Iceland’s Reykjavik volcano has erupted for the fourth time since December, the Icelandic Meteorological Agency said, spewing fiery lava into the air.

Icelandic authorities have been warning for weeks that the volcano south of the capital Reykjavik is about to erupt.

It is the volcano’s seventh eruption since 2021.

Its last eruption was in early February, when lava destroyed roads and pipelines, leaving 20,000 people without heating. In the January eruption, lava burned houses in a fishing town.

Between the Eurasian and North American tectonic plates, Iceland is a seismic and volcanic terrain due to the movement of the two plates in opposite directions.

Volcanic eruptions in the Reykjanes Peninsula are usually of limited dimensions and do not cause large dispersion of ash into the stratosphere.

But scientists worry they are likely to continue for decades, and Icelandic authorities have begun building dikes to divert the flow of burning lava away from homes and infrastructure.

Iceland is home to more than 30 active volcanoes. In 2010, ash clouds from the eruptions of the Eyafjallajokull volcano covered large areas of Europe, canceling 100,000 flights and forcing hundreds of Icelanders from their homes.
