Even if the present floor phenomena are weakening, the overall lower in eruptive job may well be deceptive: knowledge acquired from geophysical can not exclude that magma provide into the similar dike that fed the hot eruption remains to be in development, and may open its means with new fissures right down to altitudes underneath 2,400 m, particularly within the space of the southern and western partitions of Valle del Bove.
