Unfortunately, another devastating earthquake has stuck China killing at least 50 people. That number is expected to be on the rise after sorting off through the damage area. Rescuers are making their way into the rubble, but the damage is keeping them from reaching outlying areas. The quake started with a 5.6-magnitude shock. Click below to read more.

The quakes started with a 5.6-magnitude shock before 11:30 a.m. along the borders of Guizhou and Yunnan provinces, and another equally big quake struck shortly after noon followed by more than 60 aftershocks, Chinese and U.S. government seismologists said. Though of moderate strength, the quakes were shallow, which often causes more damage.

Hardest hit was Yiliang County, where 49 of the 50 deaths occurred, said Yunnan province government agencies and state media. Another 150 people in the county were injured, said Zhang Junwei, a spokesman for the provincial seismology bureau.

China Central Television showed roads littered with rocks and boulders, and pillars of dust rising over hillcrests — signs of landslides. Footage showed a couple hundred people crowding into what looked like a school athletic field in Yiliang’s county seat, a sizeable city spread along a river in a valley bottom.

With some roads impassable, rescuers had yet to reach some outlying villages and towns, the official Xinhua News Agency said.

Though quakes in the area occur frequently, buildings in rural areas and China’s fast-growing smaller cities and towns are often constructed poorly. In 2008, a magnitude-7.9 quake that hit Sichuan province, just north of Yunnan, killed nearly 90,000 people, with many of the deaths blamed on poorly built structures, including schools.

Xinhua said Friday’s quakes destroyed or damaged 20,000 homes. The Yunnan seismology bureau said and more than 100,000 people were evacuated from their homes. All told, Xinhua said, 700,000 people had their lives disrupted by the quake.

In Luozehe, a town in Yiliang near a zinc mine, residents and state media said boulders hurtled off hillsides and houses collapsed.

Mobile phone services were down and regular phone lines disrupted. Phones were cut off to clinics in four villages in Qiaoshan, another town in Yiliang, which has about half a million people.

Xinhua said thousands of tents, blankets and coats were being shipped to the area.

Friday’s quakes were relatively shallow, about 6 miles or 10 kilometers deep, creating an intense shaking even at a lower magnitude.

By comparison, the 7.6-magnitude quake that struck Costa Rica this week was 25 miles (41 kilometers) below the surface, and combined with strict building codes, that kept damage and deaths to a minimum.
