Since 2011, scientists have been puzzled about the force resulting from a gigantic earthquake and tsunami that destroyed, among other things, Japan's Fukushima Nuclear Plant. Now, a Guinness World ...

When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. West Coast could shake violently for five minutes, and tsunami waves as tall as 100 feet could barrel toward shore.

Scientists warn that the plate beneath Gibraltar arc will begin to shift toward the Atlantic within 20 million years.
