What would the climate effects of a Supervolcano be?
By admin
I am doing a research project on Supervolcanoes and their climate effects. If I were to (hypethetically) say that The supervolcano under Yellowstone National Park were to erupt, I know that the surfuric acid cloud would kill everything within between 250-700miles, create a nuclear winter, result in lower temperatures by 10-15C, and destroy our ecosystems.
How long would it take before the ecosystems were able to recovery, and how long would (the remainder) of humans be forced to survive with limited vegetation? And how long would the nuclear winter last? (I have heard people state between 4-5years, up to 10-12 years?)
Thanks for any possible assistance. 
check the discovery or history channel….there was a program on or will be on about supervolcanos….
the last time yellowstone blew it took the earth about 10000 yers to recover fully.
Try researching http://www.livescience.com/forcesofnature/050308_super_volcano.html. Very interesting and informative.
wow!!jus de kind of question i was lookin for….yes after it erupts and destroyes the whole country its not gona stop..de eruption den will give its”tata” or “see ya in few centuries”….de ice age will begin….and it can last for thousands of years!!
There are super volcanoes in Indonesia, the United States, Italy, & New Zealand. The impact on our climate could send us into another ice age and could kill millions of people. It could make existing food unfit to eat and make it impossible to to grow any food at all. They have the potiential to wipe out the human race or at least as we know it today.It could take 100′s of years to recover.
