When Quiet Undersea Volcanoes Turn Disruptive
A recent expedition off the coast of Iceland has revealed unexpected volcanic activity beneath the ocean. Researchers discovered smooth mounds along the Reykjanes Ridge, challenging previous assumptions about the behavior of undersea volcanoes. These findings may also provide insights into historical accounts of islands that appeared and disappeared in the ocean.
- ▪The expedition was conducted by a team of scientists aboard the research vessel Meteor.
- ▪They discovered smooth mounds along the Reykjanes Ridge, contradicting the typical rough terrain expected from mid-ocean ridges.
- ▪The findings could be linked to historical accounts of mysterious islands that surfaced and then vanished.
