Phobos surface striations tell a story of its rupturing interior

Phobos, the 22-km diameter innermost moon of Mars, is a groovy body. Unlike its little brother Deimos, Phobos has developed a striking pattern of parallel linear features running across its surface. These grooves are a distinctive ...

Faint foreshocks foretell California quakes

New research mining data from a catalog of more than 1.8 million southern California earthquakes found that nearly three-fourths of the time, foreshocks signalled a quake's readiness to strike from days to weeks before the ...

Artificial intelligence improves seismic analyses

The challenge to analyze earthquake signals with optimum precision grows along with the amount of available seismic data. At the Karlsruhe Institute of Technology (KIT), researchers have deployed a neural network to determine ...

Measuring iceberg production with earthquakes

Global warming is significantly reducing the volume of ice sheets—like the one covering Greenland—through melting or by shearing away blocks of ice that tumble into the ocean and become icebergs, a process known as calving.

Scientific computing in the cloud gets down to Earth

In a groundbreaking effort, seismology researchers have conducted a continent-scale survey for seismic signatures of industrial activity in the Amazon Web Services commercial cloud (AWS), then rapidly downloaded the results ...

Fast, simple new assessment of earthquake hazard

Geophysicists at Caltech have created a new method for determining earthquake hazards by measuring how fast energy is building up on faults in a specific region, and then comparing that to how much is being released through ...
