Storms, floods, earthquakes, tsunamis -- with more than half the world’s population now concentrated in cities, the economic threat of natural disasters in metropolitan areas looms ever larger.

The 2011 earthquake and tsunami in northern Japan set a new standard for disaster with almost 20,000 people killed and a record $300 billion in economic losses. Later that year, Bangkok broke the cost record for freshwater floods, with $47 billion in losses. A year later Hurricane Sandy caused $60 billion in storm-surge damage in New York and New Jersey. 

A new report by Swiss Re Ltd., the world’s second-biggest reinsurer, ranks 616 metro areas by the value of working days at risk from five natural perils, as well as by number of residents potentially affected.
