The United States is a huge nation and natural disasters occur frequently.
Forests, forests, high deserts, even tundra, as well as various elements caused by the horns, moons, air, and even the nuclei of the earth create natural disasters.
The United States is the second largest tornado and active volcano in the world after Indonesia.
It is also less severe than by tornadoes and volcanoes, but the damage from heatwaves is also serious.
Geologic factors and rapidly changing weather, which vary from region to region, result in some natural disasters and disasters in the United States.
Strong storms, wildfires, landslides, avalanches, sinkholes, blizzards, floods, droughts, heatwaves, earthquakes, volcanoes, and tornadoes can pose a risk at any time of the year.
"There are a number of places where there are really many natural disasters in some parts of the country," said David Applegate, deputy director of the US Geological Survey.
So what is the most dangerous natural disaster?
Susan Cutter said it depends on what he focuses on, and with fellow researchers, he investigated deaths and injuries from natural disasters in the United States since the 1960s.
As a result, natural disasters since 1960 have been the worst hit by Florida. The most disastrous natural disaster in Florida was a hurricane, plus floods and wildfires.
California has suffered the most damage after Florida in financial losses due to natural disasters such as forest fires, earthquakes, floods, and storms, and all kinds of natural disasters in the United States appear to have appeared in California. Louisiana suffered the most financial damage after California.
The large financial damage caused by natural disasters did not mean that the casualties were large. The most common deaths were natural disasters in Texas due to severe flooding and weather, followed by heatwaves such as the notorious Chicago heatwave in 1995 in the state of Illinois.
Cutter says that in the next few decades, considering the future of natural disasters in the United States, climate change will change the topography of natural disasters in the United States.
Cutter predicts that natural disasters such as volcanic and earthquakes, which are caused by geophysical causes, will remain as they are due to climate change, but everything else will change.
