And we didn’t even know it!
Researchers studying the Monowai volcano near Tonga recorded huge changes in height in just two weeks. This latest analysis compared images gathered on May 14 and then June 1-2 last year and even in that short period the volcano had undergone a transformation.
The team found that one volcano, named Monowai, changed dramatically over just a two week time span, collapsing in one part and adding almost 80 meters of height in another. The team has described their findings in a paper published in the journal Nature Geoscience.
“The researchers believe the changes are larger than at most other volcanoes. Only Vesuvius and Mount St Helens have recorded larger growth rates.”
Bigger than Mount Vesuvius! That’s the huge volcano that buried Pompeii, and no one
even knew that it had erupted! And we wonder what has been heating the seas?
“A wake-up call that the sea-floor may be more dynamic than we previously thought,” says lead author Tony Watts of Oxford University. “I’ve spent my career studying the seabed and have generally thought it pretty stable so it’s stunning to see so much change in such a short space of time.”
As many as 32,000 underwater mountains have beenidentified around the world and the majority are believed to be volcanic in origin,” says this article by David Shukman. ” Several thousand of these
may be active but a combination of ocean depth and remoteness means that very few have been studied.”
“Several thousand of these may be active . . . and we wonder what has been heaqting the seas.
