We made SO2 emission rate measurements at Lascar and Villarrica, two of Chile’s most active volcanoes, during a period of two months; these being the first DOAS measurements ever made at these volcanoes. Collaborations with groups in Argentina (Instituto Geonorte - Universidad Nacional de Salta) were continued and those with the groups in Chile (Universidad Catolica del Norte and the Observatorio Volcanologico de los Andes del Sur - OVDAS) and Italy (Universita degli Studi di Firenze) were started. As a result of these collaborations, we are planning for another field campaign in the next year and OVDAS has expressed their interest in the installation of at least two DOAS sites to monitor the activity of Villarrica volcano. In addition to going back to Chile for another field season, I will use the mini-DOAS to measure SO2 loss rates at the Sourfriere Hills volcano, Montserrat and probably at Pacaya, Santa Ana, and Masaya volcanoes, in Central America, as well as Etna volcano, Sicily.
