Seismic activity indicates low threat level for Grindavík amid eruption on Reykjanes Peninsula

Seismic activity continues on the Reykjanes Peninsula, with reports suggesting a more favorable eruption location compared to the previous event. Magnús Tumi Guðmundsson, a geophysicist, noted that this eruption features the longest fissure recorded at approximately four kilometers. Notably, there are few signs of activity in the southern part of the fissure, which is promising.

“Given how things stand now, there is no lava flow threatening Grindavík,” he stated, adding that the situation should be closely monitored as the eruption is still in its early stages. During a recent aerial survey, which showed manageable conditions, Guðmundsson emphasized the importance of vigilance but indicated that the current location is less concerning than before.

He described the lava flow rate as nearly two kilometers per hour, directed northwest toward Grindavík road. However, Guðmundsson reassured that, while future developments could alter the landscape, the potential for danger to key infrastructure remains low at present.

He expressed that for the flow to pose a threat northward, it would need to behave differently than previous eruptions. Early stages of similar events typically feature vigorous lava flows, which tend to decrease in strength over time.

Guðmundsson concluded cautiously, stating that although it is premature to declare the threat level, current conditions suggest that Grindavík is not in immediate danger.
