Lake bed of volcano, which has been active 25 times in the past 12,000 years, constantly rising and falling, 43 years of data shows
The lake bed of one of the world’s most hazardous supervolcanoes – New Zealand’s Lake Taupō – is constantly rising and falling, proving the volcano is still very much active, nearly half a century of data has revealed.
The team hung specially made water gauges from 22 fixed points and used the purpose-built platform to take into account lake level changes. This method allowed them to detect station height changes as small as 8mm.Photograph: Peter Otway “My Kinloch station [10km west of the town of Taupō], which had been very slowly subsiding, began to rise steadily, finally reaching 50mm by mid-June, by which time I had issued a series of reports,” he said.
The 43-year-long data set has since shown that movements of magma and tectonic faults beneath the surface frequently cause the ground surface above the volcano to uplift and subside, said Dr Finnigan Illsley-Kemp, a postdoctoral fellow in volcano geodynamics at Victoria University of Wellington and a co-author on the paper.
“We would expect the inflation [the increasing pressure in the magma that can cause the surface to bulge] to accelerate rapidly before the next eruption, so it is essential that the deformation continues to be closely monitored.”
