The small strombolian activity that marked the southeastern crater of Mount Etna for several weeks suddenly increased yesterday February 27 at around 6 pm UTC.
The explosions of the vent in the saddle between the old and the new southeast cone became stronger and closer; they fed a lava flow that descends the south-eastern flank of a new small cone.
The tremor, after an abrupt rise, has stabilized.
The flow then saw its flow lower.

At Piton de La Fournaise, the volcanic tremor stopped around 10:10 local time on February 27, 2017. At midday, the projections stopped to leave place to an active plume of light color.
After nine hours of persistent residual degassing, the eruption stopped at 19:30.
However, the terminal cone inflation continues at both the top and bottom levels (recharge of the superficial magma chamber), and carbon dioxide concentrations in the soil at the heel remain high.
