Canberra, Australia - Dozens of newly discovered volcanoes in a stretch of the Pacific Ocean pose a major tsunami risk due to the area's seismic instability, an Australian geologist warned on Thursday.
Research teams from the United States, Germany, Australia and New Zealand have discovered 75 previously unknown volcanoes in a 2 000km strip from New Zealand north to Tonga in the past six years, Australian National University geologist Professor Richard Arculus said.
Previously, only 10 volcanoes were know to exist in the 20 000km² of seabed.
"It's far more active than previously thought," Arculus said. "It's as active as anywhere else on the planet."
Asked if the strip of volcanoes posed a major tsunami risk, he said, "Personally, I think it does."
