Overnight, lava eruption and flow have slowed down. Lava is flowing west and south, threatening the town of Hraun and the Suðurstrandarvegur road east of the barriers that protect Grindavík and is likely to reach the sea.
Two of the three roads (north and east) to Grindavík are closed. Land changes have caused some damage to Nesvegur, the road on the west.
Dotted with volcanoes, geysers and underground magma chambers, #Iceland is no stranger to earthquakes and lava eruptions.
Iceland lies on the divergent boundary between the Eurasian plate and the N. American plate. It also lies above a hotspot, the Iceland plume, which is believed to have caused the formation of Iceland itself, the island appeared over the ocean surface about 16 to 18 million years ago.
Here is an aerial view taken last night showing the town of Grindavík, the Blue Lagoon and power plant to its north and the encroaching lava flow towards its east.
There are lava barriers north and east of Grindavík; see post #1 for their locations.
