Seismograph: Saving Lives From An Earthquake

The seismograph influenced the world and madeJust as this impact sets waves in motion on a quiet pond, so an earthquake generates seismic waves that radiate out through the Earth.” It easier to save lives from an earthquake. It warns people when to get out of that city or state.”Obviously this can show how a siesmograph works and can save many lives.How it works is that it detects a siesmic wave.”seismic detectors into networks that halt bullet trains, close valves at manufacturing plants and even send voice messages to cell phones warning that serious shaking is about to occur.”Clearly this shows how a siesmograph can save someones life fom an earthquake in seconds.”If you are close to the earthquake, the P and S wave will come one right after the other, but if you are far away, there will be more time between the two.Not only does a seismograph show when an earthquake is about to happen but also can show where the earth quake is happening,which could be coincidental help with trying to save as many people from an earthquake as possible.As can be …show more content…
It warns people when to get out of that city or state. Also the seismograph has lots of history behind it too. However,there were many things that worked like the ordinary seismograph,but were too complicated. Then finally a man named Filippo Cecchi -in 1875 came up with the first true seismograph. The very first seismograph was produced in 132 CE and made by Zhang Heng. His Seismograph was very unique. It had eight dragons around the center of the first type of seismograph and eight frogs at the bottom of the seismograph that would catch the balls in their mouths. Then the seismograph would make a sound to let people know there is an earthquake approaching.Zhang Heng's then lead up to another invention in 1855 and was made by Luigi Palmieri.The device was able to find the moment of the shaking and the duration of the
