The BBC program was made in the 20th century :). However I just recently read about it, so I decided to blog it. I forgot about good old Krakatoa. Yes, I know this is old news.

Although its old news ;-) Compare these to the scary Krakatoa eruption in 1883 - "The noise was heard over 4600 km away, throughout the Indian Ocean, from Rodriguez Island and Sri Lanka in the west, to Australia in the east .... generated mountainous tsunamis, up to 40 m tall .... Tephra from the eruption fell as far as 2,500 km downwind in the days following the eruption .... the finest fragments were propelled high into the stratosphere, spreading outward as a broad cloud across the entire equatorial belt in only two weeks. These particles would remain suspended in the atmosphere for years, propogating farther to the north and south before finally dissipating .... reflected enough sunlight to cause global temperatures to drop by several degrees. This aerosol-rich veil also generated spectacular optical effects over 70% of the earth's surface. " http://www.geology.sdsu.edu/how_volcanoes_work/Krakatau.html http://en.wikipedia.org/wiki/Krakatoa A supervolcano eruption would be hundreds of times stronger than this. p.s. Your link to "My Delicious" on the sidebar looks nice. Good one Sameer.
