A strong earthquake swarm is currently ongoing at Iceland's Eldey volcano, located just offshore of the southwestern Reykjanes Peninsula. This has involved more than 400 earthquakes, but is this volcanic or tectonic? Today's video will attempt to answer this question through the knowledge and analysis of a geologist.
