Abstract
Surface water associated with active or potentially active volcanoes can exhibit
physical and chemical changes related to renewed volcanic activity. Measuring
variations in parameters such as temperature, pH, conductivity, and water level
on a regular basis can provide insite into the processes expected to accompany
volcanic unrest. Continuous telemetered monitoring installations at Loowit
Creek, Mount St. Helens, and Kelut crater lake, Indonesia, are examples of the
techniques and equipment that can be used to monitor two different kinds of
surface water at volcanoes.
