Did anybody watch the BBC documentary Super Volcano? Its about Yellowstone National Park actually being a super volcano that's ripe for eruption. Little did I know that there's actually a bigger super volcano right here in Asia! What's more disturbing is that it sits near the fault lines from the recent earthquakes!
The impact of it erupting is something like this:
"Magma would be flung 50 kilometres into the atmosphere. Within a thousand kilometres virtually all life would be killed by falling ash, lava flows and the sheer explosive force of the eruption. One thousand cubic kilometres of lava would pour out of the volcano, enough to coat the whole of the USA with a layer 5 inches thick. The explosion would be the loudest noise heard by man for 75,000 years."

As Indonesians struggled to recover from the second deadly earthquake to strike them in three months, an Australian expert warned on Friday that the country faces the prospect of a "super volcano" eruption that would dwarf all previous catastrophes.
Prof Ray Cas of Monash University's School of Geosciences said the world's biggest super volcano is Lake Toba, on Indonesia's island of Sumatra, site of both the recent massive earthquakes.
Cas told Australian media on Friday that Toba sits on a fault line running down the middle of Sumatra -- just where some seismologists say a third earthquake might strike following the nine-magnitude quake on December 26 and Monday's 8,7-magnitude temblor.
Those quakes occurred along fault lines running just off Sumatra's west coast and created seismological stresses that could hasten an eruption.
Cas said Toba last erupted 73 000 years ago in an event so massive that it altered the entire world's climate.
"The eruption released 1 000 cubic kilometres of ash and rock debris into the atmosphere, much of it as fine ash which blocked out solar radiation, kicking the world back into an ice age," he said.
The scientist said super volcanoes represent the greatest potential hazard on Earth, "the only greater threat being an asteroid impact from space".
"A super volcano will definitely erupt," he said. "It could be in a few, 50 or another 1 000 years but sooner or later one is going to go off."
Other super volcanoes are found in Italy, South America, the United States and New Zealand -- where Mount Taupo could be ready for eruption.
"It has a big eruption every 2 000 years, and it last erupted about 2 000 years ago," Cas said.
The potential death toll from a super-volcano eruption "could reach the hundreds of thousands to millions and there are serious implications on climate, weather and viability of food production", Cas said.
"The big problem is a lot of the volcanoes that potentially could erupt are perhaps not monitored to the degree that they should be, and of course we learnt that lesson from the Boxing Day tsunami disaster," he said. -- Sapa-AFP
