The first survey of methane vent sites off Washington's coast finds 1,778 bubble columns, with most located along a north-south band that is in line with a geologic ... read more

Storm Waves Can Move Boulders We Thought Only Tsunamis Had the Power to Shift

It's not just tsunamis that can change the landscape: storms shifted giant boulders four times the size of a house on the coast of Ireland in the ... read more

New Early Gravity Signals to Quantify the Magnitude of Strong Earthquakes

After an earthquake, there is a disturbance in the field of gravity almost instantaneously. This could be recorded before the seismic waves. Researchers have managed to observe these weak signals and ... read more
