Consider the following statements: 1. Himalayan Frontal Thrust (HFT) also known as the Main Frontal Thrust (MFT), is a geological fault along the boundary of the Indian and Eurasian tectonic plates. 2. The Kopili fault zone is a 300 km long and 50 km wide lineament (linear feature) extending from the western part of Manipur up to the tri-junction of Bhutan, Arunachal Pradesh and Assam. Which of the statements given above is/are correct?

The correct answer is Both 1 and 2. In News: ​ Recently, a powerful earthquake measuring 6.4 on the Richter Scale jolted Assam and other parts of the Northeast. Key Points According to the National Centre for Seismology (NCS) report, the tremors have been attributed to the Kopili Fault zone closer to the Himalayan Frontal Thrust (HFT). HFT, also known as the Main Frontal Thrust (MFT) , is a geological fault along the boundary of the Indian and Eurasian tectonic plates. Hence, statement 1 is correct. The Kopili fault zone is a 300 km long and 50 km wide lineament (linear feature) extending from the western part of Manipur up to the tri-junction of Bhutan, Arunachal Pradesh and Assam. Hence, statement 2 is correct. The area is seismically very active falling in the highest Seismic Hazard zone V associated with collisional tectonics where Indian plate subducts beneath the Eurasian Plate. Fault: A fault is a fracture along which the blocks of crust on either side have moved relative to one another parallel to the fracture. When an earthquake occurs, the rock on one side of the fault slips with respect to the other. The fault surface can be vertical, horizontal, or at some angle to the surface of the earth.
