what kind of tools aRE used to measure a volcanic eruption
Volcanologists use a device called a tiltmeter to measure tiny changes in the angle of the volcano's slope that might indicate a build-up of gases below the surface that could result in an eruption.These changes are too small to be seen by the eye but can still indicate that an eruption is imminent.he most basic tool used by any volcanologist is a simple rock hammer, used for breaking off samples of igneous rock for laboratory analysis. Other samples are collected from the volcano's core using a drill.
Measuring Volcanic Gases. Because volatiles play an important role in the generation, evolution and eruption of magma, it is critical that we use various tools to monitor gases both within and emitted from a volcano.he spectrometer is designed to measure the concentration of sulfur dioxide (SO2) in the volcanic plume that is emitted from the volcano. The device requires a standard, from which to analyze the ultraviolet light absorbed by the SO2 molecules in the plume.
