本文的研究工作，得到了埃特纳火山下面的一组新的三维速度模型。作者们用１９８０年以来地方性地震在永久和临时地震台网在４个或更多台记录到的１２４９次地震的Ｐ和Ｓ波，被选来作走时反演。选择了几种判别标志与参数化办法以显示其类似的基本特征。表明在火山的东南象限在浅层，有Ｐ波的高速分怖，它同布格重力高异常有密切关系。在该区存在低的Ｖｐ／Ｖｓ比值；沿着中央火山管道，分布有高速Ｐ波和高的Ｖｐ／Ｖｓ比值；建议该处存在有稠密的侵入的岩浆体，延伸到２０千米左右的深度，该区附近有低速的Ｐ波速度。对震源的重新定位也显示出向外倾斜的易碎区，与中央火山管道延伸出一段Ｐ波高速异常区，位于中央火山口的附近。沿着中央火山口附近，有Ｐ波的低速区，它同次生的火山锥的分布有关，与部份熔融的深部岩浆库有联系。
The research work in this paper has obtained a new set of three-dimensional velocity model under Mount Etna. The authors selected P and S waves of 1249 earthquakes recorded on 4 or more sets of permanent and temporary seismographs since 1980 by local earthquakes and were chosen for travel-time inversion. Several discriminant marks and parametric methods were chosen to show similar basic features. It shows that in the shallow layer of the volcano's south-east quadrant, there is high-speed P-wave separation, which is closely related to the high Abnormal gravity of Bouguer. There is a low Vp / Vs ratio in this area. Along the central volcano pipe, high-speed P wave and high Vp / Vs ratio are distributed. It is suggested that there is a dense intrusive magma body extending to a depth of about 20 km There is a slow P-wave velocity near this area. Repositioning of the source also revealed outwardly frangible zones that extended from the central volcanic conduit an area of high P-wave anomalies near the central crater. Along the central crater, there is a low-velocity P-wave zone, which is associated with the distribution of secondary volcanic cones and is associated with a partially molten deep magma reservoir.
