Powerful Earthquake Near Mount Everest Kills 126 in Tibet; Seismic Causes Explained
A devastating earthquake struck Tibet’s Tingri County, near Mount Everest, early Tuesday, killing at least 126 people and injuring over 180. The quake, recorded at 6.8 magnitude by Chinese authorities and 7.1 by the US Geological Survey, occurred at 6:35 am, about 80 km north of the mountain. Tremors were felt across Nepal, Bhutan, and parts of India.
The earthquake was triggered by a rupture in the Lhasa block, a region under immense tectonic stress due to the ongoing collision between the Indian and Eurasian tectonic plates. This process, which has shaped the Himalayas over the past 60 million years, makes the area a hotspot for seismic activity.
Tibet has experienced numerous major earthquakes, including a magnitude 8.6 quake in 1950. Recent studies suggest that the Indian plate is slowly peeling apart beneath Tibet in a phenomenon known as “slab tearing.” This occurs when the upper crust of the Indian plate detaches from its denser lower layer, creating deep seismic disturbances.
While this tearing process could theoretically divide Tibet into two distinct sections, it is unlikely to produce visible surface cracks. The phenomenon happens deep beneath the Earth’s surface and significantly influences seismic activity. Scientists are investigating this tectonic behavior by analyzing earthquake waves, deep-layer seismic events, and gas emissions to better understand its potential long-term impact.
Himalayan Region Faces Growing Seismic Risks as Plate Collision Intensifies
The Himalayas, one of the world’s most geologically active zones, have a long history of devastating earthquakes. Scientists warn that the ongoing collision of the Indian and Eurasian tectonic plates continues to heighten seismic risks in the region.
On Tuesday, powerful tremors were felt as far as Kathmandu, Nepal, located 400 km from the epicenter. Despite the intensity, Nepal reported no casualties.
Chinese President Xi Jinping has called for comprehensive efforts to minimize casualties and ensure the proper resettlement of affected communities. Emergency response teams are working to manage the aftermath as aftershocks continue to shake the region. Additionally, China has temporarily closed tourist areas on its side of Mount Everest to prioritize safety.
