A 5.4-magnitude earthquake jolted northwest China's Qinghai Province at 10:15 p.m. on June 10, according to the China Earthquake Network Center.

The quake struck the Tanggula Range within the Haixi Prefecture of Qinghai, with the epicenter at 33.2 degrees north latitude and 92.0 degrees east longitude, the center reported.

Earlier the same day, the region had been struck by two other tremors with similar magnitude.

A 5.1-magnitude earthquake hit at 7:04 p.m. and a 5.5-magnitude one hit at 6:04 p.m.

According to the center, the affected area is sparsely populated as it is on an altitude of about 5,000 meters above sea level.

Also on June 10, a 5.2-magnitude quake rocked the northern Inner Mongolia Autonomous Region at 2:05 p.m.

Crashed Helicopter Found

Searchers have found the remains of a missing Chinese helicopter and its passengers in the mountains near Yingxiu, a town close to the May 12 earthquake's epicenter, on the 10th day of their search. The debris of the Mi-171 helicopter was found in the bushes northwest of Yingxiu Township on June 10.

Five crewmembers and 13 quake victims were found dead at the crash site. The helicopter went down on May 31 while transferring local residents from the epicenter of the quake in the southwestern province of Sichuan.

More than 100 helicopters were sent to locate the chopper, while more than 300 rescue teams, consisting of over 10,000 troops, armed police, militia, reservists and local residents, combed the region to search for the missing aircraft.

Panda Found Dead

A nine-year-old female giant panda that had lived at the Wolong reserve was confirmed dead as a result of the May 12 earthquake, with her body retrieved and buried.

Mao Mao was among six pandas who went missing after the quake. The other five were found.

Rescuers found the body in the rubble of the pandas' pens and excavated it on the morning of June 10, said Li Desheng, Vice Director of the Conservation and Research Center of the Wolong Nature Reserve for Giant Pandas.

The Wolong reserve sustained severe damage from a quake-triggered landslide, with the death of five staff and the panda Mao Mao.

Exam Grace Period

The annual national college entrance examination for the 62 quake-ravaged counties and districts in Sichuan and Gansu provinces has been postponed until July 3 to 5, the Ministry of Education said.

The national college exam took place between June 7 and 9 in other parts of the country. A record 10.38 million students participated in the exam, the largest of its kind in the world.

The ministry has allowed a total of 120,000 students in the quake-hit areas a grace period to offset the physical and psychological effects of the 8.0-magnitude quake.

The ministry has also asked colleges nationwide to offer an extra 2 percent of placements to candidates from Sichuan.

Largest Manmade Forest

Thanks to years of forestation efforts, the acreage of China's man-made forests now exceeds 53.4 million hectares, ranking first in the world, the State Forestry Administration (SFA) announced.

The country's forest coverage has risen to 18.21 percent of the total land area, from 8.6 percent in the early 1950s, an official from the SFA said at a forum on desert control and ecological civilization in Guizhou Province, southwest China.

Earlier, the SFA revealed in its 2007 Green Coverage Report that ordinary Chinese people had planted 51.54 billion trees in the past three decades.
