Geological Summary

The 2 x 3.5 km forested island of Blup Blup contains lava flows with well-defined flow fronts. Weak thermal areas are located on the W and N coasts. Most eruptive activity at the andesitic-dacitic volcano originated from a summit crater about 800 m in diameter, although there may be a lava dome on a ridge to the W and a small satellite cone along the SW coast. Reports of eruptions in 1616 and 1830 are erroneous, but there may have been eruptions during the Holocene (Johnson, 1990 p.c.). Blocks from a submarine debris avalanche lie to the NE of the island.

Eruptive History

There is data available for 0 confirmed Holocene eruptive periods.

[ 1830 ] Discredited Eruption

Sapper (1917) lists Blup Blup as active in 1830, apparently based on Morell (1832), whose account is probably fanciful (Johnson, 1990, p.c.).

[ 1616 ] Discredited Eruption

Schouten and Le Maire almost certainly observed only Manam erupting in 1616, not also Blup Blup as indicated by Sapper (1917) (Johnson, 1990, p.c.).

The small island to the upper left is Blup Blup. This 3.5-km-wide forested island contains lava flows with well-defined flow fronts and a weak thermal area is located on the W coast. No historical eruptions have occurred, but the volcano may have been active during the Holocene. It is part of the Schouten Islands, along with Kadovar volcano (the small circular island to the S) and Bam volcano (right).

The roughly 3.5-km-wide Blup Blup is north of the main Papua New Guinea island. The summit crater near the center of the island is visible in this August 2019 Planet Labs satellite image monthly mosaic (N is at the top). A small flank cone is on the SW coast and a submarine debris avalanche deposit is to the NE.

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.

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.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.

Volcanic Hazard Maps

The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter.

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.

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.
