Santorini volcano update: Media speculate about potential volcanic eruption
More than 7700 earthquake registered in about 9 days at Santorini
More and more news articles published in Greek media seem to suggest that the seismic crisis is more likely than not to lead towards a new volcanic eruption at Santorini, or (more likely probably) at the submarine Kolumbo volcano. For example: «Η έκρηξη του ηφαιστείου στη Σαντορίνη θα γίνει» (tanea.gr, translated: „The eruption of Santorini’s volcano will come“)
This needs to be taken carefully – it is well known that many outlets tend to sensationalize news, unfortunately. The available data about the situation so far do NOT conclude that at the current state, a volcanic eruption, while not impossible, might be a very likely scenario. A magmatic involvement cannot be ruled out, but this does not mean necessarily that an eruption will follow.
Santorini volcano update: Another magnitude 5.1 quake hits Santorini
Location of recent M4+ quakes near Kolumbo volcano NE of Santorini island
Earthquakes continue with little signs of slowing down. Another strong mag. 5.1 quake hit Santorini about an hour ago 22 km northeast of the island and was felt widely.

Italy’s volcano and earthquake monitoring agency INGV, one of the world’s most renowned, published an interesting article about the recent seismic activity on Santorini and the tectonic setting of the area.

Stromboli volcano (Eolian Islands, Italy): new lava overflow on Sciara del Fuoco, which stopped in meantime

The National Institute of Geophysics and Volcanology (INGV) reported that a new effusive eruption commenced at the volcano yesterday.
At about 06:08 local time, a new lava started to ooze out from the North Crater area following an intense spattering over the past few days. The lava had been travelling beyond the crater further onto the upper Sciara del Fuoco.
Ordinary strombolian explosions had continued from both North and Central-South crater areas.
The volcanic tremor reached its peak and preceded the lava flow formation, which in turn, returned back to medium values.
Meanwhile, the lava flow from the North Crater area ceased some time yesterday and is now no longer active while cooling.
