California's supervolcano is showing increased seismic activity - more than 2,000 quakes hit in recent years. Scientists conducted an investigation to see if it is a sign of impending doom.
A dormant supervolcano has had increased seismic activity over the years. Experts identified more than 2,000 quakes throughout the Long Valley Caldera. READ MORE:California's supervolcano that has the power to bury Los Angeles in more than 3,000 feet of ash is showing signs of activity.
Caltech researchers created detailed underground images of the caldera, finding that the recent seismic activity results from fluids and gases released as the area cools off and settles down. The long-dormant volcano was the site of a super explosion 767,000 years ago, releasing 140 miles of volcanic material into the atmosphere and devastating the land.

The moon is 40 million years OLDER than scientists thought, study claimsSince the 1970s, astronomers have suspected that the moon was created when a giant protoplanet called Theia struck Earth. In a new study, researchers from Durham University claim that the impact immediately placed the moon into orbit around Earth.
