Ambrym Island Volcano
- Estimated Date: 50 BCE
- Location: Republic of Vanuatu
- VEI Rating: 6
In the southwest territory of the Pacific Ocean, you’ll find several small islands. Around this territory, you’ll find Ambrym Island which happens to be part of the Republic of Vanuatu. This happens to be the site of a major eruption that took place in 50 BCE. While volcanic eruptions can be powerful, very few are able to create a caldera on an island that is 7.5 miles wide. Upon erupting, volcanic ash and debris were sent for thousands of miles. The eruption, to the shock of no one, was rated a 6 under the Volcanic Explosivity Index. What might freak you out more is that this very same basaltic volcano is still active to this day!
Today, everyone knows Ambrym Island as simply a volcanic island that now includes two different lava lakes. The two crater lakes actually happen to be the site of two volcanic cones known as Benbow and Marum. We’ve seen many Ambrym volcano eruptions that were quite destructive. While the eruption that took place in 50 BCE was huge, Mount Benbow actually erupted in 1913 too. When it did, it completely destroyed a nearby mission hospital. Gas emissions from the volcano have found it to be active, meaning Ambrym Island could see future eruptions at any time!
