Answer:
seismometers and the tilt meters, creep meters.
Step-by-step explanation:
- For monitoring the faults the geologist use to measure the elevation of land by the wires that stretched across the fault to measure the horizontal movement of the ground.
- As the active faults have to be measured with the relative motion of the earth. The fault zone gets stuck up and locked up which indicates the tilting of the surface features that results in the lack of tiling around a fault.
- The tiltmeters have a sensitive inclinometer that is designed to measure small changes in the earth like the dams or the monitoring of the volcanic zones.
