Fifty people died, over 11,000 were injured, and 100,000 houses were heavily damaged or destroyed in an earthquake that struck North China's Hebei Province.
The quake, measuring 6. 2 on the Richter scale (里氏6 .2级) , hit the area 220km northwest of Beijing at 11: 50 a. m. on January 10, 1998.
Scientists made a report of the recent quake. They said that the area of northwestern Beijing, the joint of Shanxi and Hebei Provinces and the Inner Mongolia (内蒙古) were most easily attacked by earthquakes measuring 6 to a bit over 7 on the Richter scale.
However, scientists did not see the recent earthquake earlier. Clouds covered a large area in the northern part of North China before the earthquake and experts say that this prevented satellites from correctly watching the temperature at the correct altitude (纬度).
Experts say that in the last ten years, about 305 earthquakes have taken place in China with 9 measuring over 7 on the Richter scale, 60 measuring over 6, and 236 measuring over 5.
Tens of thousands of people died or were injured. Loss(损失) valued over 10 billion yuan.
