Volcano on Gibraltar

[Autanimous]

If in the early 1900's a volcano developed on the strait of Gibraltar, eventually sealing the Mediterranean by 1940 from that entrance...
What are the Effects?

Hundreds of geologists suffer heart attacks at the impossibility of it....

[Autanimous]

Why so?
The Azores-Gibraltar Fault runs through there, and while it is a diffuse boundary, a hot spot developing below there is no more unrealistic than the one under Hawaii...

[Faralis]

And also the small detail that a Volcano so big to close a 14 Km strip of about 300 meters of water would be a nightmare to the climate ...

The British are going to have a hell of a time reinforcing the Mediterrenean Fleet and their army units stationed there. They'll have to go round the Cape Of Good Hope and up the Suez Canal. If the Second World War proceeds the way it did IOTL, all the Axis need to do to acheive naval supremacy in that area would be to launch a massive air raid or commando attack to shut down the Suez Canal.

Just out of curiosity, how the hell will a volcano at Gibraltar seal the Gibraltar entrance to the Med?

With lava, ash, pumice and other debris. Lots of MAGMAAAAAA

Look up Surtsee, it's an island off the coast of Iceland that wasn't there when I was born 50 years ago.

Sice the rate of evaporation in the Med is higher than the flow of water from the rivers, closing the strait means that the Med begin slowly shrinking.
Countries with larger coastline (e.g. italy) are about to expand their territory.
Climate is becoming harsher (hotter summer, colder winters).

Short answer: Anything's possible.

Well, actually what would happen is:

Say hello to the "Gibraltar´s Canal" ... and thats all.

Well maybe the Brits impose military presence in Morocco to the Spanish, not sure but probably ...

Ah, sorry, you don't dig a canal through a still active volcano.

[Autanimous]

With such an important location, it's possible they would attempt to build a canal through an active volcano...
Whether they succeed or not IDK.

[Lord Grattan]

This really needs to be moved to the ASB forum.

Or they could just go around the volcano. That would make the canal longer and more expensive to build and maintain, but it bypasses the issues of working too close to an active volcano.

This ... what is a pair of million of Pounds if you can arrive to Alexandria in time to good cup of Tea

In the ASB forum. Not here.
That's why we HAVE an ASB forum.....

[Autanimous]

This doesn't seem that ASB though.

It's a very realistic possibility that the magma under the earth could have developed hot spots nearly anywhere. It's no more ASB than a hurricane being stronger or hitting a different spot, it just has a much larger effect.

At least 1/3 of the Planet's population dies, maybe as much as 3/4.

This is Tambor, but on a continuing basis for decades. This could easily bring about a new Ice Age due to the lack of sunlight getting to the surface. Kiss off Canada, Northern France, Germany, Japan from Honshu north, Korea, Manchuria, New Zealand, Russia, Scandinavia, the UK, and the northern 1/3 of the United States.

Expect Sea Level to drop by between 5 & 10 feet by 1940 due to glacial build-up.

At least there won't be any World Wars.


BTW: Faults do not always equal volcanoes.

As I said earlier, the example would be Surtsee. Those massive effects are from already established volcanoes going bang. Getting a Surtsee style volcano in the Straits would block them over a period of time and wouldn't necessarily put huge amounts of gunk into the atmosphere.

The one currently playing around in Iceland is creating the problems that it is because of the ice and snow coverage on the surface, take that away and you don't get the ash cloud.
