Variations in Creep Along One of Earth’s Most Active Faults
Satellite-based radar images of motion along Turkey’s North Anatolian Fault are helping scientists understand when, where, and how creep occurs and its implications for seismic hazard.
Afghanistan’s Blob Hunters
How a first-of-its-kind team of Afghan scientists and engineers helped make a monolithic discovery.
The Quaking, Shrinking Moon
New evidence suggests that the Moon may still be tectonically active.
Monitoring Haiti’s Quakes with Raspberry Shake
A network of “personal seismometers” is intended to complement Haiti’s national seismic network to engage and inform residents about earthquake hazards and preparation.
More Than 30,000 Earthquakes Trace the Movement of Magma
Seismometers near Iceland’s Bárðarbunga volcanic system pinpointed thousands of earthquakes in 2014–2015, revealing where molten rock was moving underground before any eruptions occurred.
The Blob Causing Earthquakes
Geophysicists discover that a “blob” of rock sinking into the mantle is the force triggering earthquakes in the Hindu Kush.
First Possible Marsquake Detected
First earthquakes, then moonquakes, now marsquakes: a robotic lander comes through with the first detection of seismic activity on Mars.
All Types of Large Earthquakes Produce Prompt Gravity Signals
New observations of recently discovered gravity perturbations that precede seismic waves have the potential to improve earthquake early-warning systems in California and other tectonic settings.
More Than a Million New Earthquakes Spotted in Archival Data
By reanalyzing seismic records, researchers found a plethora of tiny earthquakes in Southern California that trace new fault structures and reveal how earthquakes are triggered.
