The poorest are hit the hardest
The earthquake in Nepal in 2015 completely destroyed 600,000 houses. A further 300,000 were severely damaged. Typhoon Haiyan in 2013 on the Philippines made 4 million people homeless.
The most important reasons for the enormous damage after natural disasters in developing countries are poverty and a lack of education. The people affected are forced to build their houses from the resources which are available. This means that the buildings are usually neither earthquake-proof nor can they withstand high wind speeds. People often lack the knowledge how to build robustly and safely so that the buildings can withstand future disasters.
