News: Wadia Institute of Himalayan Geology(WIHG) has conducted a study pertaining to the Arunachal Himalaya which has revealed that the area is generating moderate earthquakes at two different crustal depths.
Important Terms Related to the Study:
- Tuting-Tidding Suture Zone(TTSZ): It is a major part of the Eastern Himalaya where the Himalaya takes a sharp southward bend and connects with the Indo-Burma Range.
- This part has gained importance due to growing need of constructing roads and hydropower projects emphasising the need for understanding the pattern of seismicity in this region.
- Mohorovicic or Moho Discontinuity: It is the boundary between the crust and the mantle.In geology, the word discontinuity is used for a surface at which seismic waves change velocity.
