Understanding the magmatic contribution to hydrothermal systems is essential to full exploitation of geothermal energy. Conversely, hydrothermal systems control the thermal evolution and hence the volcanic life, chemical evolution, and in at least some cases the eruptive behavior of magma systems. We propose to investigate the connection between a well-explored hydrothermal system and an adjacent highly active volcano. The site is selected because of its relative simplicity: A single fault is the geothermal production zone and appears to connect directly with the active magma column, which feeds 700oC fumaroles. 2 Our concept, which is to be the subject of an international workshop, is to directionally drill into the fracture zone at a point intermediate between the active vent and the production field, in order to test the relationship between the two systems. The test will be conducted by comparing the chemical relationship of borehole fluid samples to the fumarolic and geothermal fluids, and by monitoring pressure and temperature in the
