|
Two plates slide or glide past each other.

Detailed explanation-1: -The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.
Detailed explanation-2: -Plates can move past each other in the same plane at a boundary. This type of boundary is called a transform boundary. This type of boundary is dominated by strike-slip faulting, although other types of faulting may be observed. Where two plates slide past each other, earthquakes originate at shallow depths.
Detailed explanation-3: -Tectonic Plate Boundaries The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.
Detailed explanation-4: -At transform boundaries, two plates slide past each other horizontally. This motion creates energy that is released in the form of earthquakes.
