Recent findings:
A recent study has indicated that Mizoram is caught between two subterranean faults– Churachandpur Mao Fault and Mat Fault.
- Churachandpur Mao Fault runs north-south into Myanmar along the border of Champhai.
- Mat Fault runs northwest-southeast across Mizoram, beneath the river Mat near Serchhip.
There are several shallower transverse or minor faults in between these two major faults that are deeper.
What is a fault?
A fault is a thin zone of crushed rock separating blocks of the earth’s crust. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
- Faults can be centimeters to thousands of kilometers long.
- The fault surface can be vertical, horizontal, or at some angle to the surface of the earth.
- Faults can extend deep into the earth and may or may not extend up to the earth’s surface.
