Evidence for fluid bodies beneath the Sulphur Springs Geothermal Region, St. Lucia, West Indies

Abstract
During a 39‐day microearthquake survey in the Sulphur Springs geothermal region, St. Lucia, seven local hypocenters were determined. Emergent P onsets and missing S‐waves were observed for five of these, and attenuated S‐waves recorded for two regional events. These imply the presence of at least two significant fluid bodies beneath the area. Ground noise measurements near natural steam vents suggest a deep source for the steam.
