Following the quake, tsunami warnings were issued but these were subsequently retracted.

Scientists have mapped a large body of freshwater that could offer New Zealand a new supply of water.

"Finding these 'lost' pieces is like finding a missing piece of a puzzle. The scientific puzzle of the ancient Earth can't be complete without all of the pieces," said researcher Maya Kopylova.

The Yellow River—the second longest in the country—is sometimes referred to as "China's sorrow" due to its tendency over the centuries to produce devastating floods.

Clues in ancient rock suggest the early Earth did not have continents like we have today, but was covered by an ocean.

"We've been planning this mission and executing for the last 10 years—and the initial results are really exciting," Bruce Banerdt, InSight principal investigator said.

The volcano—located around 85 miles south of Ecuador's capital in the Andes mountains—has been frequently active since 1999.

The small earthquakes were recorded by the USGS near Greenback and Sweetwater.

"The ocean floor is just as variable and interesting in its geology as the continents," planetary scientist James O'Donoghue said.

Scientists watch rare event unfold after unusual seismic activity was recorded in the Indian Ocean.

The scientists say the latest findings could have implications for our understanding of several geological processes .

The quake is the latest in a series of tremors that have struck the region in recent months.

It is unclear how the holes were formed, although marine trash could partly be responsible.

"The Garlock Fault has been quiet for a long time. But there's geologic evidence that there have been large earthquakes on it," the lead author of a new study said.

Scientists have uncovered a geological explanation for why some volcanic eruptions are more explosive than others.

The geode contains crystals over six foot tall, which are so clear they look like ice.

The desert's age has been the topic of debate for decades among scientists.

The photo was taken by the ExoMars Trace Gas Orbiter—a spacecraft developed by the European Space Agency and the Russian space agency Roscosmos.

The land mass, now called Greater Adria, split from supercontinent Gondwana 240 million years ago during the Triassic Period—but was forced into the Earth's mantle 140 million years later, when it came into contact with what is now Southern Europe.

For the study, scientists recreated the extreme pressure and temperature of the moon's interior in the laboratory.

The 'abiotic' methane may hold clues about its presence elsewhere in the solar system, researchers say.

Warmer conditions on Ancient Mars increase the possibility that life developed there, according to researchers.

The magnetic field last flipped 795,000 years ago in an event called the Matuyama-Brunhes reversal.

When exactly plate tectonics emerged and how it has evolved through time are two of the most significant and hotly debated questions in Earth sciences today.

Earth is not the only place that experiences quakes.

Discovery could help our understanding of how and when the magnetic field was turned on.

Steamboat is the world's tallest currently active geyser, capable of shooting jets of boiling hot water more than 300 feet into the air.

The volcano—located in the North Pacific—has long been dormant, with its last eruption occurring in 1924.

The aquifer stretches from Massachusetts to New Jersey—the biggest formation of its kind ever found.

Helium is a vital element in several industries, and a global shortage could have devastating effects.
