What is the most deadly of the natural disasters? If it's as hot where you are as it is where I am, you probably answered correctly. The heat wave:

"The most deadly heat wave in recent years occurred in Chicago over a week in July 1995, when temperatures hovered around 100 degrees. Then, over 50,000 people were left without electricity, nearly two dozen hospitals closed their doors to new patients, ambulances lined up around the block waiting to drop off victims, and the county buried 68 people in a 160-foot-long trench. Though there was some argument over numbers, scientists now say that 739 people died that week.

For context, the great Chicago fire of 1871 killed half that many. The San Francisco earthquake of 1989 killed 62, and Hurricane Andrew in 1992 killed 26."
