Map of today’s active volcanoes

Etna (Sicily, Italy): (28 Oct) The volcano has been relatively calm, at least at the surface, during the past weeks.
However, there are clear signs that Etna is not in a deep slumber and might wake up with a more vigorous phase of eruptions at any time. The most telling is in the form of occasional, mild strombolian explosions from the SE crater such as observed last night, indicating that magma inside the conduits remains high.

In many cases, such activity has been prelude for violent lava-fountaining episodes known as paroxysms, such as last in August this year. The onset of these is usually characterized by increasing strombolian activity along with a rise in volcanic tremor, first increasing gradually over hours or days, then very sharply during few minutes until reaching impressive peaks of violent activity.

Brennisteinsfjöll (Reykjanes Peninsula, SW Iceland): The latest GPS and InSAR (Interferometric Synthetic Aperture Radar) statistics detected an area around Svartsengi inflated. The uplift commenced some time on 27 October, indicating a propagation of magma through intrusion/s.
The center of the bulged ground surface is located about 1.5 km to the northwest of Þorbjörn, close to the popular Blue Lagoon.

In 2020 and 2022, uplift detections were monitored in the same area with comparable geometry. This uplift is now 5th inflation in row in the area over the past three years. Furthermore, a significant rock fracturing has took place in the Svartsengi area recently due to the increased ongoing seismic energy. This might create a potential pathway for magma allowing it to rise further to shallower depths.
At the moment, there is no likelihood of magma movements towards shallower levels.

…28 Oct:
Over the past 24 hours, the seismic swarm has been decreasing in intensity. It might be a sign that the possible magma intrusion is weakening, and that the likelihood of a new eruption decreases, at least for now.
