The seismic sequence of Comino valley

Bechyne - Prague (Czech Rep.)

IN this paper some remarks the Comino valley seismic sequence, occurred in Central Italy on 7 May 1984 with a main shock of Md 5.4, are presented. The sequence, occurred in a seismic zone,was characterized by absence of foreshocks. Some characteristics of the sequence underline the coupling between the cumulative frequency vs time trend and the modality of a Kelvin's solid strain release which has a time relaxation of about 30 days. Furthermore we analyse b-value and Gutenberg relation to evaluate the enrgy release.
