A thrust fault is a type of reverse fault that has a dip of 45 degrees or less if the angle of the fault plane is lower often less than 15 degrees from the horizontal and the displacement of the overlying block is large often in the kilometer range the fault is called an overthrust or overthrust fault. Geology a fault in which the hanging wall has moved upward relative to the footwall. A reverse fault if steeply dipping or thrust fault if shallowly dipping is a fault where the fault plane dips toward the upthrown block. Thrust faults are reverse faults, but specifically they are reverse faults that happen during compression, when plates or portions. Britain has, in the past, had many active faults and many earthquakes, but very few faults are active today, so strong earthquakes are rare. If a relay uses z 1,relay for sensing direction to fault, the z 1,relay measurement will see balanced load flow as an indication of the direction to fault and, hence, to turn on overcurrent elements 6751 that are set to look in the direction of present 1.

The difference between the two faults is the angle of the fault. A reverse fault is any fault in which the hanging wall that is, the fault block that is above the plane of the fault is elevated relative to the foot wall, which is the fault block below the plane of the fault. Nearly all faults will have some component of both dipslip normal or reverse and strikeslip, so defining a fault as oblique requires both dip and strike components to be measurable and significant.
