Question

Give an account of major earthquakes and their causes in Uttarakhand.

Hint:

Remember: The major cause of earthquakes in Uttarakhand is the tectonic plate collision in the Himalayan region, especially along the major faults like MBT and MCT.

Answer 1

Step 1: Overview of Earthquakes in Uttarakhand.
Uttarakhand, located in the northern part of India, is a seismically active region due to its position in the Himalayan belt, which is prone to tectonic activity.
Step 2: Causes of Earthquakes in Uttarakhand.
The primary cause of earthquakes in Uttarakhand is the collision of the Indian Plate with the Eurasian Plate. This leads to the formation of the Himalayan mountain range, and the tectonic movement causes seismic activity in the region.
Step 3: Faults and Seismic Zones.
Uttarakhand is located in seismic zones IV and V, which are highly prone to strong earthquakes. The movement along major faults such as the Main Boundary Thrust (MBT) and the Main Central Thrust (MCT) further triggers earthquakes.
