Abstract

Telemetered high-resolution tiltmeters were installed in Montserrat in summer of 1995, in December 1996, and in May 1997. The 1995 installations, several km from the Soufriere Hills vent, were too distnat to yield useful data. However, the 1996 and 1997 installations on the crater rim revealed 6-14 h inflation cycles caused by magma pressurization at shallow depths (<0.6 km below the base of dome). The tilt data correlated with seismicity, explosions, and pyroclastic flow activity, and were used to forecast times of increased volcanic hazard to protect scientific field workers and the general public.
