Geological Summary

Taupo, the most active rhyolitic volcano of the Taupo volcanic zone, is a large, roughly 35-km-wide caldera with poorly defined margins. It is a type example of an "inverse volcano" that slopes inward towards the most recent vent location. The caldera, now filled by Lake Taupo, largely formed as a result of the voluminous eruption of the Oruanui Tephra about 22,600 years before present (BP). This was the largest known eruption at Taupo, producing about 1,170 km³ of tephra. This eruption was preceded during the late Pleistocene by the eruption of a large number of rhyolitic lava domes north of Lake Taupo. Large explosive eruptions have occurred frequently during the Holocene from many vents within Lake Taupo and near its margins. The most recent major eruption took place about 1800 years BP from at least three vents along a NE-SW-trending fissure centered on the Horomotangi Reefs. This extremely violent eruption was New Zealand's largest during the Holocene and produced the thin but widespread phreatoplinian Taupo Ignimbrite, which covered 20,000 km² of North Island.

Photo Gallery

An aerial view shows the east margin of Lake Taupo with Taupo City on its shores. 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 prominent peak in the background.

Photo by Jim Healy (New Zealand Geological Survey).

Volcanologists Colin Wilson and Peter Bellance examine a roadcut that dissects deposits of major eruptions from the Taupo volcanic center. The unit at the level of the feet of the volcanologists 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 airfall-pumice deposits from other major eruptions occur between it and the deposits of the 1800-year-old Taupo eruption (upper right), which were responsible for Taupo's second caldera.

Photo by Bruce Houghton (Wairakei Research Center).

This telephoto view looking SW across Lake Taupo, the southernmost major caldera of the Taupo volcanic zone, shows several major peaks anchoring the southern end of the Taupo volcanic zone. The broad forested peak below the center horizon is the Pleistocene Pihanga volcano. The steep-sided cone on the horizon to its right is Nguaruhoe, the youngest volcano of the Tongarior complex. The broad massif to its right is Tongariro. The snow-capped massif on the left-center horizon is Ruapehu.

Lake Taupo fills a topographically indistinct, 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 1800 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.

Photo by Richard Waitt, 1986 (U.S. Geological Survey).

This thick outcrop exposes deposits of the 1800-years-old Taupo eruption, one of the world's largest during the past 10,000 years. The Taupo eruption produced nearly 100 cu km of phreatomagmatic surge deposits, plinian airfall-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.

MIROVA

Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.

MODVOLC Thermal Alerts

Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.

Sentinel Hub Playground

The Sentinel Hub Playground provides a quick look at any Sentinel-2 image in any combination of the bands and enhanced with image effects; Landsat 8, DEM and MODIS are also available. Sentinel Hub is an engine for processing of petabytes of satellite data. It is opening the doors for machine learning and helping hundreds of application developers worldwide. It makes Sentinel, Landsat, and other Earth observation imagery easily accessible for browsing, visualization and analysis. Sentinel Hub is operated by Sinergise

IRIS seismic stations/networks

Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Taupo. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice.

UNAVCO GPS/GNSS stations

Geodetic Data Services map from UNAVCO showing the location of GPS/GNSS stations from all available networks (permanent or temporary) within a radius of 20 km from the given location of Taupo. Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player.

DECADE Data

The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO₂ to the atmosphere, but installing CO₂ monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere.

WOVOdat
   Single Volcano View
   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

Large Eruptions of Taupo

Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

EarthChem

EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).
