Abstract: | Comparison between observed and theoretical seismic intensities of the Messina earthquake of 1908 shows an area of negative anomalies, which seems to correspond to the «shadow» of the Etna magma chamber. This magma chamber has probably an elongated form, being 40 km wide and about 100 km long; the mean depth appears to be close to 5 km, but the thickness cannot be estimated from the present data. |
