Geology

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.

Estimates of the size of North Korea's test in September 2017 place it between 70 and 280 kilotons of TNT equivalent.

The volcano famously experienced the largest caldera-forming eruption Europe has seen in the past 200,000 years.

The largest of the quakes measured 4.5 on the Richter scale.

Construction failures are thought to have caused the pit, which measures about 100 ft wide and 50 ft deep.

"You can clearly see the texture of the skin and scales, as well as four-toed claw marks, which are extremely rare," one scientist said.

The gem is roughly the size of a chicken egg.
