Yesterday (20-October-2017) a strong earthquake swarm happened in south Iceland on the SISZ fault zone. This earthquake swarm is currently ongoing and stronger earthquakes cannot be ruled out at this point.
Largest earthquake that has happened so far had the magnitude of 4,1 and four magnitude 2,9 earthquakes have happened at the writing of this article. During the strongest earthquake yesterday some minor damage has been reported, items falling out of shelves and breaking, picture frames getting skewed on walls. For a short time the village of Stokkseyri lost all line phone communication, I don’t know how long that outage lasted but phone service was restored quickly according to the news on Rúv. Largest earthquake was felt over a wide area, all the way to Reykjavík and up to Akranes village and east to Hella village.
I don’t know if this earthquake activity signals a new period of earthquake swarm in SISZ. I have listed large history of earthquakes of the SISZ in a article from 2011 here.
Donations help me running this website properly and keep everything going properly. Donations also help me to buy food and pay the bills so I can write more articles about earthquakes in Iceland and future eruptions that are going to happen in Iceland. Thanks for the support. 🙂
