Oceania's Most Explosive Volcano You've Never Heard of

Описание: One of the most consistently highly explosive eruptive centers in all of Oceania is a volcano that few people have ever heard of. Located within New Zealand, most of this volcano's eruptions have reached at least a volcanic explosivity index of 4 during the last 10,000 years. I am not referring to Taupo, Ruapehu or Okataina. Instead, I am referring to an island volcano known as Raoul Island.
