Plate tectonics not needed to sustain life

There may be more habitable planets in the universe than we previously thought, according to Penn State geoscientists, who suggest that plate tectonics—long assumed to be a requirement for suitable conditions for life—are ...

Indonesia's 'child' of Krakatoa spews ash and lava

An Indonesian volcano known as the "child" of the legendary Krakatoa erupted on Thursday, spewing a plume of ash high into the sky as molten lava streamed down from its summit.

Using fibre-optic cables to detect earthquakes

Fibre-optic cables can be used to detect earthquakes and other ground movements. The data cables can also pick up seismic signals from hammer shots, passing cars or wave movements in the ocean. This is the result of a study ...

Flow in the asthenosphere drags tectonic plates along

New simulations of Earth's asthenosphere find that convective cycling and pressure-driven flow can sometimes cause the planet's most fluid layer of mantle to move even faster than the tectonic plates that ride atop it.

East vs. West Coast earthquakes

Why was an earthquake in Virginia felt at more than twice the distance than a similar-sized earthquake in California? The answer is one that many people may not realize. Earthquakes east of the Rocky Mountains can cause noticeable ...
