In Himachal, in the last one and a half months, more than 35 people died in the slipping hills. Whereas in the Joshimath, Devprayag, and Tehri districts of Uttarakhand, property worth crores have been damaged due to heavy landslides at many places. Geologists believe that rain is just an important factor in these creaking mountains. The real reason is small earthquakes that occur continuously every day in the entire Himalayan belt.
Small earthquakes have occurred in Uttarakhand and Himachal more than 130 times in the last five years. These earthquakes are less than Richter three. These frequent earthquakes do not cause huge loss of life and property in an instant, but they disturb the Himalayan Thirst Belt.
Director-General of Uttarakhand Satellite Space Center and Senior Geoscientist Dr. Prof MPS Bisht explains that the Himalayas are the newest mountain ranges in the world. The frequent earthquakes, which are not even felt much, contribute significantly to the dispersion of rocks. Most such earthquakes occur in Uttarakhand and Himachal.
Senior seismologist and HOD of Geophysics Department at Wadia Institute of Himalayan Geology, Dr. Sushil Rohela explains, "Six Ex-chlorograph and seismographs have been installed in Himachal and Uttarakhand for research on these small earthquakes. Due to these earthquakes, the cracks are more and when it rains, when the water fills them, then there is a big landslide. Scientists have therefore been advising governments to avoid development works under human activities in the higher regions of the Himalayas.
According to the research of Wadia Institute of Himalayan Geology, earthquakes up to Richter 3 every day in the entire Himalayan belt indicate the risk of major earthquakes in the future. Senior Seismologist Dr. Sushil Rohela explains that small earthquakes are often preceded by large earthquakes, which are in the range of six to eight on the Richter scale. Due to frequent small earthquakes, the thrust plate moves. Because of this, when there is more space in them, then there is a possibility of a big earthquake.
