Most Recent Weekly Report: 24 May-30 May 2023 Citation IconCite this Report

GeoNet reported that earthquake activity and ground deformation at Taupo declined during January-April and returned to background levels in May. The Volcanic Alert Level was lowered to 0 (the lowest level on a six-level scale) on 30 May and the Aviation Color Code remained at Green (the lowest level on a four-color scale). Unrest at the volcano started in early May 2022; during the year there were just over 1,800 earthquakes located beneath the volcano along with ground deformation both on the lake floor and around the lake.

30 November-6 December 2022 Citation IconCite this Report

GeoNet reported that a strong M 5.6 [later revised to 5.7] earthquake occurred beneath Taupo on 30 November. The event was widely felt and caused a small tsunami in the lake. Lake water inundated the shore at several locations, mostly along the N shore, traveling inland as far as 40 m at Wharewaka Point (along the NE shore). Both the earthquake and the tsunami caused minor local damage. The instrument at Horomatangi recorded 250 mm of horizontal ground movement towards the SE, the largest movement ever recorded at that location. Other onshore stations recorded smaller movements of around 10-20 mm. More than 600 aftershocks were located by 7 December, though the magnitude and rate of the events had begun to decline. The largest aftershock was an M 4.5 and two other M 4 events were also recorded.

Earthquakes larger than M 5 beneath Lake Taupo had occurred only four times since 1952, including a M 5 event that occurred on 4 September 2019 as part of a previous period of volcanic unrest. GeoNet noted that there had been 17 previous episodes of unrest at Taupo over the previous 150 years, some more notable than the current episode, and many others before written records. None resulted in an eruption, with the last eruption occurring around 232 CE. The Volcanic Alert Level remained at 1 (the second lowest level on a six-level scale) and the Aviation Color Code remained at Green (the lowest level on a four-color scale).

21 September-27 September 2022 Citation IconCite this Report

On 28 September GeoNet reported that seismic unrest and deformation at Taupo continued during the previous week. About 750 earthquakes have been located at depths of 4-13 km beneath the lake since unrest began in May. During the past week the locations were concentrated beneath the E part of the lake and occurred at a slightly lower rate than the week before. An area of deformation at Horomatangi Reef had been rising at a rate of 60 mm (plus or minus 20 mm) per year since May. The data suggested that the seismicity and deformation was caused by the movement of magma and hydrothermal fluids. GeoNet noted that unrest at calderas was common and may continue for months or years without resulting in an eruption; more significant unrest would be indicated by additional indicators of activity and substantial impacts on the local area. The Volcanic Alert Level remained at 1 (the second lowest level on a six-level scale) reflecting “minor volcanic unrest” characterized by ongoing seismicity and inflation.

On 20 September GeoNet raised the Volcanic Alert Level for Taupo to 1 (the second lowest level on a six-level scale) reflecting “minor volcanic unrest” characterized by ongoing seismicity and inflation. Seismicity beneath Lake Taupo began increasing in May. Earthquakes occurred at a rate of about 30 per week but increased to about 40 per week in early September. A M 4.2 earthquake, the largest so far this year, was recorded on 10 September and felt by over 1,000 people. By 20 September over 700 earthquakes had been located with depths less than 30 km, though most ranged 4-13 km. The earthquake locations were in two clusters: a larger cluster beneath the central and E part of the lake, and a smaller cluster to the W centered just offshore from Karangahape. An area of deformation at Horomatangi Reef had been rising at a rate of 60 mm (plus or minus 20 mm) per year since May. The area of uplift corresponded to the main seismic swarm. The data suggested that the seismicity and deformation was caused by the movement of magma and hydrothermal fluids.

GeoNet noted that unrest at calderas was common and may continue for months or years without resulting in an eruption; more significant unrest would be indicated by additional indicators of activity and substantial impacts on the local area. There have been 17 previous episodes of unrest at Taupo over the previous 150 years, some more notable than the current episode, and many others before written records. None resulted in an eruption, with the last eruption occurring around 232 CE. The Volcanic Alert Level change was informed by ongoing analysis of monitoring data, research, and deepening knowledge of past unrest.

An aerial view shows the E margin of Lake Taupo with Taupo City on its shore. The 35-km-wide caldera is not topographically prominent but has been the source of powerful rhyolitic eruptions from the late Pleistocene throughout the Holocene. The 35,000-year-old Tauhara lava dome forms the peak in the background.

Volcanologists Colin Wilson and Peter Ballance examine a roadcut that dissects deposits of major eruptions from the Taupo volcanic center. The bottom visible unit is an exposure of an unwelded pyroclastic flow deposit from the Oruanui eruption, which formed Taupo's initial caldera about 22,600 years ago. Light-colored pumice fall deposits from other major eruptions are between it and the deposits of the 1,800-year-old Taupo eruption (upper right), which were responsible for Taupo's second caldera.

This view looking SW across Lake Taupo, the southernmost major caldera of the Taupo Volcanic Zone, shows several major peaks of Tongariro and Ruapehu. The broad forested peak below the center horizon is the Pleistocene Pihanga volcano. The steep-sided cone on the horizon to its right is Ngāuruhoe, the youngest cone of the Tongariro complex. The broad massif to its right is Tongariro. The snow-capped massif on the left-center horizon is Ruapehu.

Lake Taupo fills a roughly 35-km-wide caldera that is the site of the most prolific rhyolitic volcano of the Taupo volcanic zone. The caldera was formed during two major explosive eruptions, the Oruanui eruption, roughly 22,600 years ago, and the Taupo eruption, about 1,800 years ago. The latter was one of the world's largest Holocene eruptions. Additional Plinian eruptions during the Holocene have produced widespread airfall pumice deposits.

This thick outcrop exposes deposits of the 1,800-year-old Taupo eruption, one of the world's largest during the past 10,000 years. The Taupo eruption produced phreatomagmatic surge deposits, Plinian tephra deposits, and the overlying Taupo ignimbrite, seen at the upper half of this photo above the thin, light-colored layers. The eruption occurred from a vent at Horomatangi Reefs, now submerged beneath Lake Taupo.
