general question on supervolcanoes

does anyone know which volcano when erupted could cause a world wide dust/smoke matter across the globe?, i know these have happened before long times ago but i am just curious and could not find the info i was looking for.

Explanation:

Lake Toba [wiki]

Toba Catastrophe theory [wiki]

Mount Tambora [wiki]

Year without a Summer. [wiki]

Personal Disclosure: I hope that helps shed some light on the issue for you!

Edited spelling fail. :shk:

hey thanks just what I was looking for!

Toba was the largest erupted supervolcano that was ever recorded in history. But I have my eyes on Yellowstone, that supervolcano, not only that it will create a global blanket of ash, but I live about 500 miles away from it, just along the border of the danger zone.

It's caldra measures 55 by 72 kilometers, and who knows how many kms of depth it has. But has a very large pocket sitting there. If this thing erupts, it'll be the loudest explosion that you've ever heard, any sound over 200 decibels can kill ya. I estimate the amount of ash could perhaps cover the entire U.S with a few inches of it.

I could imagine that all supervolcanos can cause widespread ash in our atmosphere. For how long? Months to a few years. Depends on how much gets kicked up.

Awh damn I was too slow :p

I have always been interested in archaeological rocks formations etc, but the pure beauty of volcanoes is unreal, I mean also diamonds and other precious crystals are formed inside these shafts.
Too many people think that they are a bad thing but these are my good lists...

Pure beauty.

brings new life after eruption.

new creatures inhibit these new untouched lands.

new breeds of plants and wildlife are formed.

Beautiful gems formed from carbon.

I could go on but i would love to visit one of these lands after it has obviously regrown.

even spice traders have risked their lives just to get a handful of amazing spices from other sides of the world... must be special.
