Figure 7From: The scientific–community interface over the fifteen-year eruptive episode of Tungurahua Volcano, Ecuador Plots of tiltmeter data from the electronic tilt station, Retu, located on the NW flank of Tungurahua at 4000 meters elevation. The pattern of a pronounced inflationary trend than followed by a strong downgoing “deflationary” pattern of tilt on the radial axis has been a guide for IGEPN scientists to be alert for onset of Vulcanian eruptions. Dates in boxes are onset of main Vulcanian eruptions.Back to article page
