The powerful tremors which shook central Italy on Wednesday were the product of a new earthquake rather than aftershocks from one that devastated the town of Amatrice in August, Italian experts say.“It wasn’t an aftershock, it was a new earthquake,” Mario Tozzi of the national institute for environmental geology and geo-engineering (IGAG) told AFP.“What we do not know is whether it was a dormant section of the Amatrice fault or a parallel structure, a close cousin of this fault,” he added.Tozzi said Wednesday’s ‘double-hit’ quake, in which an initial tremor of 5.5 magnitude was followed by one of 6.1, was typical of the central Appenine mountains.
