A seamount sitting on a subducting tectonic plate off the coast of Japan and plowing its way into Earth's mantle may be at the root of several magnitude 7 earthquakes in the past 40 years. When you ...

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise ...

NORFOLK, Va. — Fault lines are fractures or breaks in the Earth's crust where tectonic plates move past each other, often resulting in earthquakes. These geological features are classified into three ...

Picture this: a massive horseshoe of fire wrapping around an entire ocean, where the ground shakes almost daily and volcanoes erupt with terrifying regularity. The Ring of Fire spans approximately 40, ...

The 4.8-magnitude earthquake on the East Coast Friday came from ancient dormant faults. The faults formed when two continents collided about 500 million years ago, creating the Appalachians and ...

Two of the biggest fault lines in the world are synched together in a way that could lead to disastrous consequences, according to recent scientific analysis. This synchronization raises alarms about ...

Earthquakes don’t occur everywhere. They occur along the boundaries of the earth’s tectonic plates, along either known active faults or dormant faults. The East Coast is crisscrossed with ancient ...

Over here in the Midwest, we're much more familiar with tornadoes, floods, freezes and other severe weather incidents. Earthquakes remain an afterthought — but they're not impossible. According to the ...
