Natural disasters such as earthquakes, tsunamis, and floods can often come at the least expected time.Others, such as hurricanes are increasing in severity and destruction.Typically, those poor countries are the worst hit for they have the least resources to deal with the destruction and rebuild their home.This part of the globalissues.org website looks at some of these issues.

Japan Earthquake, Tsunami and Nuclear Crisis

The earthquake off the coast of Japan on March 11, 2011 was one of the biggest recorded, measuring 9 on the Richter scale(里氏震级).

It was the resulting tsunami, however, that caused the most destruction.It devastated the northeast of Japan, leaving many thousands dead or missing, and -hundreds of thousands homeless or leaving the area.In addition, various power generators(发电机组) failed.Some older nuclear power stations risked meltdown and suffered explosions and radioactive leaks.Workers battled for weeks to try and bring the situation under control.Radioactive material was detected in various places.

It is thought that the cost of the earthquake and tsunami could be over $ 300 billion-the world's most expensive natural disaster on record.

Hurricane Katrina

Hurricane Katrina was a destroyed category 4(四级) hurricane, the highest category, that hit the Gulf of Mexico and various Southern regions of the United States at the end of August, 2005, causing the worst damage in that country's history, estimated at $ 100 billion.The famous New Orleans city and surrounding areas were worst hit as much of it sits some 6 feet below sea level.City defenses, such as banks, only designed for categary 3 type hurricanes, gave way, leading to enormous flooding and associated damage, death and displacement of around 100, 000 people who either chose to say the course, or could not afford to flee.
