Description
Morphology
It is a small, non-continuous fissure, with a total length of 36 metres and a maximum height difference of 6.70 metres; this fissure is related to the Amer fault, in fact it is located on a fault line. We also find, parallel to and below the main fissure, some small fissures that are completely impenetrable.
History
A cavity that is not documented speleologically, known to geologists and hikers.
It is related to the earthquakes that occurred in 1427, where according to the chronicles of the time various fumaroles of toxic gases appeared at different points on the mountain, causing deaths.
From the well-verified primary historical sources, no descriptions have been cited of ground ruptures with displacements of both lips, that is, fault scarps related to the 1427 seismic events; only open fissures with subvolcanic emanations between Lloret Salvatge and Amer during the earthquake of 22-04-1427.
