New tectonic fault identified 200 kilometers southwest of Portugal may explain historic Lisbon earthquakes and pose future tsunami risks.

A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of the time, making the technique the most accurate so far.

One of the worst earthquakes in European history ripped through Portugal in 1755, causing a tsunami, fires and shaking that ...
