New Eruption Likely This Weekend

A new volcanic eruption could happen this weekend, according to Ármann Höskuldsson, volcanologist with the University of Iceland. The most likely place for it would be Sundhnúkagígar, where eruptions took place in December, January and February, damaging the nearby town of Grindavík.

Last night, the Icelandic Meteorological Office reported some sixty earthquakes over a 24 hour span in the magma corridor that lies under the area. The area with the highest level of activity was to the east of Sýlingarfell, where the first signs of a magma intrusion are expected to come to light.

Eruptions in Eldvörp possible

In an interview with Mbl.is, Ármann said that there’s no reason to think that a new eruption won’t occur in the area in the coming days. “Except if it were to occur in Eldvörp,” Ármann said.

Eldvörp is a row of craters to the northwest of Grindavík, the town of 4,000 inhabitants that was evacuated during the series of seismic activity and eruptions since November. Ármann explained that nearby Svartsengi, home to a geothermal plant and popular tourist destination Blue Lagoon, is something of a trap for magma, which is why it’s become the centre of activity.

Were the magma to reach Eldvörp, the activity around Svartsengi will cool off, as Eldvörp provides an easier route for the magma to reach the surface, due to its location on the boundaries of the Eurasian and North American tectonic plates. Ármann added that persistent seismic activity was the only way for the magma to break through to Eldvörp, with each volcanic eruption making it more likely.
