Zhang Heng was a famous scientist in the history of China. His invention Hou Feng Seismometer was a great success and it helped us understand the world better.


(AD 78-139)

                      It was invented.
Zhang Heng was born in Nanyang in the eastern Han Dynasty. At that time, there were many earthquakes every year. People thought they were from ghosts. Zhang Heng, however, didn’t believe it. He tried to find ways to study earthquakes for many years and in 132 he invented the first seismometer in the world.
It was used.
But at first, people didn’t believe it and all laughed at him. In February, 138, Zhang heng’s seismometer told there was an earthquake in the west of Luoyang. After four days, three earthquakes really happened in Luoyang area. It was believed to be useful from then on. However, it was lost 1700 years ago.
It was reproduced.
Scientists have been trying to reproduce one like that. In 2012, the latest reproduced seismometer was successfully listed in Shanghai museum. It was reported to have been a little helpful during the earthquakes in Tangshan, Yunnan and Sichuan. It is hoped to be improved better soon and be able to predict coming earthquakes one day.

 Earthquakes are common, and thousands of them happen each day.  But most are too weak to feel. During a   earthquake, there is often a great noise first.  Then the earth   terribly and many houses    down.  Railway tracks break and trains go off lines. A great many factories are destroyed. Thousands of deaths are caused, and many more lose homes.  Besides the great damage and deaths caused by the earthquake   ,other accidents such as fires often     . More buildings are destroyed and more deaths caused. It is well-known of the   of an earthquake, and for centuries man has been making researches on earthquakes. More than 2,000 years ago,  ,a Chinese scientist named Zhang Heng invented a machine which could     from which direction the seismic waves(地动波)had come, and this machine is still    by scientists today. Now we know much more about earthquakes and   they happen, but we still can't tell exactly when and where earthquake will happen,  and cannot stop it from happening.
