Weekly Earthquake Watch — M7.0 Strikes Tibet

The planet had a loud week — and the loudest one hit where almost nobody lives.
On Thursday night, October 22, a magnitude 7.0 earthquake struck a remote stretch of the Tibet Plateau, about 190 kilometers east-northeast of the city of Nagqu. The U.S. Geological Survey measured it at a shallow depth of about 18 kilometers, which tends to amplify shaking at the surface. China's earthquake agency put the epicenter in Baqen County and the depth at 10 kilometers.
The human toll, as of Friday morning: at least 16 people killed and 65 injured, according to China's Xinhua news agency via Reuters. More than 339 houses collapsed. Over 12,000 people were relocated to safety. China's earthquake networks center recorded 413 aftershocks. The USGS issued an orange alert — its second-highest economic-loss warning — and flagged a landslide hazard in the steep terrain. Reuters called it the strongest earthquake to hit China since January 2024.
The Tibetan Plateau is no stranger to this. It sits directly over the collision zone of the Indian and Eurasian tectonic plates, and the energy released there has been building for millions of years. In January 2025, a quake in Tibet's Tingri county killed at least 126 people.
The rest of the week's seismic log
The Tibet quake wasn't the week's only big one. Straight from the public USGS-tracked feeds, for the seven days ending October 23:
- M6.9 — 76 km northeast of Ozernovskiy, Russia (Kamchatka), on October 16. Green alert — deep and remote enough to stay quiet.
- M6.6, M6.3, M6.0 — a swarm off Port-Olry, Vanuatu, on October 19–20. Offshore, unfelt or barely felt.
All told: 380 earthquakes of magnitude 2.5 or greater in the last seven days, 134 of them 4.5 or stronger — and five crossed the M6 line.
The preparedness part
We don't forecast earthquakes here — nobody can. But every week like this is a reminder of the same unglamorous truth: the most useful thing you can own isn't a prediction, it's a go-bag. Water, food for 72 hours, a first-aid kit, a flashlight, copies of your documents — the basics that buy you three days when the ground moves and the trucks can't get through. If this week's log prompts you to check yours, that's the whole point of writing it down.
We read the instruments out loud. That's the job.
