Question

Why are the shiwaliks,earthquake prone zones.

Answer 1

Shiwaliks is made up of unconsolidated sediments and is the lowermost part of Himalayas. It is found near river valleys which erodes the soil and hence prone to landslides. It is also located near the boundary of a tectonic plate and hence more prone to earthquakes..

Answer 2

The shiwaliks ranges are still in the process of folding. This is the the youngest range of the Himalayas formed by unconsolidate rock material. Therefore these ranges are prone to earthquake and landslides.
