The scientific life of Luigi Palmieri 100th Anniversary commemoration(21/04/1807-09/09/1896)

I present here a commemoration of the scientific life of Luigi Palmieri, II Director of the Osservatorio Vesuviano. His research on both volcanic and tectonic phenomena was supported by his development of the first electromagnetic seismograph, which he also built in a "portable" version. He had the intuition to relate seismic activity to eruptive episodes, and, in this sense, he was the first scientist to imagine the eruption forecast in a modern way.
