Abstract
The amount of sulphur dioxide (SO 2 ) emitted in 2008 during the ascent and extrusion of a lava dome in Galeras volcano was estimated and the behavior of emissions was compared with other parameters such as earthquakes associated with fluid motion and volcanic deformation. The flux of SO 2 is the parameter that begins to show the rise of the 2008 lava dome, the other parameters reflect similar behavior but with time lags. Using a wind speed average value of 5 m/s, was estimated that 334.947 tons of SO 2 were emitted into the atmosphere, equivalent to 2,2% of the global total annual volcanic emissions and 15,9% of the annual emissions of the South America subduction zone volcanoes. Keywords: Galeras volcano, Sulphur Dioxide, lava dome.

Summary
Mediante la combinación de las dos trayectorias de medición que están en ángulo recto entre sí, se obtienen los resultados de medición de la suma y el ángulo del vector de velocidad del viento. Para mediciones de inclinación del suelo en monitoreo volcánico, los sensores de burbuja usualmente están adosados a una placa base de aluminio de forma triangular con tornillos nivelantes, adicionalmente disponen de un sensor de temperatura y todo el sistema está cubierto por un domo protector de aluminio (Jewell Instruments, 2016). Para registrar la sismicidad volcánica se utilizan sismómetros, en este caso un sensor de componente vertical de corto periodo instalado en la estación Anganoy, localizada a 0,8 km al oriente del cráter activo de Galeras a una altura de 4170 m. La salida de la bobina es proporcional a la velocidad de la masa relativa al marco y por lo tanto a este tipo de sismómetros electromagnéticos se les llama transductores de velocidad (Havskov and Alguacil, 2002)
