Phreatoplinian Eruption - John Seach

Phreatoplinian Eruptions are characterised by large wet eruptions. They are an order of magnitude larger than surtseyan eruptions. There are no modern examples of this type of eruption.
Mt Usu in Japan may have produced a Phreatoplinian eruption in April 2000 if the magma reached the Lake Toya.
