a sudden release of energy in the Earth's crust

that creates seismic waves.
Craft of the earthquakes is measured by the moment magnitude scale and Richter scale. The earthquake with magnitude 3 and lower is called as imperceptible and one with magnitude 9 and over is called serious.

of the ground. When the epicenter of a large

earthquake is located offshore, it’s a reason for tsunami and volcano activity.

The areas, where

the earthquakes occur

are any uncontrolled fire, which occurs in forests from

the middle summer to autumn begin.

flood is an overflow of an expanse of water

that submerges land. In April 2011, two major storm systems deposited record levels of rainfall on the Mississippi River watershed. When that additional water combined with the springtime snowmelt, the river and many of its tributaries began to swell to record levels by the beginning of May. Areas along the Mississippi itself experiencing flooding include Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.

Beaufort scale (equal to or exceeding 64 knots or 118 kph)
Beaufort scale is a scale of wind speed based on a visual estimation of the wind's effects, ranging from force 0 (less than 1 knot or 1 kph, "calm") to force 12 (64 knots or 118 kph and above, "hurricane")

Hurricanes

Western Hemisphere tropical cyclones that exceed the intensities of

tropical depressions and tropical storms — into five categories distinguished by the intensities of their sustained winds. To be classified as a hurricane, a tropical cyclone must have maximum sustained winds of at least 74 mph (33 m/s; 64 kn; 119 km/h) (Category 1). The highest classification in the scale, Category 5, is reserved for storms with winds exceeding 156 mph (70 m/s; 136 kn; 251 km/h).
Hurricanes occur in the late summer and early autumn along southern parts of the east coast and the Gulf of Mexico coast.

city of Galveston in the U.S. state of Texas,

on September 8, 1900. It had estimated winds of 145 miles per hour (233 km/h) at landfall, making it a Category 4 storm on the Saffir–Simpson Hurricane Scale. It was the deadliest hurricane in US history, and the second costliest hurricane in US history based on the US dollar's 2005 value (to compare costs with those of Hurricane Katrina and others).

strengthened to hurricane status 1210 miles (1950 km) east-southeast

of the Lesser Antilles. Ivan had rapidly strengthened to a strong category three hurricane (nearly a category four) on the Saffir-Simpson Hurricane Scale with winds of 125 mph (200 km/h). September 16 Ivan struck the US mainland near Gulf Shores, Alabama. At the time, Ivan's maximum sustained winds had dropped to 130 mph (210 km/h), just under Category 4 strength

Hurricane Ivan

hurricane ever recorded and the most intense tropical cyclone

ever observed in the Gulf of Mexico. Rita caused $12 billion in damage on the U.S. Gulf Coast in September 2005. Rita was the seventeenth named storm, tenth hurricane, fifth major hurricane, and third Category 5 hurricane of the historic 2005 Atlantic hurricane season. It came through Bahamas, Cuba, Florida, Louisiana and Texas.

destructive Atlantic hurricane of the 2005 Atlantic hurricane season.

It is the costliest natural disaster, as well as one of the five deadliest hurricanes, in the history of the United States. Among recorded Atlantic hurricanes, it was the sixth strongest overall. At least 1,836 people died in the actual hurricane and in the subsequent floods, making it the deadliest U.S. hurricane since the 1928 Okeechobee hurricane; total property damage was estimated at $81 billion (2005 USD), nearly triple the damage wrought by Hurricane Andrew in 1992.
