The Global Volcanism Program has no activity reports for Hankow Reef.
The Global Volcanism Program has no Weekly Reports available for Hankow Reef.
The Global Volcanism Program has no Bulletin Reports available for Hankow Reef.
The Global Volcanism Program is not aware of any Holocene eruptions from Hankow Reef. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Hankow Reef page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.
|Feature Name||Feature Type||Elevation||Latitude||Longitude|
|Hankow Reef Seamount||Cone||-5 m||4° 53' 0" S||146° 43' 0" E|
|South Hankow Seamount||Cone||-231 m||4° 56' 5" S||146° 41' 15" E|
|West Hankow Seamount||Cone||-292 m||4° 52' 58" S||146° 37' 52" E|
|Hankow Reef is partially truncated just below the upper left corner of the cloud-covered portion of this NASA Landsat composite image (with north to the top). The possible existence of a now-submerged volcano named Yomba off the coast of Papua New Guinea is inferred from oral tradition and is considered to likely be at the location of Hankow Reef. The reef lies SE of Bagabag Island (upper left) and NW of Long Island, the larger island at the lower right. Crown Island lies beneath the cloud cover between Long Island and Hankow Reef.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

|Large Eruptions of Hankow Reef||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).|
|WOVOdat||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.|
|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).|
