The magnitude-4.0 earthquake that rattled people awake across the Puget Sound region last Wednesday probably struck on the western edge of the Seattle Fault, according to geologists.
Even in port, it's easy to see how the research vessel Chikyu got its nickname. From the waterline to the top of its drilling derrick, the vessel also known as "Godzilla-Maru" towers nearly 30 stories tall.
When a segment of a major fault line goes quiet, it can mean one of two things: The "seismic gap" may simply be inactive—the result of two tectonic plates placidly gliding past each other—or the segment may be a source ...
Using high-resolution topography models not available in the past, geologists can greatly enrich their research. However, current methods of acquisition are costly and require trained personnel with high-tech, cumbersome ...
A senior federal nuclear expert is urging regulators to shut down California's last operating nuclear plant until they can determine whether the facility's twin reactors can withstand powerful shaking from nearby earthquake ...
(Phys.org) —Victoria University of Wellington researchers have discovered that seismic waves produced by earthquakes happening several hundred kilometres away trigger activity deep beneath the Alpine Fault.
To understand earthquakes, scientists have hatched an audacious plan - go straight to the source.
A strong, shallow earthquake shook the seas off eastern Indonesia on Wednesday, but did not cause major damage.
For the first time, a New Zealand-led international science team will gather data by drilling a 1.3-kilometre hole in the Alpine Fault in the South Island.
As scientists learn more about earthquakes that rupture at fault zones near the planet's surface—and the mechanisms that trigger them—an even more intriguing earthquake mystery lies deeper in the planet.
