The activity is continuously monitored by two sequence cameras. Samples of the tephra from around the vent have been studied, temperatures were measured, and ground observations were made of the new fumaroles. Every three months a flight is made over the volcano for aerial photography and infrared scanning. Field studies in the Southern Cascade Mountains were begun to determine the petrochemistry, mode of eruption, and volume of erupted materials for the last 0.5 million years. This study will be used to evaluate the present thermal state and composition of magmas below the range. Investigations ofactive volcanoes and their eruptions will provide data for geothermal research on the physical properties of the magma. (auth)Read More
