Japanese National Earthquake Hazard Map (IMAGE)
Caption
Here is a comparison of Japanese national earthquake hazard map (top) to uniform and randomized versions. The map predicts the level of shaking, shown by colors from red (highest) to white (least) expected to be exceeded at 5% of the sites on the map in the next 50 years. Surprisingly, by the most commonly used measure, the uniform and randomized maps work better than the published maps.
