A glaciovolcano is a volcano covered by glaciers. When it erupts, the glaciers covering it can melt. What is the most likely result of such an eruption? Group of answer choices

a flood

an avalanche

a tsunami

an earthquake

a flood

Explanation:

a flood – this is the right answer. As the eruption happens below the surface of the glaciers, the ice on the top melts under the erupting lava. This melted ice turns into the water, causing the flooding. These floods are called Jökulhlaups, meaning “glacial run” in the Icelandic language as it is in this country that glaciovolcano eruptions can often happen. This is the type of glacial outburst flood, and the most famous example is the eruption of Grímsvötn volcano in 1996.

an avalanche – this is not the right answer. There are glaciers and ice on the glaciovolcano, and it is snow that creates an avalanche. Also, the snow would be melted under the health.

a tsunami - this is not the right answer. The eruption of glaciovolcano can’t cause the tsunami.

an earthquake – this is not the right answer. Glaciovolcano eruption doesn’t cause an earthquake.
