Pictures from Europe's Mars Express Orbiter

This is Olympus Mons. At 22 kilometers (14 miles) tall, it's three times the height of Mt. Everest. It measures 550 km (342 miles) across, covering an area about half the size of Spain. The color pictures are looking down into the caldera, which is three km deep itself.
TrackBackCan you imagine the force of the explosion that created this?
Kaboom.
Posted by: apostropher at February 16, 2004 02:49 AMKaboom is right, could you imagine trying to stand up straight when it blew? The ground would most likely make you fall on your ass...LoL
Posted by: Ian Lehr at April 8, 2004 04:15 PMBy the look of the slope and the shape of the caldera, I would say that there was not much "kaboom" involved. If so, it would have a shape more like Mt. St. Helens. But the shape is more like the Mauna Loa volcano, which "fountains and flows" more than it "kabooms".

Posted by: louis at May 14, 2007 02:22 PMthe biggest volcano on earth is super volcano in yellow stone park it is under yellow stone. if it blows up thier will be ash that will cover the whole planet and will cause another ice age and it will kill most the peole in the world . scientist think it will blow up soon.we will also proble see mounte st.helen erupt in are life time and mabe even 5 more my science teacher said so.
Posted by: daisy at December 24, 2007 02:07 PMyes it will put ash but not the ice age coz the sun will still heat up earth

Posted by: o at October 13, 2008 12:45 PMOlympus Mons is a shield volcano that extrudes Basalt, this means it dosnt explode at all, lava runs down the sides which makes it the gradual sloping shape. If it had steep sides, or was just a caldera by itself (like lake taupo in New Zealand) then it would be the explosive sort of volcano. (needs a complete differnt sort of lava too by the way..)
And Mt St Hellens is not as silicic as Chaiten volcano in Chile, which just erupted in may. This could be the most explosive volcano weve ever seen, possibly as big as Krakatoa or Taupo even, if it continues to erupt and then forms a caldera.
That would be 'boom', and cause major global cooling probably.
