You cannot be a super villain if you don't have a secret lair inside a volcano.

Preferably one with a cauldron of bubbling lava you can slowly lower 007 into once you

finish monologuing at her and leave the room laughing maniacally, confident in her impending

But it turns out that volcanoes with active lava lakes are incredibly rare.

Of the roughly 1,500 active volcanoes worldwide, we only knew of seven with lakes of bubbling

Until July of 2019, when scientists announced they had found an eighth, and it is the most

It's called Mount Michael, and it's located on one of the South Sandwich Islands about

The mountain is mostly covered in glacial ice, perfect for covering in guard wolves

No one has ever summited Mount Michael on account of stratovolcano's steep sides.

If no one's ever been to the top of the volcano to peer in, you may be wondering how

we know Mount Michael has one of the world's few lava lakes.

It was only discovered thanks to decades of satellite imagery.

Thermal anomalies were first spotted in the 1990s and again in the early 2000s, but the

image quality and processing techniques weren't advanced enough to prove there was a lava

But from 2003 to 2018, multiple missions collected better data allowing researchers to conclude

that Mt. Michael was home to a lake of lava about 70 to 150 meters across, and potentially

This volcano is pretty remote, so it doesn't pose much danger to anyone,

But studying it may help us predict the hazards posed by other lava lakes, some of which are

One such volcano is Kilauea on the big island of Hawai'i, and its lava lake contributed

to serious destruction as recently as 2018.

In late April of that year, it spilled out from the summit, then a few days later the

lake began to drain as magma moved downslope underground.

Eventually the magma broke through the surface, and by early June over 20 fissures had opened

This continued for months, destroying over 700 homes, displacing thousands of people,

and blanketing over 35 square kilometers of land in lava.

When volcanoes erupt, it's not the tsunami of fire you might imagine and sometimes it's

possible to outrun or even outwalk the molten rock.

When volcanoes do kill it's likely the avalanches of rock and ash called pyroclastic flows,

or mudflows called lahars that will get you.

But another volcano that's home to a lava lake has killed with superfast lava.

Mount Nyiragongo in the Democratic Republic of the Congo is a steep-sided stratovolcano,

periodically containing a lake of particularly low-viscosity lava that's currently about

In 1977, the crater wall holding the lava lake inside broke, sending lava traveling

as fast as 100 kph barreling down the slopes, destroying nearby villages and taking lives

So any new lava lake we discover offers a chance for further study and clues on how

We still don't know why some of them persist, it could be the lakes are connected to a cache

of magma deep underground, or the gases coming up from underneath are hot enough to keep

It would help if we could find more of them to study.

Some scientists have suggested that we might have luck discovering them beneath the oceans,

where the majority of the world's volcanism occurs.

If we can only find these 8 lava lakes on the surface, maybe diving under the waves

will be our next step to study this rare phenomenon.

Supervillains may be trying to destroy the world, but every-day villains are trying to

steal your identity, and there's way more of those guys.
