Hawaii still has several active volcanoes. For example, the Kilauea volcano has been erupting almost continuously since 1983.
Droughts in the United States are quite rare, but if they do happen, they are catastrophic. It is assumed that it was the drought, which began in the 12th century and lasted for several centuries, that caused the disappearance of the Anasazi people, known for creating the Mesa Verde rock house complex.
The infamous drought that lasted from 1931 to 1942 in the southwestern United States and exacerbated the economic recession in the country, known as the “Great Depression”. The drought was accompanied by a series of severe dust storms, called the “Dust Bowl”. Over vast areas, the top, fertile layer of soil was blown away by the winds; hundreds of thousands of people were forced to leave their usual places. The dust storms of the thirties were caused by both natural and anthropogenic factors, in particular, a sharp increase in the area of arable land without any anti-erosion measures. The states of Texas and Oklahoma suffered the most then, as well as Kansas, Colorado and New Mexico.
Like droughts, floods in the United States are rare, but their consequences are very serious. Notorious were the floods on the Mississippi River in 1927 and 1993.
The “Great Mississippi Flood”, considered the most catastrophic in the history of the United States of America, occurred in 1927. Back in the fall of 1926, due to prolonged downpours, the tributaries of the Mississippi were ready to overflow their banks. In the spring, heavy rains again occurred, the then existing system of protective dams was broken in at least one hundred and forty-five places, and water gradually flooded more than 70,000 km 2. The states most affected then in the lower reaches of the river – Arkansas (14% of whose territory was flooded), Louisiana and Mississippi; to a lesser extent – Illinois, Kentucky, Missouri, Tennessee, Texas, Oklahoma and Kansas. During the “Great Mississippi Flood” about five hundred people died, hundreds of thousands of people (mostly blacks) lost their homes, losses amounted to about a billion dollars, which at that time was about a third of the US federal budget. To prevent this from happening in the future, the US federal government later built the world’s longest protective dam system.
