Some lasers emit radiation in the form of light. Others emit radiation that is invisible to the eye, such as ultraviolet or infrared radiation. In general, laser radiation is not in itself harmful, and behaves much like ordinary light in its interaction with the body.
Hurricane Katrina is arguably the most notorious storm of the 21st century. The storm made landfall as a Category 5 near Miami before striking Louisiana as a Category 3 storm. Katrina was the third deadliest, and costliest hurricane in US history with more than 1,200 deaths and $108 billion in damage.
Hurricane Andrew was not the deadliest tropical cyclone to strike the U.S. mainland, but the compact, fast-moving storm remains one of the strongest and costliest on record.hile storm surges often cause the bulk of damage during hurricanes, in Andrewâs case, high wind speeds proved most destructive. Whole neighborhoods were flattened and thousands of homes lost their roofs; more than 90 percent of mobile homes in affected areas were destroyed.
