Uttarakhand Tectonic Plate Locked, Study Warns of Massive Earthquake Risk

What Happened

Research shows a 115-kilometre tectonic plate section under Uttarakhand is locked, building up energy that could trigger an 8.1 magnitude earthquake. Scientists from IIT Bombay, the University of New Mexico, and the Central University of Tamil Nadu conducted the study using Global Navigation Satellite System data and Japan's ALOS-2 radar satellite.

Impact on Plains

The Main Himalayan Thrust fault traps the Indian and Tibetan plates as they push against each other at 18 millimetres per year. This pressure causes the upper Himalayas to rise by 4 to 6 millimetres every year. Researchers warn that the resulting seismic waves could reach hundreds of kilometres away, threatening the Indo-Gangetic plains where around 40 percent of India's population lives, including major cities like Delhi, Lucknow, Kanpur, and Patna.

Expert Warnings

While researchers cannot predict the exact date of the earthquake, Wadia Institute of Himalayan Geology geologist Dr. नरेश कुमार states that a 7.5 to 8 magnitude quake in the Himalayas is certain. The study emphasizes that building codes must be strictly followed, old structures surveyed, and disaster management systems strengthened in vulnerable hill and plain regions.

Context

Tectonic plates are massive slabs of Earth's crust that constantly move and interact, often getting stuck at their edges until the accumulated stress suddenly releases as an earthquake. The area in Uttarakhand is known to scientists as a seismic gap because it has not experienced a major earthquake in many centuries, allowing immense pressure to build up over time.
