Q

What were the primary effects of this eruption?

A

Heat from the eruption melted vast amounts of ice under the ice cap. Meltwater subsequently emerged as a glacial burst leading to flooding.
Ash mixed with meltwater and rain created lahars. This lead to mudslides and it fell into rivers increasing flood risks
