Churachandpur-Mao Fault (CMF)

  • The CMF is named after two places in Manipur and runs north-south into Myanmar along the border of Champhai.
  • The Mat Fault runs northwest-southeast across Mizoram, beneath river Mat near Serchhip.
  • It is defined by straight valleys; most prominent being between Kangpokpi and Maram region of Mizoram.
  • The fault takes a north-easterly trend from Maram where the fault zone is characterized by active landslides during the monsoon.

Why study CMF?

  • Faults are discontinuities or cracks that are the result of differential motion within the earth’s crust.
  • Vertical or lateral slippage of the crust along the faults causes an earthquake.
