| Abstrakt: | This paper presents a case study of the "electric hypothesis" of the causes of earthquakes, which emerged in the second half of the eighteenth century as part of the first studies of seismology. This hypothesis was related to Franklin's views on atmospheric electricity and developed in a period when electric phenomena were widely studied, and was essentially based on solid empirical evidence and confirmed by model experiments. Even though it resulted from scientific reasoning, the theory remained strongly empirical, and was supported by Italian scholars who were familiar with seismic events. Among these, Giuseppe Saverio Poli, a follower of Franklin, was able to provide a careful and comprehensive explanation of the disastrous earthquake of 1783, which occurred in Calabria, a region of southern Italy, and the St. Anne earthquake of 1805, by drawing not just upon the electric evidence, but all the relevant phenomenology available. We outline here the emergence, the development, and the later evolution (up to the beginning of the nineteenth century) of the "electric earthquake" paradigm by focusing on different works by Poli, including a previously unknown manuscript containing a thorough account of the Calabria earthquake prepared by the Neapolitan scholar for the Royal Society. The present case study therefore offers the opportunity to illustrate how electrical science shaped earthquake science to a degree not usually appreciated in the literature, and is also supported to some extent by the transition from Enlightenment scientific ideals to the Romantic conception of unity in the natural world, in search of common causes among phenomena belonging to different fields.
