A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.

Seismic tremors reveal a shallow fragment of ancient tectonic plate beneath Northern California, helping explain damaging ...

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 ...

A switch from a humid to a dry climate has led the Eastern African Rift Zone to pull apart more freely, new research finds.

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San ...

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 ...

Ground fissures and tectonic faults represent critical structural features within sedimentary basins, where the interplay of regional stress fields, depositional environments and, at times, human ...

Earthquakes have long been associated with fault lines, jagged edges where tectonic plates meet and collide. Several studies explain how these seismic activities are not limited to these boundaries.

Researchers have identified an ancient tectonic fragment, the Pioneer fragment, buried under the coast, which may exacerbate earthquake hazards associated with the San Andreas and Cascadia faults.

Take yourself back to fifth-grade science for a second. You might have learned that earthquakes are caused by the sudden movement of big, underground sheets of rock, called tectonic plates. Your ...
