The flanks of many island volcanoes slide very slowly towards the sea. Whether these landslides are forewarnings of a catastrophic collapse or, on the contrary, even reduce its risk, is not yet understood. Geophysicists now show that sporadic, slow landslides on the small volcanic island of Ritter Island in New Guinea preceded a catastrophic collapse.
Scientists have employed a new method utilizing tsunami signals to calculate the calving magnitude of an ocean-terminating glacier in northwestern Greenland, uncovering correlations between calving flux and environmental factors such as air temperature, ice speed, and ocean tides.
The central Salish Sea of the Pacific Northwest is bounded by two active fault zones that could trigger rockfalls and slumps of sediment that might lead to tsunamis.
A study of solitary tsunami-style wave clusters shows how they move in harmony with and through each other.
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 fault.
The Kaikoura earthquake in New Zealand in 2016 caused widespread damage. Researchers have now dissected its mechanisms revealing surprising insights on earthquake physics with the aid of simulations carried out on a supercomputer.
Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell the difference between life and death. Researchers demonstrate a new earthquake detection method -- their technique exploits subtle telltale gravitational signals traveling ahead of the tremors. Future research could boost early warning systems.
Earthquakes happen when rocks on either side of a tectonic fault shift suddenly in opposite directions. Two main seismic waves that carry shaking out of a breaking fault are "S" waves, which shear rocks and propagate at about 3.5 km/s, and "P" waves, which compress rocks and propagate faster at about 5 km/s.
