Question:
What tools do volcanologist use?



Replies:
The University of North Dakota's Volcano World web site says:

"Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seimographs), instruments that measure ground deformation (EDM, Leveling, GPS, tilt), instruments that detect and measure volcanic gases (COSPEC), instruments that determine how much lava is moving underground (VLF, EM-31), video and still cameras, infrared cameras and cameras that work remotely. This is by no means a complete list, volcanologists will use whatever tool they can to help them understand volcanoes."
