Some statistics on disasters worldwide
Posted by Dave Petley
Yesterday was the annual United Nations International Day for Disaster Reduction, which this year had a strong urban theme. To highlight the event, which has been somewhat overshadowed by the extraordinary rescue of the Chilean miners, UNISDR put out a press release highlighting the costs of disasters worldwide. The statistics are somewhat sobering:
- So far in 2010 more than 236,000 people have been killed in disasters
- 256 million people have been affected by disaster events, mostly in urban areas
- The cost of disasters in the first nine months of this year is US$81 billion. Most losses are uninsured
With regard to the vulnerability of urban areas:
- More than a billion people live in urban slums
- An estimated 3,351 cities are situated in coastal zones that are potentially vulnerable to sea level rise
- Six of the ten largest cities are in seismically active areas
To mark the day, Xinhua released statistics on disaster impacts in China this year to date:
- Floods, landslides and mudslides have killed 3,313 people so far this year
- 15.7 million people have had to relocate
- Economic losses are estimated to be a staggering US$55.4 billion
