同时研究了黄石国家公园内几个间歇泉，特别是老忠实间歇泉的地震和蒸汽活动。在老忠实火山喷发周期中有三个明显的阶段：喷发之后，持续的蒸汽活动和没有地震活动;蒸汽和地震活动一起增加或减少;下一次喷发之前，没有蒸汽或地震活动。这三个阶段被认为是指示地下水库分别充满水，加热和过热，从而引发喷发。对其他八个间歇泉的有限研究表明，每个间歇泉都有其独特的地震特征。
Seismic and steam activity associated with several geysers in Yellowstone National Park, especially Old Faithful geyser, were studied simultaneously. Three distinct phases were evident in the Old Faithful eruption cycle: following an eruption, continuous steam activity and no seismic acivity; steam and seismic activity increasing or decreasing together; and directly preceding the next eruption, no steam or seismic activity. The three phases are believed to be indicative of the filling of the underground reservoir with water, heating, and superheating, respectively, which triggers the eruption. A limited study of eight other geysers suggests that each has its individual seismic signature.
