the earthquake in WenChuan
On Monday,an earthquake in China measuring 7.9 on the Richter scale occurred along a fault where south Asia pushes against the Eurasian Landmass,smashing the Sichuan Plain into mountains,leading to the Tibetan highlands.
In 1989,the Loma Prieta Earthquake shook the San Francisco and Monterey Bay regions.This major earthquake caused dozens of deaths,thousands of injuries,and an estimated 6 billion dollars in property damage.It was the largest earthquake to occur on the San Andreas Fault since the great San Francisco earthquake in April 1906.
The Loma Prieta quake was similar to Tuesday’s earthquake in China in depth,but its magnitude was just 7.1 on the Richter scale,compared to the Sichuan quake at 7.9.
Seismology experts in Japan also compared the earthquake to the Kobe quake of 1995 in Japan,in which more than 5,000 were killed.
"Because earthquake occurred in shallow that is about 10 kilometers beneath the ground,so the damage is usually very strong and devastating.If you remember the Kobe earthquake in 1995,this is,in a sense,in similar type,because earthquake is shallow and right beneath the land and population area."
The professor also warned that aftershocks could cause further damage in the region of the quake.USGS seismologists warn that aftershocks from this earthquake could be felt up to 16 miles from the epicenter and could last for months.

以‘汶川地震’为题,
在文中讲述了世界各地发生的地震,有旧金山,洛马普利塔,日本
倒数第二段说的是地震发生的方式,来说明地震具有很强的破坏力.
最后要人们做好震后预防工作,预防余震.

说的是5.12汶川大地震
有拿出1989年的旧金山地震相比较收损的程度！以及救援的情况！
