Guest Video: Vanuatu’s Volatile Volcanoes

A submarine volcano at Vanuatu’s Epi Island made news recently, but it is only one of many local fire mountains that keep experts and laypeople here on their toes (scroll down to volcanoes).

What is Vanuatu and why does it have so many active volcanoes and earthquakes?

As near as I can tell from a quick look-up, it is an archipelago that has formed in a subduction zone between the Pacific and Australian tectonic plates — with some complications (to this layperson, anyway).

Wikipedia and Volcano Discovery are good places to start exploring these questions.
