Only two miles from shore … and no one even knew they were there.
The previously undiscovered volcanoes lie just three km (2 miles) from the Gulf of Naples, home to Mt Vesuvius, and the most densely populated volcanic region in the world. Some three million people live in the city of Naples.
When Mt. Vesuvius erupted in 79 AD, it killed all 11,000 inhabits of Pompeii, making it one of the deadliest eruptions in human history.
Researchers discovered the new volcanoes in 2014 while garnering more information on Vesuvius, which is overdue an eruption.
“We detected new points of carbon dioxide emissions in the Gulf of Naples, which is quite common in geothermal and volcanic areas such as Naples,” said Guido Ventura, of the National Institute of Geophysics and Volcanology (INGV.

“Notice how close these were to the shore and still undiscovered until very recently,” says George. “As you say there must be many millions more undiscovered submarine volcanoes.”
