Lava Could Reach Reykjanes Roadway If It Rises Any Higher

It’s possible that lava from the ongoing eruption in Meradalir could flow eastward in the next 24 hours, RÚV reports. Professor of Geophysics Magnús Tumi Guðmundsson says that if this were to happen, the lava would have a direct path to Rte. 427. Also called Suðurstrandavegur, this road runs along the south coast of the Reykjanes peninsula between the municipalities of Grindavík and Ölfus.

Magnús Tumi notes that the lava hasn’t yet started flowing out of Meradalir. “However, in the last two days, the lava by the mountain pass, which is the lowest point out of the valley to the east, has risen seven to eight metres [23-26 feet]. And it will only take maybe a metre or so for it to overflow. So if the situation continues like this, the lava will overflow the valley soon.”

It’s difficult to say if the lava would actually reach Suðurstrandavegur, says Magnús Tumi. “But in order to be able to estimate any sort of timeline, it’s vital that we be able to take new measurements of the lava volume and thereby the flow.” Unfortunately, ongoing weather conditions since Thursday have prevented scientists from taking these critical measurements.
