We used low-cost Raspberry Pi ultraviolet (UV) cameras to measure sulphur dioxide (SO2) fluxes from Sabancaya volcano, Peru, during eruptive activity on 27 April 2018. Light dilution corrections were made by operating instruments at two distances simultaneously. Estimated SO2 of 27.1 kgs-1 are higher than previously reported, likely due the current episode (ongoing since November 2016). Each event included frequent (2–3 per minute), ash-rich emissions, forming gas pulses with masses 3.0–8.2...

UV cameras have been used for over a decade in order to remotely sense SO2 emission rates from active volcanoes, and thereby enhance our understanding of processes related passive degassing. Whilst column density retrievals can be more accurate/sophisticated using alternative techniques (e.g., Differential Optical Absorption Spectrometer (DOAS), Correlation (COSPEC)), due their higher spectral resolutions, provide the advantage high time-resolution rates, much greater spatial resolution,...

El propósito de este artículo es determinar brechas que presentan las MiPyMEs la región Coquimbo en el uso SIAs. Del total empresas encuestadas (N=106), sólo un 14% menciona tiene SIA hecho a su medida, 8% usa estándar. Un 52% excel como software para análisis información relevante; lo evidencia una falta profesionalización gestión información, sobre todo si 19% ellas controla manualmente.Las principales identificadas ámbito organizacional son temor desconocido, junto con resistencia al...
