Natural disasters can strike any city at anytime, but some cities are more at risk than others. Tokyo and San Francisco are the cities facing the biggest damage potential from natural disasters such as earthquakes, Bloomberg reports of a new study issued by Munich Re, the world's largest reinsurer.

The cities with the biggest risk have one thing in common: They are megacities with metropolitan areas of more than 10 million people. In addition to natural disasters, which can affect any city, big cities face a greater risk of damage from industrial accidents, air disasters, and terrorism.

Munich Re developed a natural hazard risk index to calculate the danger of natural disaster in a given area as well as the value that may be destroyed. No 1. Tokyo scored 710 points, while San Francisco was a distant No. 2 with 167 points. Tokyo's risk was the highest due to its huge population and a high risk of earthquakes, along with lower levels of risk from storm damage, volcanic eruption, and tsunamis.
