Geologists have uncovered the remains of a massive tectonic plate beneath the Pacific Ocean, a plate that had been hidden for over 160 million years. Known as Pontus, this tectonic giant once covered ...

Invisible earthquakes are revealing a hidden tectonic puzzle beneath California’s most dangerous fault zone.

Scientists have identified a long-lost tectonic plate in the west Pacific Ocean. Called Pontus, the 'mega-plate' was once 15 million square miles, about a quarter the size of the Pacific Ocean today.

In deep Earth, rocks take up and release water all the time, and the effects can be wide reaching. Dehydration can cause rocks to crack and trigger earthquakes, and over geologic timescales, this ...
