Portugal Colonial - Iceland's volcanic eruption slows as lava flows from second fissure

After weeks of warnings, the Icelandic Meteorological Office (IMO) said Thursday that a new eruption had started at 9:26 pm (2126 GMT) that evening, following a series of earthquakes.

Video images showed orange lava bursting out of a long fissure, which the IMO estimated to be 3.9 kilometres (2.4 miles).

Early Friday, the IMO announced on social media that a second fissure had opened up to the north of the original one.

In an later update, the agency said that "the intensity of the eruption has decreased significantly since yesterday."

It added that the "most active fissure is the one which opened during the night."

This is the sixth eruption to hit the area since December, coming just two months after the end of a previous eruption that lasted more than three weeks.

The latest eruption occurred north of previous eruptions and since no lava flowed south it posed less of a risk to the nearby fishing village of Grindavik, which was evacuated Thursday evening.

The chief of police of the Sudurnes region, Ulfar Ludviksson, told Icelandic media that the 22 or 23 houses in the village were currently occupied.

Most of Grindavik's 4,000 residents had evacuated in November, prior to a December eruption, and while residents have since been allowed to return in between eruptions, only a few have opted to stay overnight.

The IMO also noted that there would be "northerly and northwesterly winds at the eruption site" until Saturday, which therefore would spread gas pollution from the site south and southeast -- carrying it out to sea.

Further eruptions occurred in August 2022 and in July and December 2023, leading volcanologists to warn that a new era of seismic activity had begun in the region.

Iceland is home to 33 active volcano systems, the highest number in Europe.

It straddles the Mid-Atlantic Ridge, a crack in the ocean floor separating the Eurasian and North American tectonic plates.
