The subterminal eruption marking the northeast crater of Etna,ongoing since July 5,  continues.

On 1 August, late morning, dilute ash emissions were noted at the outset of a point on the west side of the small cone that has formed around the vent of 25 July. This vent still produced an intense strombolian activity without significant changes and began to emit a small lava flow toward the Valle del Leone. (INGV)

The eruptive fissure, opened at the base of the cone northeast, progressing up on its side.

An excellent map was published by Giorgio Costa on his website

On August 3, loud explosions are heard and succeed at a high rate.

This type of subterminal activity took place in the past : in 1956, in February 1964, in the spring 1968, and between 1975 and 1977 in the area of ​​Pinta Lucia, for nine months in 1999 and recently in 2006 (Source: Giorgio Costa /  Etna il Vulcano)
