A tsunami struck a fjord in East Greenland in 2023, ringing seismometers for nine straight days. A new satellite study ...

"The United Nations declaration of June 30 as Asteroid Day is a very important milestone for us," Asteroid Day co-founder ...

A full-polarimetric borehole radar system is presented with combinations of dipole antennas and axial slot antennas and is applied to subsurface fracture measurement. First, to determine a scattering ...

Existing warning systems are often based on sea-level sensors like DART buoys that only detect tsunamis after they arrive, leaving little time to respond. By the time the signal is clear to warning ...

In the afternoon heat, scientists check one of the 10 strong motion sensors around the Virgin Islands. The devices are part of a network of 66 sensors managed by the Puerto Rico Strong Motion Program ...

On July 23, 2024, steam exploded from the ground beneath Black Diamond Pool in the area, destroying a park boardwalk and launching water, mud, rocks, and other debris up to 600 feet into the air ...

Ms. Caputo varies the length of her poles on every hike. “On the way down, I like them a little longer to help with bigger drop-offs,” she said. “On the way up, if I need to use my hands to ...

Visualise a heartbeat deep down under the Earth; soft, periodic, and undetectable to the human eye. Every 26 seconds, a faint seismic pulse emanates from deep within the Earth's crust. It does not ...

The corridor contains eight seismometers, but with the interrogator in place, each 10-meter segment of fiber optic cable captured seismic waves – the equivalent of 8,000 seismometers, Ichinose said.

The device captured a variety of small earthquakes as well as the magnitude 3.9 earthquake that rattled the Tri-Valley on March 17. Compared to traditional seismometers, which consist of ...

The sediments underlying the Salt Lake Valley are thicker in places than previously thought, indicating that current seismic hazard models likely underestimate the amount of shaking Utah's ...

This faint tremor, too subtle for humans to feel, has baffled scientists for decades. Earth pulses rhythmically every 26 seconds, detected by seismometers. The phenomenon, known as a microseism ...
