The displacement field caused by the classic earthquake mechanism model consisting of a slip along the fault is extended to the case when besides the slip, also an opening occurs caused by tensional forces. The tensor matrix describing the moment tensor does not necessarily have a nil trace. The direct problem is solved finding the radiation pattern for and waves. A method to solve the inverse problem of the determination of the four parameters describing the source is presented and tested on...

Assumendo la validità del modello secondo il quale ogni terremoto può essere rappresentato su un piano delle fasi , si studiano le conseguenze dei risultati ottenuti in un precedente lavoro circa la distribuzione statistica dei terremoti sul piano stesso. Si giunge alla conclusione che l'energia elastica liberata complessivamente dai terremoti è la stessa per ogni elemento
del piano , ed inoltre che il calore prodotto dai terremoti nell’intervallo non dipende da .
