Original printed wrappers, corners of lower cover torn. An excellent copy, partly unopened; upper and lower margins somewhat browned. In 1883, after the catastrophic earthquake occurred in the island of Ischia that destroyed the town of Casamicciola, causing over 2,300 deaths, was officially founded the Central Geodynamic Observatory and Archive, at the Geological Service, directed by De Rossi. In 1887 it branched out with the Italian Central Meteorological Office, created in 1876, becoming the Central Office for Meteorology and Geodynamics.
