Are subterranean lifeforms viable on Mars? A new interpretation of Martian seismic data by scientists Ikuo Katayama of ...

A spacecraft's sample return capsule was detected entering the Earth's atmosphere using acoustic sensors by a team of ...

The company suspended fracturing activity after the quake and is not planning a restart at that well pad, the regulator said.

The region the researchers examined is covered by a network of borehole seismometer stations placed about every 25 kilometers. Because the seismometers are placed about 100 meters deep in boreholes, ...

Earthquakes occur along fault lines between continental plates, where one plate is diving beneath another. Pressure builds between each plate, called fault stress. When this stress builds enough to ...
