Dr Harsh Vardhan, Union Minister for Health & Family Welfare, Science & Technology, Earth Sciences :

• A seismicity study conducted by Wadia Institute of Himalayan Geology under the Department of Science & Technology, has revealed that Arunachal Himalayas are generating low to moderate earthquakes at two different crustal depths.
• Low magnitude earthquakes are concentrated at 1-15 km depth & slightly higher (greater than 4.0) magnitude earthquakes are mostly generated from 25-35 km depth. The intermediate-depth is devoid of seismicity & coincides with the zone of fluid/partial melts
• Researchers installed 11 broadband seismic stations along Lohit River Valley of the Arunachal Himalayas to understand elastic properties of rocks & seismicity in easternmost region They used both teleseismic & local earthquake data with the help of seismometers
