I visited Colombia in March 2016 as part of the STREVA project. Our group had a number of aims: (i) carry out community workshops regarding lahar hazard and risk reduction, (ii) visit areas that have been previously impacted by lahars around Nevado Del Ruiz (5311 m) and Cerro Machin (2650 m) volcanoes, (iii) host public screenings of the STREVA risk communication videos that commemorate the 1985 Armero disaster, and (iv) plan for future visits to the country. Fortunately, aim (iv) came to fruition in a follow-up visit in September 2016, where I helped to run an InSAR workshop at the Servicio Geológico Colombiano in Pasto, and also visited Volcan Azufral.
