Alaska's Augustine Volcano By Ned Rozell Alaska's Augustine Volcano sits alone, a 4,000-foot pyramid on its own island in Cook Inlet. Like many volcanoes, it has a tendency to become top heavy. When gravity acts on Augustine's oversteepened dome, rockslides spill into the ocean. A scientist recently found new evidence for an Augustine-generated tsunami from [...]

Tidal stresses and giant earthquakes

2020-03-07T05:11:21-09:00

Tidal stresses and giant earthquakes By Ned Rozell A scientist once noticed a connection between the stress that tides inflict on the planet and the number of small earthquakes that happen in some areas when that pressure is greatest. She saw a pattern to these earthquakes leading up to great tsunamis. A graduate student is [...]
