Electronic distance measurements (EDM) represent one of the first methods to detect ground deformation on volcanoes. Used since 1964, they enable acquiring precise distance measurements, whose time repetition may highlight changes related to volcanic activity. This technique was widely used on volcanoes from the 1970s to the early 2000s and has been used many times to model position, geometry, and volumes of magmatic and hydrothermal sources. This paper reports the EDM experiences, results and data acquired on Sicilian volcanoes (Etna, Vulcano, Stromboli and Pantelleria) from the early 1970s, which have played a major role in the birth of the volcano-geodesy for volcanic process knowledge, making the Sicilian volcanoes among those with the longest geodetic record in the world.

电子距离测量 (EDM) 是最早检测火山地面变形的方法之一。自 1964 年开始使用，它们能够获取精确的距离测量，其时间重复可以突出显示与火山活动相关的变化。该技术从 20 世纪 70 年代到 2000 年代初广泛应用于火山，并多次用于模拟岩浆和热液源的位置、几何形状和体积。本文报告了 20 世纪 70 年代初在西西里火山（埃特纳火山、武尔卡诺火山、斯特龙博利火山和潘泰莱里亚火山）进行的 EDM 经验、结果和数据，这些经验、结果和数据在火山过程知识的火山大地测量学的诞生中发挥了重要作用，使西西里火山火山是世界上拥有最长大地测量记录的火山之一。
