Undersea earthquakes and volcanic eruptions displace destructive amounts of water and send it across oceans to flood distant ...

Earthquakes occurring away from tectonic plate boundaries can be triggered by the rise and fall of hot material through the Earth's mantle, according to a new study.

The Resurrection tectonic plate has been a debate among the scientific community for years, but new data suggests the long lost plate sits more than 250 miles beneath a region in northern Canada.

The biggest changes to the plate model have been in western North America, which often has the boundary with the Pacific Plate drawn as the San Andreas and Queen Charlotte Faults.

"Volcanoes form at plate boundaries, and the more plates you have, the more volcanoes you have," Jonny Wu, a geologist at the University of Houston, said in a statement. "Volcanoes also affect ...
