A mass tort is a civil action involving numerous plaintiffs against one or a few corporate defendants. The tort may involve, for example, personal injuries suffered by numerous plaintiffs as a result of a defective product, or a mass disaster in which there were many injured persons, such as an airplane crash, or exposure of a large group of people to toxic chemicals or pharmaceuticals.
Thermopolis is the largest town in and the county seat of Hot Springs County, Wyoming, United States. As of the 2000 census, the town population was 3,172. As might be expected from its name and the name of its county, Thermopolis is home to numerous natural hot springs, in which mineral-laden waters are heated by geothermal processes. It claims the world's largest mineral hot spring as part of Hot Springs State Park. The springs are open to the public for free as part of an 1896 treaty signed with the Shoshone and Arapaho Indian tribes.
