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 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.

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 ...

NAPA, Calif. (KGO) -- Bigger and stronger than first thought. Scientists uncover new findings about the fault line that caused the 6.0 earthquake in Napa nearly a decade ago. The earthquake in 2014 ...

Researchers have identified an actively creeping section of the Concord Fault running through local communities in California, potentially increasing the risk of large earthquakes in residential ...

Major faults like the San Andreas strike fear of producing devastating earthquakes. But scientists have found that little-known 'branch' faults, minor faults that stem from larger ones, could release ...
