A magnitude 5.5 earthquake shook parts of the Chinese province of Qinghai on Wednesday, with its epicenter located near the source of the Yellow River, the main natural waterway serving northern China.

The vast Qinghai-Tibetan plateau has been jolted by seismic activity since Tuesday, including a deadly 6.8-magnitude quake in the foothills of the Himalayas in Tibet and a smaller 3.1-magnitude quake in Sichuan.

The epicenter of the Qinghai quake, which struck at 3:44 p.m. (0844 GMT), was located in Madoi county in the Golog prefecture at a depth of 14 km (8.7 miles), according to the China Earthquake Networks Center (CENC).

It was about 200 km west of the county seat of Madoi, a town populated mainly by Tibetans, including former nomadic herders and their families who have resettled in government-built homes over the years.

Earthquakes are common along the edges of the seismically active Qinghai-Tibetan plateau, including Madoi.

A total of 102 quakes of magnitude 3 or higher have been logged within 200 km of Wednesday's quake over the past five years, according to CENC, with the largest reaching a magnitude of 7.4 in 2021.

The epicenter of Qinghai quake on Wednesday is about 1,000 km northeast of the quake in Tibet a day earlier.

Chinese health authorities said on Thursday they had detected the new mutated mpox strain clade Ib as the viral infection spreads to more countries after the World Health Organization declared a global public health emergency last year.
China's Center for Disease Control and Prevention said it had found a cluster outbreak of the Ib subclade that started with the infection a foreigner who has a history of travel and residence in the Democratic Republic of the Congo, Reuters reported.
Four further cases have been found in people infected after close contact with the foreigner. The patients' symptoms are mild and include skin rash and blisters.
Mpox spreads through close contact and causes flu-like symptoms and pus-filled lesions on the body. Although usually mild, it can be fatal in rare cases.
WHO last August declared mpox a global public health emergency for the second time in two years, following an outbreak in the Democratic Republic of Congo (DRC) that spread to neighboring countries.
The outbreak in DRC began with the spread of an endemic strain, known as clade I. But the clade Ib variant appears to spread more easily through routine close contact, including sexual contact.
The variant has spread from DRC to neighboring countries, including Burundi, Kenya, Rwanda and Uganda, triggering the emergency declaration from the WHO.
China said in August last year it would monitor people and goods entering the country for mpox.
The country's National Health Commission said mpox would be managed as a Category B infectious disease, enabling officials to take emergency measures such as restricting gatherings, suspending work and school, and sealing off areas when there is an outbreak of a disease.
