Eruptions at Sinabung, Sabancaya, Etna and Lengai.

After a two-week increase in sulfur dioxide emissions, based on the Aura OMI satellite detections, a sign of a rise in fresh magma, and seismicity since February 17, the Sinabung presented this February 19 at 8:53 am WIB a strong eruption; It was accompanied by a plume of ash and gas rising to 5,000 meters in height, and several pyroclastic flows traveling 4,900 meters to the SSE and 3,500 meters to the ESA, lasting between 195 and 792 seconds. ; They have only impacted areas banned by the PVMBG, in principle not making victims.

This eruption left an important and long seismic signature.

The Observatory upgraded the VONA / aviation warning code to red.

In Peru, heavy rains in the Arequipa region, which could remobilize the ashes of the Sabancaya eruptions, triggered an alert to the lahars in the quebradas near the volcano.

Small episodes were recorded during the past week, lasting more than an hour, without problems.

On Etna, the "puttusiddu" vent has continued to emit small ash emissions since February 16, at an accelerated frequency of 1 to 2 episodes per hour; these emissions also include the ejection of incandescent fragments.
