Magnitude 7.0 Earthquake Strikes Remote Region of Northern Tibet

A powerful magnitude 7.0 earthquake struck a remote, high-altitude region of northern Tibet late Thursday, shaking communities that sit at some of the highest elevations on Earth.

The earthquake hit at about 10:33 p.m. local time on Thursday, Oct. 22, which was 10:33 a.m. EDT, according to the China Earthquake Networks Center. Its epicenter was in Baqen County, in Tibet’s Nagqu region, roughly 250 miles north of the regional capital, Lhasa.

Shaking was clearly felt in the local area. In the hours after the quake, there were no immediate reports of injuries, deaths or damage.

What We Know So Far

Early measurements of the earthquake differ slightly depending on the agency. The China Earthquake Networks Center reported that the quake originated about 6 miles, or 10 kilometers, beneath the surface, making it a shallow earthquake.

The U.S. Geological Survey also measured the quake at magnitude 7.0, but placed its depth at about 11 miles, or 18 kilometers. The USGS located the epicenter about 119 miles east-northeast of the city of Nagqu, in a sparsely populated, high-altitude area.

Differences like these are common in the first hours after a major earthquake. Agencies use different networks of seismic instruments, and their estimates are often refined as more data comes in.

Why the Location Matters

The epicenter’s remote location may have worked in the region’s favor. Northern Tibet is one of the most sparsely populated areas in China, with small communities spread across a vast, mountainous plateau.

Shallow earthquakes tend to produce stronger shaking at the surface than deeper ones of the same magnitude. In a more densely populated area, a magnitude 7.0 quake at this depth could cause widespread damage. Here, fewer people and buildings sit close to the epicenter.

Still, the region’s isolation can make it harder for emergency crews to reach affected communities and assess damage. Remote roads, high elevations and cold late-October nights can all complicate the response.

Emergency Response Underway

Chinese authorities moved quickly after the earthquake. The China Earthquake Administration activated a level-II emergency response, according to a brief report from the state news agency Xinhua.

Officials have not yet released detailed information about damage to homes, roads or other infrastructure. Assessments in remote areas can take time, so more information is likely to emerge in the coming days.

Aftershocks are also common after a major earthquake, and they can continue for days or even weeks. Strong aftershocks can cause additional damage, especially to buildings already weakened by the initial quake.

A Region With a History of Strong Earthquakes

Tibet sits on one of the most seismically active regions in the world, where the Indian tectonic plate pushes north into the Eurasian plate. That ongoing collision created the Himalayas and the Tibetan Plateau, and it continues to produce powerful earthquakes.

Thursday’s quake comes less than two years after a deadly earthquake in another part of Tibet. In January 2025, a magnitude 7.1 earthquake struck Tingri County, near Mount Everest, killing at least 126 people, according to Chinese state media. Residents said poorly built homes near the epicenter contributed to the high number of casualties.

For now, officials and residents in northern Tibet are waiting for a clearer picture of how hard the region was hit, as rescue and assessment teams work through the night.
