Almost without warning or significant preceding activity, a paroxysm - a short-lived, but intense lava fountaining eruption - took place at the New SE crater during the early hours today.
Shortly after midnight, volcanic tremor amplitude rose sharply to very high levels and a lava flow started to descend from the cone towards the SW into the upper Valle del Bove, as the magma column inside its conduit was being pushed up by a batch of gas-rich fresh magma.
Shortly after, strombolian activity began from the cone's summit crater as well, and quickly merged into moderate lava fountains. Shortly before the eruption, volcanologists could record a rapid inflation by about 1 microradiant of the volcanic edifice. By about 6 am in the morning, the eruption had ceased.
