Lava piling up at the berm north of Grindavik:

Reykjanes volcano 16 Mar 2024

The dark material on the ground is the cooling lava from the eruption that was the one before the prior one.

You can see the greenhouse in the middle of the image, with lava on its north side. It was protected by a small berm.

You can also see the small fissure on the side of Grindavik that pour out lava that burned three houses in the town.

The berms now are high enough supposedly to keep the new lava from breeching them. We’ll see.
