Dark Fiber: Using Sensors Beneath Our Feet to Tell Us About Earthquakes, Water, and Other Geophysical Phenomena

Berkeley Lab researchers successfully use distributed acoustic sensing for seismic monitoring Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown for the first time that dark fiber – the vast network of unused fiber-optic cables … Continue reading

Hacking a pressure sensor to track gradual motion along marine faults

Deep below the ocean’s surface, shielded from satellite signals, the gradual movement of the seafloor — including along faults that can unleash deadly earthquakes and tsunamis — goes largely undetected. As a result, we know distressingly little about motion along … Continue reading

Earthquakes, ‘Marsquakes,’ and the possibility of life

A new study shows that rocks formed by the grinding together of other rocks during earthquakes are rich in trapped hydrogen — a finding that suggests similar seismic activity on Mars may produce enough hydrogen to support life.

Oso disaster had its roots in earlier landslides

The disastrous March 22 landslide that killed 43 people in the rural Washington state community of Oso involved the “remobilization” of a 2006 landslide on the same hillside, a new federally sponsored geological study concludes. The research indicates the landslide, … Continue reading

New study reveals insights on plate tectonics, the forces behind earthquakes, volcanoes

The Earth’s outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought to understand the plates’ fundamental properties and the mechanisms that … Continue reading

NASA’s Kepler Mission Discovers Tiny Planet System

PASADENA, Calif. — NASA’s Kepler mission scientists have discovered a new planetary system that is home to the smallest planet yet found around a star similar to our sun. The planets are located in a system called Kepler-37, about 210 … Continue reading
