Yeah, the article is jumping in midstream here, this has been going on for a few weeks. So the locals pretty much know where they are talking about. The geothermal power plant supplies not only electrons to the grid, but all the hot water to local cities. That's how they heat their homes and use hot water. If this basaltic eruption (It will be similar to the recent three eruptions) happens near the plant and the blue lagoon, it will get weird for the residents. There is the possibility that Grindavik on the coast could be the best way for the lava to flow.

My contact in Grindavik says it has been pretty much like before the previous events. The local government has been very active in monitoring and preparing. There are a few live internet cameras trained on the area from high view points.

Reykjavik and the airport do not seem under concern. The GPS and seismic are all pointing to a magmatic horizontal sill growing about 4 klicks down, just southwest of the plant. It's trying to find a way up. Will it? Time will tell.
