Magma Feeding the Eruption in Iceland Has a Complicated Past

The eruption at Sundhnúkur in Iceland has been going for over 10 months and we're starting to understand how the magmatic system feeding it works.

It has been over 10 months since the on-again, off-again eruption near Grindavík in Iceland began. Since then, multiple eruptions have tapped a source of magma at the base of the crust under the island nation. That magma made its way to the surface to eruption as spectacular lava fountains and flows that have covered a significant area of real estate near the small fishing village and Blue Lagoon hydrothermal area.

Thankfully, there has been only one death from a worker falling into a crack while two other people have been injured from inhaling sulfur dioxide gas and unauthorized hiking onto the lava fields at night. This is a testament to Iceland's ability to mitigate against any further harm through careful volcano monitoring.
