Summary

A seismic network, based on newly designed and assembled equipments, has been set up in the Travale geothermal field, South-West of the Era graben, and explosions have been produced on the opposite edge of the graben (in the Montagnola Senese region) by 5 successive seismic energy steps.

Obscured arrivals in almost all recording stations are inferring absence of structural connections between the edges that are likely rigid at shallow depths. If so, new arguments have to be taken into account for substantiating several interpretations that seemed quite established.
