From 25 to 29 August 2010, numerous explosions, internal collapse, and
ash emissions have occurred at the Bocca Nuova, the westernmost of the
four summit craters of Etna.
In contrast, all ash emitted by the
events of the following days is lithic, and no emission of hot material
(pyroclastic or gas) has been recorded by the thermal surveillance
camera on the Montagnola.
There has been no evident change in
the activity of the other summit craters; deep explosions within the
active pit of the Northeast Crater have been occurring continuously
since several months.
