Five Magma Intrusions, Three Eruptions

Five magma intrusions have formed near the town of Grindavík, Southwest Iceland, since November but only three of them have broken the surface as eruptions. Magma continues to collect below Svartsengi and uplift (land rise) continues at the site. Recent earthquakes on Reykjanes are more likely a result of magma cooling underground than signs of an impending eruption, according to Salóme Jórunn Bernharðsdóttir, natural hazard specialist at the Icelandic Met Office.

Three brief eruptions occurred on the Reykjanes peninsula near the town of Grindavík in December, January, and February. In late February, as the magma chamber below Svartsengi filled once more, experts predicted a fourth eruption would occur in early March. However, while collecting magma flowed out of the chamber, it never broke the surface and now appears to be cooling underground.

Magma continues to collect below Svartsengi and the amount is now more than it was before the magma intrusion in early March. Salóme told RÚV that if another eruption occurs at the site, it will likely be preceded by the same seismic activity as the last three eruptions in the area.

The eruptions have not impacted flights or travel to and from Iceland.
