| Abstract | We made continuous gravity measurements at Whakarewarewa Geyser flat using a Scintrex gravimeter and detected particular signals whose amplitude are about 10 This gravity change cannot be explained by the water levels variations in Te pool, but is interpreted to be mainly brought about by changes in water level and steam distribution within the underground reservoir. There are no visual records of geyser activity over the period of our measurements,so we cannot correlate the relationship between the observed signals and the dynamic sequence of geysering. These measurementsrepresent a pilot study for an elaborate gravimetric survey. |
