The island of Maui evolved from two separate volcanoes that formed the island. The older West Maui Mountains is 1.3 million years old, while the larger, East Maui, also known as Haleakala, is relatively young; last erupting 800 to 1,500 years ago. Although Maui is not likely threatened by lava flows, it is susceptible to vog; a problem that affects people with respiratory problems. Major disasters in Maui County that have been declared by the Governor since 1980 include: heavy rains and flooding on March 30 to April 2, 1981; Hurricane Iniki in September 1992; wildfire on Molokai in 1994 and 1998; and drought on Maui from 1997-1998 and again in July 1999.
