The built-up surface potentially exposed to tsunami in Japan is 2 times the sum of built-up in the other 9 most exposed countries

EARTHQUAKE
TSUNAMI
TROPICAL CYCLONE WIND
VOLCANO
Population potentially exposed to earthquakes on the planet increased from 1.4 to 2.7 billion between 1975 and 2015
China and Japan are by far the countries with the largest built-up surface exposed to strong cyclone winds (>178 km/h)
In 2015, 414 million people lived near one of the 220 most dangerous volcanoes and could be affected by the consequences of eruptions
FLOOD
CYCLONE STORM SURGE
Flood, the most frequent natural hazard, potentially affects people in Asia and Africa more than in other regions
Population exposed to sea level surge due to cyclones in China approximates the sum of the exposed population of India + Japan + the Philippines
