Venezuela’s deadly earthquakes happened on a fault similar to the San Andreas, and the risks aren’t over yet – a geophysicist explains

Both faults are along plate boundaries that move in similar ways and have ruptured in enormously destructive earthquakes in the past.

The Cascadia Subduction zone isn’t shutting down – but it’s more complicated than we thought

The interpretation that the subduction zone is winding down gets ahead of the science. What the new research actually shows is far more complex and interesting.

What causes volcanoes to erupt?

As they shape the Earth, volcanoes inspire and terrify humans.

Seismologists can’t predict an impending earthquake, but longer‑term forecasts and brief warnings after one starts are possible

The idea that scientists could warn a region that a big quake was coming at a certain time – with enough advance notice for large-scale preparation and evacuation – remains a dream, not a reality.
