partly molten rock that will erupt again…

Rainwater can penetrate below the Earth's fractured upper crust, according to a new study. It had been thought that surface water could not penetrate the ductile crust, where temperatures of more…

It's not a secret that groundwater levels in Texas have declined since the Dust Bowl era - the obvious reasons are what you expect - more population and more food grown to sustain them. But there are…

What is the impact of volcanic sulfate emissions on climate? Researchers have completed the most accurate and precise reconstruction to date of historic volcanic sulfate emissions in the Southern…

The earthquakes in central Oklahoma since 2009 are likely attributable to subsurface wastewater injection at a handful of disposal wells - Oklahoma earthquakes constitute nearly half of all central…

Tsunami earthquakes are rare but they happen at relatively shallow depths in the ocean. So while are small in terms of their magnitude, they create very large tsunamis, with some earthquakes that…
