Earthquakes are notoriously hard to predict, and so too are the usually less-severe aftershocks that often follow a major seismic event.
By examining earthquake models from a fresh perspective, Cornell engineers now show that the earthquake fracture energy – once thought to relate to how faults in the Earth’s crust weaken – is related ...
Major environmental events write their own headlines. With loss of life and crippling infrastructure damage, the aftershocks of earthquakes reverberate around the world — not only as seismic waves, bu...
