GEOLOGY

Detailed explanation-1: -These intraplate earthquakes are caused by stresses within a plate. Since plates move over a spherical surface, zones of weakness are created. Intraplate earthquakes happen along these zones of weakness. The earthquakes may take place along ancient faults or rift zones.

Detailed explanation-2: -The 2001 Gujarat earthquake was caused by movement on a previously unknown south-dipping fault, trending parallel to the inferred rift structures. No major surface ruptures were associated with the shock, classifying it as a blind thrust earthquake.

Detailed explanation-3: -The term intraplate earthquake refers to a variety of earthquake that occurs within the interior of a tectonic plate; this stands in contrast to an interplate earthquake, which occurs at the boundary of a tectonic plate.

Detailed explanation-4: -Earthquakes Can Happen Along Intraplate Faults Earthquakes can occur along faults far from the edges of plates. Although these earthquakes are much less common, they are due to the same forces that cause earthquakes along plate boundaries.
