The volcanoes of Iceland include a high concentration of active ones due to Iceland's location on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and its location over a hot spot.

The island has around 30 active volcanic systems, comprising each volcano-tectonic fissure systems and many of them also a central volcano (mostly in the form of a stratovolcano, sometimes of a shield volcano with a magma chamber underneath). Thirteen volcanic systems have hosted eruptions since the settlement of Iceland in AD 874.

Of these 30 active volcanic systems, the most active is Grímsvötn. Over the past 500 years, Iceland's volcanoes have produced a third of the total global lava output.

With over 20,000 earthquakes hitting Iceland within days of recording, Jake Mammal and Oliver Cuttle discuss the global implications and how best to survive the collapse of society and Earth as we know it. A few other topics are discussed, but that's for you to discover.
