Tangshan：The Deadliest Earthquake
Fireballs and Animals Give Warning
Thugh scientific earthquake predictin is in its nascent（初期的） stages，nature ften gives sme advance warning f an impending（即将发生的） earthquake.
In a village utside f Tangshan，well water reprtedly rse and fell three times the day befre the earthquake. In anther village，gas began t sput（喷出） ut the water well n July 12th and then increased n July 25th and 26th.Other wells thrughut the area shwed signs f cracking.
Animals als gave a warning that smething was abut t happen.
One thusand chickens in Baiguantuan refused t eat and ran arund excitedly chirping. Mice and yellw weasels were seen running arund lking fr a place t hide. In ne husehld in the city f Tangshan，a gldfish began jumping wildly in its bwl. At 2 a.m. n July 28th，shrtly befre the earthquake struck，the gldfish jumped ut f its bwl. Once its wner had returned him t his bwl，the gldfish cntinued t jump ut f its bwl until the earthquake hit.
Strange？Indeed. These were islated incidents，spread acrss a city f a millin peple and a cuntryside scattered with villages. But nature gave additinal warnings.
The night preceding the earthquake，July 27th-28th，many peple reprted seeing strange lights as well as lud sunds. The lights were seen in a multitude f hues. Sme peple saw flashes f light；thers witnessed fireballs flying acrss the sky. Lud，raring nises fllwed the lights and fireballs. Wrkers at the Tangshan airprt described the nises as luder than that f an airplane.
Earthquake and Quakeprf
Sme cuntries，such as Japan，have a large number f earthquakes. Earthquakes happen very quickly and vilently. During an earthquake，there is ften a great nise first. Then the earth shakes terribly；many huses fall dwn；railwayy tracks break and trains run ff lines；a great many factries are destryed；thusands f deaths are caused，and many mre lse hmes. Besides the great damage and deaths caused by the earthquake itself，ther disasters such as fires ften fllw，mre building destryed and mre deaths caused.
It is well knwn f the dangers f a pssible earthquake，and fr centuries man has been making researches n earthquake. Mre than 2000 years ag，fr example，a Chinese scientist named Zhang Heng invented a machine which culd detect earthquakes，and this machine is still used by scientists tday t detect and measure the strength f earthquakes. Nw we knw much mre abut earthquakes and why they happen，but we still cannt tell exactly when and where an earthquake will happen，and cannt stp it frm happening. S earthquakes are amng the wrst disasters in the wrld.
N ne can stp natural earthquakes. Hwever，scientists can help stp earthquakes destrying whle cities and causing t many deaths. In thse areas where earthquakes ften happen，they recrd muntain temperatures and take phts frm the air and if anything starts t happen，they warn gvernments t be prepared fr pssible disasters s that emergency plans are put int actin t lessen the disaster，prbably saving many lives.
