The vast expanse of Lake Taupō's sky blue waters, crowned by hazy, mountainous horizons, invokes an extreme sense of tranquility.
Lake Taupō is the largest freshwater lake in Australasia, located at the center of New Zealand's north island. And while it appears peaceful today, the lake has a violent origin story.
It's the supervolcano's more modern periods of unrest that the researchers have studied, analyzing up to 42 years of data collected at 22 sites dotted around and across the lake. And there's evidence that the supervolcano is still rumbling."In 1979 [researchers] began a novel surveying technique which uses the lake surface to detect small changes, with four surveys made every year since," lead author and Victoria University of Wellington seismologist.
In early 1983, the system detected rising or falling across different sites. Not long after, a swarm of earthquakes gently shook the region, resulting in the rupturing of several faults that pushed the central Kaiapo fault belt down and caused other areas at the lake's south end to rise.The 1983 earthquake swarms were only the first of seven discreet episodes of unrest recorded over the past 35 years.
"Within the lake, near Horomatangi Reefs, the volcano has caused 160 mm [16 cm or 6.3 inches] of uplift, whereas north of the lake the tectonic faults have caused 140 mm [5.5 inches] of subsidence,"He thinks this region, which has very few earthquakes compared to the surrounding areas, is the location of Taupō 's magma reservoir, with deep rock that is too hot and molten for earthquakes to occur.
