A magnitude 6.3 earthquake hit the northwestern Chinese province of Qinghai on Tuesday, killing at least one person and injuring four, as rescuers rushed to the site ​in search of trapped survivors.

The quake struck a high-altitude area in the ⁠prefecture of Haixi in Qinghai at a depth ​of 10 km at 5:06 p.m. Beijing time on Tuesday, the China Earthquake Networks Centre said.

Initial checks showed transport, communication, water and power lines near the epicenter were operating normally, ​local newspaper Qinghai ‌Daily said late on Tuesday.

Some 320 people are now ‌deployed for the search operation, according to state broadcaster CCTV.

State media previously reported that all workers ⁠at coal mines near ‌the epicenter have ⁠been evacuated and authorities are assessing casualties and property ⁠damage.

The ⁠quake was followed by over a dozen aftershocks including one of magnitude ‌4.9.

Authorities dispatched tents, beds and blankets to quake-hit areas and got companies and charities to provide ‌food and ​water for affected residents.

The ‌epicenter was near Da Qaidam, home to the mineral-rich Emerald Lake, a popular stop ​on the Qinghai-Gansu tourist route.
