It was also meant to measure the size of an earthquake. During an earthquake, ground-shaking seismic waves radiate outward from the quake source, called the epicenter. It has been replaced in time by a horizontal pendulum, sustained from soft with which is possible to build tools of reduced dimension and high sensitivity. They are held in a very solid position, either on the bedrock or on a concrete base. Ancient peoples had many fanciful explanations for earthquakes, Meanwhile, in Italy, Luigi Palmieri invented an electromagnetic seismograph that was the first seismic instruments capable of detecting earthquakes imperceptible to human beings. He was famous for h.

When the ground shakes, the frame vibrates also, but the mass tends not to move, due to inertia. Luigi Palmieri (Faicchio 1807 -Naples 1896), was appointed Director of the Vesuvius Observatory in 1855. The first systematic observations of the correlations existing between seismic activity and volcanic eruptions were probably those carried out at Mt. Although pendulums were used to detect the ground motion due to earthquakes at the beginning of the 19th century, the earliest seismographs were those developed in Italy by Luigi Palmieri (1807-1896) in 1855 and by Timoto Bertelli (1826-1905) in 1872.
