intense strombolian eruptions continue with lava flows from flank vents
Ash emissions have increased and reached 5 km altitude in the southern direction.
Active lava flows continue to advance from both fissure vents and have been reaching 2800 and 2700 m elevation into the Valle del Leone.
The high level volcanic tremor has been fluctuating a lot during the past few days, currently located at 3 km altitude beneath the Southeast crater.

new fissure vent, two lava flows
Opening of the new vent, located to the northwest of the latest fissure, was accompanied by intermittent ash emissions and lava spattering that has changed to erupting small lava fountains and spilling a new lava flow out towards the northeast.
In parallel, the advancing lava flow from 12 May remains active traveling E-NE direction into the Valle del Bove.
Intense strombolian-type explosions continue from the Southeast crater with glowing ejecta of lapilli and lava bombs.
Preceded to the eruption, a typical sharp peak in tremor accompanied the event which continues at fluctuating intensity at high values.

small, but intense lava fountains feeding lava flow + stunning video footage of lava
Behavior of the volcano has changed over the last 24 hours and slowly, but surely intensified characterized by strombolian activity at the vent.
It appears (and judging from the live stream) that the vent started to produce pulsating small lava fountains likely caused by magma change composition from basaltic gas-poor to gas-rich melt.
Currently there are no signs to cease the eruption in the near future as indicate the high and stable volcanic tremor.

Ecco la colata di lava alimentata dalla bocca effusiva che si è aperta giovedì scorso sul fianco settentrionale del cratere di sud-est dell'#Etna. L'attività di questi giorni è molto scenografica e tranquilla e al momento non si sta intensificando.

strombolian explosions, outpouring lava flow continues
Strombolian activity at the Southeast crater has been mostly mild only, but at intense values has produced ash emissions.
The strong volcanic tremor has been located at about 3 km above sea level.
No significant ground deformation was detected.

smoothly flowing lava glows over Catania
The volcanic tremor has continued at stable conditions over the weekend and is still continuing. This likely suggests a delicate equilibrium of effusion rates of magma.
