Waning Volcanic Activity Hints at End of Reykjanes Eruption

Volcanic activity on the Reykjanes peninsula is waning, suggesting the current eruption may conclude soon. A volcanologist anticipates more eruptions in the area, predicting a cyclical pattern of intense but brief activity, potentially altering if magma gathers in the Eldvörp craters.

More eruptions likely to follow

In an interview with a radio programme on the National Broadcaster this morning, volcanologist Ármann Höskuldsson stated that volcanic activity on the Reykjanes peninsula was slowly decreasing; the eruption could end as soon as tomorrow or the day after.

The northern crater of the fissure continued to spew lava westward, while lava from the southern crater was flowing out onto the plain. Ármann noted that eruptions in the area could not become any larger while issuing from the fissure near Sundhnúkar. Future eruptions are expected to be powerful but short-lived.

According to Ármann, it is likely that the current pattern of eruptions in the area will continue: a short eruption would occur, it would end, magma would begin accumulating again, and another eruption would occur. In the event that magma would begin accumulating in Eldvörp — a series of craters approximately ten kilometres long, where lava flowed during the Reykjanes Fires between 1210 and 1240 — this pattern would, however, likely change; the eruptions would become larger and last longer.

The current eruption is the third volcanic eruption to occur on the Reykjanes peninsula since December 18. The two previous eruptions have been relatively short-lived.

No lava fountains visible

In an interview with Vísir this morning, Sigríður Magnea Óskarsdóttir, a natural hazard specialist at the Icelandic Meteorological Office, stated that the MET Office had not observed any lava-fountain activity since between 8 and 9 this morning.

“That does not mean that the eruption is completely over; there could still be some bubbling inside the craters. Ideally, we would need to fly over the area to verify. The geological unrest has, however, completely calmed down, and there is little or no seismic activity. So, it is very likely that the situation will fully settle down shortly,” Sigríður observed.
