boomerang earthquake

Scientists spot rare ‘boomerang earthquake’ in the ocean

August 11th, 2020

Scientists have recorded the first evidence of a so-called “boomerang earthquake” occurring deep in the Atlantic Ocean. A boomerang occurs when a fracture proceeds in one direction before rapidly changing course and traveling back in the opposite direction at even higher speeds. The researchers hope that these observations can help better prepare early warning systems …

Scientists try to explain the weird asymmetry of the Moon

June 24th, 2020

Researchers are searching for an explanation for why the side of the Moon that faces Earth happens to be covered in dark spots, called “maria,” or seas. These areas may be the result of radioactive decay of certain elements found in rocks, generating heat and melting the rocks. The backside of the Moon has almost …

Scientists spot ‘hot, dense structures’ hiding near Earth’s core

June 12th, 2020

Geophysicists have detected large structures hiding near the boundary between Earth’s mantle and core. These structures, which are areas of surprisingly dense rock, were mapped using data gathered from thousands of seismic events such as Earthquakes. The scientists used an AI algorithm to help make sense of the data and reveal the hidden features lurking …

The swirling rocks of Mars are mesmerizing

June 12th, 2020

NASA shows off an area of Mars where the wind has swept away the surface dust and sand to reveal the intricate layers of rock hiding beneath. These rock layers were created by sediment that gradually built up and then hardened over the course of millions of years. Because of Mars’ habit of kicking up …

mud flows on mars

Scientists explain mysterious ‘lava flows’ on Mars

May 18th, 2020

Volcano-like features on Mars may actually be the result of mud flows rather than lava, researchers now say. Using simulated Mars conditions, researchers were able to create mud flows that look a lot like cooled lava flows. Visit BGR’s homepage for more stories. You don’t have to be a space science fan to realize that …

The coronavirus pandemic made the entire Earth quieter

April 2nd, 2020

Coronavirus lockdown measures have forced daily life to change, and that means humans are making less noise on Earth.  With less traffic and other human movements, seismologists are noticing huge dips in the amount of background seismic noise in their readings.  A cleaner reading and less noise could give researchers a rare opportunity to capture …

A day on Earth was a half-hour shorter just 70 million years ago

March 10th, 2020

A day on Earth was just 23.5 hours long, 70 million years ago.  Researchers discovered this by studying the growth rings of ancient mollusk fossils.  The findings could tell us more about or planet and its relationship with the Moon.  Visit BGR’s homepage for more stories. A full day on Earth hasn’t always been 24 …

Watch scientists endure the intense shaking of a Marsquake simulation

July 24th, 2019

Humans have never set foot on Mars, but that’s not stopping scientists from doing their best to understand what it might be like when that day eventually comes. Researchers using data from NASA’s InSight lander are taking that idea to the extreme by testing what a particularly intense Marsquake might feel like using a special …
