The first seismographs were invented by a Chinese man, Zhang Heng, in the second century around 132 A.D (After Christ)
Heng's prototype considered of a cylinder with balls attached that it detected movement beneath the earth and alerted Heng by falling off.
It was decorated with Chinese Dragons, the balls exiting from the mouths of the legendary dragons and into the mouths of frogs who were facing the direction of the quake. This idea was then develouped by John Milner in 1880 who invented the first MODERN seisomete......
These archaic seismographs were succeeded by electrical seismometers in the 1850s. Luigi Palmieri was an Italian inventor who responded to the plethora of earthquakes in his country by fashioning a device based on the scientific principles associated with the barometer.
Palmieri's invention worked when a tremor beneath the earth created an electrical reaction between Mercury and an electric switch. The electrical impulse serve to stop the ticking of an attached clock at the exact second that the tremor took place. The device was also fashioned to determine the intensity of the earthquake, as well how long the quake lasted.
