Magnitude 5.5 Earthquake Strikes China Near Source of Yellow River

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.

In the skies above Los Angeles, air tankers and helicopters silhouetted by the setting California sun dart in and out of giant wildfire plumes, dropping much-needed flame retardant and precious water onto the angry fires below.
Looking in almost any direction from a chopper above the city, AFP reporters witnessed half a dozen blazes -- eruptions of smoldering smoke emerging from the mountainous landscape like newly active volcanoes, and filling up the horizon.
Within minutes, a previously quiet airspace above the nascent Kenneth Fire had become a hotbed of frenzied activity, as firefighting officials quickly refocused their significant air resources on this latest blaze.
Around half a dozen helicopters buzzed at low altitude, tipping water onto the edge of the inferno.
Higher up, small aircraft periodically guided giant tankers that dumped bright-red retardant onto the flames.
"There's never been so many at the same time, just ripping" through the skies, said helicopter pilot Albert Azouz.
Flying for a private aviation company since 2016, he has seen plenty of fires including the deadly Malibu blazes of six years ago.
"That was insane," he recalled.
But this, he repeatedly says while hovering his helicopter above the chaos, is "crazy town."
The new Kenneth Fire burst into life late Thursday afternoon near Calabasas, a swanky enclave outside Los Angeles made famous by its celebrity residents such as reality television's Kardashian clan.
Aircraft including Boeing Chinook helitankers fitted with 3,000-gallon tanks have been brought in from as far afield as Canada.
Unable to fly during the first few hours of the Los Angeles fires on Tuesday due to gusts of up to 100 miles (160 kilometers) per hour, these have become an invaluable tool in the battle to contain blazes and reduce any further devastation.
Helicopters performed several hundred drops on Thursday, while conditions permitted.
Those helicopters equipped to operate at night continued to buzz around the smoke-filled region, working frantically to tackle the flames, before stronger gusts are forecast to sweep back in to the Los Angeles basin overnight.
