fault block
A fault with little or no vertical movement is called a strike-slip fault. In this type of fault, the rocks on either side of the fault move horizontally past each other, usually in a side-to-side motion. This movement can cause earthquakes when the stress along the fault overcomes friction and the rocks suddenly slip.
When a fault is not vertical, a hanging wall and footwall are formed. The hanging wall is the block of rock above the fault plane, while the footwall is the block of rock below the fault plane. These terms help geologists describe the displacement and movement along the fault.
The offset along a fault is the distance by which one side of the fault has moved in relation to the other side. This movement can be horizontal, vertical, or a combination of both, and it is a measure of the displacement that has taken place along the fault.

GPS and interferometric synthetic aperture radar monitor both vertical and horizontal movements along the fault.
In a dip-slip fault, the movement is primarily vertical along the fault plane, either up (reverse fault) or down (normal fault). In a strike-slip fault, the movement is primarily horizontal along the fault plane, with minimal vertical movement. Both types of faults are caused by tectonic stresses in the Earth's crust.
vertical direction
A seismometer is an instrument used to measure vertical movement along faults. It detects and records ground motion caused by seismic waves generated by earthquakes or other sources. The data collected from seismometers can provide valuable information about fault activity and earthquake potential.

A fault is a fracture in the Earth's crust where movement has occurred. This movement can be horizontal, vertical, or a combination of both. Faults can generate earthquakes when the stress along the fault is released suddenly, resulting in movement along the fault surface.
A seismometer, which is a device that measures ground movements, can detect both vertical and horizontal movements along a fault. These instruments are crucial for monitoring seismic activity and predicting potential earthquakes.
When a fault is not vertical, a hanging wall and footwall are formed. The hanging wall is the block of rock above the fault plane, while the footwall is the block of rock below the fault plane. These terms help geologists describe the displacement and movement along the fault.
A strike-slip fault involves horizontal movement along the fault plane, where rocks on opposite sides slide past each other horizontally.
