The range, after running nearly north and south, terminates at Padula, after having made an abrupt bend to the westward in the above azimuth (by compass) from the Certosa. Hence it is to be inferred that the transverse shock (the first in point of time) was delivered from the free extremity of the range of limestone mountain, along the axis of which it had followed, while the great primary or direct shock (the second in point of time) came normally through the clays, gravels, and other formations, beneath and in, the Vallone di Diano, both intersecting at the Certosa.
