Giant 'balloon of magma' inflates under Santorini

A new survey suggests that the chamber of molten rock beneath Santorini's volcano expanded 10-20 million cubic metres – up to 15 times the size of London's Olympic Stadium – between January 2011 and April 2012.

Hawaiian hot spot has deep roots

(PhysOrg.com) -- Hawaii may be paradise for vacationers, but for geologists it has long been a puzzle. Plate tectonic theory readily explains the existence of volcanoes at boundaries where plates split apart or collide, but ...

A new type of seismic sensor to detect moonquakes

During the Apollo missions of the 1970s, several seismometers were flown to the moon, where they collected data on lunar seismic trembling for eight years. The data showed some lunar quakes were as powerful as a magnitude ...

Fiber optic cables detect and characterize earthquakes

In California, thousands of miles of fiber optic cables crisscross the state, providing people with internet. But these underground cables can also have a surprising secondary function: they can sense and measure earthquakes. ...

Enhancing earthquake detection from orbit

When a major earthquake strikes, nearby seismometers can inform rapid alerts to residents and emergency services that potentially hazardous shaking or tsunamis may be headed their way. However, local seismometer measurements ...

Citizen seismology helps decipher the 2021 Haiti earthquake

On August 14, 2021, a magnitude 7.2 earthquake struck Haiti, leaving 2,500 dead, 13,000 injured and roughly 140,000 houses destroyed. This came 11-years after Haiti was struck by a 7.0 earthquake that devastated the capital ...

NASA balloon detects California earthquake—next stop, Venus?

Between July 4 and July 6, 2019, a sequence of powerful earthquakes rumbled near Ridgecrest, California, triggering more than 10,000 aftershocks over a six-week period. Seeing an opportunity, researchers from NASA's Jet Propulsion ...

Icy ocean worlds seismometer passes further testing in Greenland

The NASA-funded Seismometer to Investigate Ice and Ocean Structure (SIIOS) performed well in seismic experiments conducted in snowy summer Greenland, according to a new study by the SIIOS team led by the University of Arizona ...
