It depends, if you want to account for human damage, damage to life, or natural damage.
Anything that causes flooding is at great damage to human towns and cities, because the water in homes can be very hard to get rid of, even now people whos houses were flooded last year have still got damp in their houses.There are people who have still no gone back to living normal lives from that.
For something to be really damaging to human life I would say famines. Not enough aid is ever dropped and people will always die, and keep on dieing because there will be no harvests.
For damage to nature I would say that volcanic eruptions are worse than all because if we take Mt. St Helens for example, miles of forests were blown to pieces, ash and dust fell from the sky, taking only 3 days to go round the entire world with it's ash. That ash fell and damaged habitats all over the world.
((Damn it, I don't even need to know this for my Geography course any more. This was the only part of Geography I paid any attention to))

To be perfectly honest most disasters are only amplified by human activity. If all known flood plains are never built on, then there would be next to no flooding. If no one built on a fault line, or built solid tall buildings that fall, if the earthquake is strong at the surface (same goes for volcanoes too). If no one built next to the sea then neither Tsunamis or Hurricane/Typhoon would be a problem.
