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.
Dos Rios (also, Two Rivers - which is its English translation) is an unincorporated community in Mendocino County, California. It is located 7 miles (11 km) east-southeast of Laytonville, at an elevation of 961 feet (293 m). The Two Rivers post office opened in 1912 and changed its name to Dos Rios in 1915. The name comes from the place's proximity to the confluence of the Middle Fork of the Eel River with the Eel River proper.
