Etna (Sicily, Italy): Volcanic Ash Advisory Center Toulouse (VAAC) issued the following report: ERUPTION AT 20210307/0624Z STRONG STROMBOLIAN ACTIVITY
…7 Mar:
The 10th paroxysm of Etna’s New SE crater is well underway: Impressive lava fountains have begun to shoot into the sky from the New SE crater a short time ago, while a tall dark eruption column of volcanic fragments and gas rises several kilometers.
Westerly winds are pushing the eruption cloud eastwards, strong ash and lapilli fall is likely occurring in the villages and towns of Etna’s eastern flank including Zafferana, Milo, Giarre…
Aviation Color Code has been raised to „RED“.
…7 Mar:
After 3 days of relative calm since the last lava fountaining episode known as paroxysm at the volcano’s New SE crater, a new one seems to be underway now at the crater:
Accompanied by the typical steep rise of volcanic tremor, indicating magma moving upwards through the volcanic conduits, strombolian activity has been picking up at the summit vent of the New SE crater during the past hours, and now seems to be heading towards lava fountaining. Also, another typical sign for the impending paroxysm, a lava flow is issuing from the eruptive fissure cutting through the cone and flowing towards the eastern base of it. This is likely the mostly degassed older lava from the previous paroxysm left in the upper part of the conduit being pushed out by the rising fresher, and gas-rich magma about to erupt.
This marks the 10th paroxysm in a row in a remarkable series since 16 February. Intervals between individual eruptions have been very regular, ranging between 36 hours to 3.5 days only, and there are no signs that it this series is ending soon.
Fagradalsfjall (Reykjanes Peninsula, Iceland): (7 Mar) The situation remains tense. A large magnitude 5.0 quake occurred last night at 02:02 about 3 km WSW of Fagradalsfjall. IMO reported that additionally, from midnight over 30 earthquakes over M3 and 5 larger than M4 have also been recorded.
Another pulse of tremor was recorded that lasted for 20 minutes. Its intensity was similar to the one measured on the e March, however that tremor had lasted several hours.
…7 Mar:
For more than a week now, Iceland’s Reykjanes Peninsula has been continuously rocked by an intense earthquake swarm: A total of more than 20,000 tremors have been recorded since the activity started on the Reykjanes Peninsula on 24 February 24 when a magnitude 5.7 quake occurred, followed almost immediately by a magnitude 5.0 event.
In total, the Icelandic Meteorological Office (IMO) recorded 5 quakes of magnitude 5.0 or above, 51 quakes between 4.0 and 5.0 and 397 quakes between 3.0 and 4.0. Many of these quakes were felt in nearby villages and towns, but luckily, the immediate areas around the earthquake swarm are not densely inhabited and there have been no reports of significant damage.
