Abstract

A seismic survey was carried out at Stromboli volcano during August 1973.

Statistical and spectral analyses of volcanic tremor and explosion quakes were performed.

The statistical analysis has shown that the value of them coefficient in Ishimoto & Iida’s relation is high and that the hourly frequencies of events are fairly constant.

The spectral analysis has shown a similarity in shape between tremors and explosion quakes. These events have the dominant frequency of 5 Hz at the craters area.
