After an increase in seismic activity in November prompted evacuations to entire towns in the Reykjanes Peninsula of Iceland, the volcano finally started erupting on Monday, December 18th. The first eruption began at 10:17 PM local time on Monday, December 18th between Sýlingarfell and Hagafell. According to the Icelandic Met Office, the eruption is expected to weaken and aerial images have shown that the previous five vents are now down to three vents, erupting just southeast of the town of Stora-Skogfell.
Since this eruption began, there were about 320 earthquakes that were detected, the largest earthquake was a magnitude 4.1 which happened around 11:25 PM locally on Monday.
According to the RUV, a Level of Emergency has been declared by Civil Defense. There is no immediate threat of lava flow to the town of Grindavik and volcanic gas is drifting eastward over uninhabited areas and out to sea.
