Researchers have discovered a new, small volcano in the Pacific Ocean off Japan.
The team from Japan’s Tohoku University found the volcano in the western part of the Pacific Ocean near Minamitorishima Island. The volcano is known as a “petit-spot” volcano on account of its small size.
“Petit-spot volcanoes are a relatively new phenomenon on Earth,” said Tohoku University in a statement. “They are young, small volcanoes that come about along fissures from the base of tectonic plates. As the tectonic plates sink deeper into the Earth's upper mantle, fissures occur where the plate begins to bend causing small volcanoes to erupt.”
Experts think that the volcano erupted less than 3 million years ago. Petit-spot volcanoes were first discovered in 2006 near the Japan Trench, to the northeast of Japan.
"The discovery of this new Volcano provides an exciting opportunity for us to explore this area further, and hopefully reveal further petit-spot volcano," said Naoto Hirano, an associate professor at Tohoku University, in the statement.
The research is published in the journal Deep-Sea Research Part I.
