GEOLOGY

Detailed explanation-1: -They also occur on continents along strike-slip faults like California’s San Andreas, where two plates move horizontally in opposite directions. Occurring close to the surface, in the upper 3-5 kilometers (km) of the fault, this slow, silent movement is referred to as “creep events.”

Detailed explanation-2: -The slow and continuous movement of two sides of an active fault relative to one another can noticed over time; this movement is called fault slip.

Detailed explanation-3: -Seismic creep is the constant or periodic movement on a fault as contrasted with the sudden rupture associated with an earthquake. It is a usually slow deformation of rock resulting from constant stress being applied over a period of time.

Detailed explanation-4: -Fault creep is aseismic fault slip that occurs in the uppermost part of the earth’s crust during the time interval between large stress-releasing earthquakes on a fault or as “afterslip” in the days to years following an earthquake.

Detailed explanation-5: -Other examples of faults that have experienced aseismic creep include the San Andreas Fault in California and the North Anatolian Fault in Turkey. Creep along the Maacama Fault is about 8 mm per year, consistent with the steady movement along the rest of the Hayward Fault system.
