Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. Earthquakes happen along "fault lines" in the earth’s crust. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be pr

Earthquakes happen at places calledfaults(orfault lines) where the jagged edges of tectonic plates grind against one another. Most earthquake activity happens in the middles of the oceans where tectonic plates are pushing apart on the floor of the sea. Some of the most violent earthquakes happen...

The biggest earthquakes happen at "subduction zones," the points where one tectonic plate slides under another. Big subduction zone earthquakes can release the same amount of energy as tens of thousands of atomic bombs. The famous San Andreas Fault in California is between the North American Plate...

A trio of seismologists affiliated with Ithe Berkeley Seismological Laboratory reports that a part of the San Andreas Fault, at Parkland, is not producing signals that would suggest an earthquake is going to happen any time soon, but they assert there are factors that suggest otherwise. 7.4...
