That the name "Taftan" may be derived from an ancient Iranian word "taft" for "semi solid liquid material" could indicate that effusive activity was witnessed by the people of that time period around the volcano.

Chiles (volcano) Chiles (volcano) Chiles is a volcano on the border of Colombia and Ecuador. It lies south-east of the volcano Cerro Negro de Mayasquer, and the two peaks are considered part of the same Chiles-Cerro Negro volcanic complex. The volcanoes, together with the Cumbal are andesitic in rock type. A 1936 eruption reported by the Colombian government agency Ingeominas may have been from the Ecuadorean volcano Reventador, otherwise the volcano has not erupted for around 160,000 years. On 20 October 2014, the Servicio Geológico Colombiano (SGC) reported that a M 5.8 earthquake, the largest to date, occurred in the vicinity of
