These reservoirs consist of a plumbing system of fractures in the rock that convey hot ground water to geysers and hot springs. Changes in this plumbing, either by opening or closing of fractures, can change the flow of water to the geysers, affecting their eruption ,::.:.::-,..’.~, ~ . ~\~ILI,~ ~.... ii:1~ ~i."~::i;~i~’.:::. h; ’ ",i.i :" ." .i . :.1.:~.. :.:..:’,":![.:,:,,:;.::.I",..,
