Natural disasters will become more and more popular

Earth seems to be more active and dangerous than the planet before. Results are provided based on reports published by mass media, based on recent natural disasters. But the more comprehensive view finds that not the natural Mother has changed the climate, but this change depends on people.

By not developing more soil and increasing fertile fertility for the soil, people are increasing the impact on natural disaster prone areas.

This has enabled an increase in the level of natural disasters in areas where events such as earthquakes and storms often occur, leaving heavy physical and human losses. .

In the meantime, when arranging the main natural events that lethal, launched in any year, the damage to life caused by the natural mother had great changes.

How we died

This year, an estimated 61,000 people died from natural disasters, about 50,000 were victims of a 7.6-magnitude earthquake in Pakistan on October 7. Corresponding to this figure, in 2004, 60% of all deaths due to natural disasters were victims of the tsunami in the Indian Ocean.

Debarati Guha-Sapir, director of the Center for Diseases Research in Brussels, Belgium, said. Further, the distribution of natural disasters in 2005 is similar to that of 2004. Despite this, Guha-Sapir has warned that it is still early to make accurate comparisons between two years, note that the December 6 tsunami struck Indonesia and claimed 130,000 lives. Other natural disasters in 2005 left heavy consequences for human life including :

- A serious earthquake of 8.7 richter strikes on Indonesia on March 28 claimed the lives of more than 1,600 people.

- Hurricane Katrina, the storm that struck the Gulf Coast at the end of August, killed more than 1,200 people.

- Hurricane Stan, the storm that caused floods in the countries along South America according to statistics, claimed 1,153 lives when it landed on October 4.

Hurricane Katrina, the storm estimated to have cost about $ 200 billion in damage because of the devastation, the natural disaster that caused the greatest material loss this year. Katrina was also the most devastating natural disaster in American history.

All these statistics have overshadowed many comparisons with the annual deaths caused by war, famine and the spread of disease.

The increase in natural disasters

According to the US Foreign Disaster Assistance Agency (OFDA), CRED has maintained a database of emergency disasters called EM-DAT. An event is categorized into a natural disaster if it kills 10 or more or causes at least 100 people to be injured, homeless, displaced or displaced.

An event will also be in the data warehouse if a country declares it a natural disaster or if that event forces the country to call for international assistance.

According to EM-DAT, a database of emergency natural disasters, the total number of natural disasters annually published has increased steadily in recent decades, from 78 disasters in 1970 to 348 disasters. 2004.

Based on media announcements and Guha-Sapir communications development, the division of disasters for each region did not follow nature. Another base to evaluate began in the 1980s, firms like CRED and the US Agency for International Development began to actively observe natural disasters.

Guha-Sapir said that though, about two-thirds of the increase in nature and the answer of the increase are called meteorological disasters - hydrogen gas. These disasters include droughts, tsunamis, typhoons, tropical storms and floods, which are still growing compared to more than 25 years ago.

In 1980, there were only about 100 natural disasters each year, but this number has increased to over 300 disasters a year since 2000.

In contrast, natural geological disasters such as volcanic eruptions, earthquakes, landslides and avalanches still occur regularly in recent decades.

What will continue?

Scientists believe that the increase in hydrogen-meteorological disasters is the natural result of the link between nature and man-made factors. Global warnings indicate an increase in the temperature of the continents on the earth and the atmosphere, affecting the stronger intensity of the storms.

The transformation of nature in the decade, in the frequent and intense intensity of the storms is also believed to have the contribution of unnatural factors, when unusual changes of the heat layer take place. width in tropical ocean currents in the eastern Pacific Ocean. El Nino and La Nina phenomena are two typical phenomena known due to these changes.

People also increase the impact on nature by rapid and unplanned urbanization in flood prone areas. This increases the likelihood of flash floods and coastal floods destroying cities and human villages.

According to a March report by the World Bank, more than 160 countries have more than three quarters of the population living in areas with one or more natural disasters that cause high rates of casualties.

Taiwan is ranked outside the earth's most vulnerable natural disaster areas with 73% of the country's land area and the total population being placed in 3 or more threatening situations.
