|Atsonupuri stratovolcano forms a peninsula jutting into the Sea of Okhotsk. Seen here from the NE, it is joined to the southern end of Iturup Island by a low isthmus only 30 m high. A late-Pleistocene or early Holocene stratovolcano formed an island that was later connected to Iturup. A 2-km-wide caldera was overtopped by a central cone that forms the present 1206-m-high summit. Strombolian eruptions have dominated the history of this basaltic volcano.

|Conical Atsonupuri stratovolcano, it summit dappled by light snowfall, is seen here from the SW. The volcano forms a prominent peninsula joined to the SW side of Iturup Island. A 2-km-wide caldera was subsequently largely overtopped by a central cone that forms the present 1206-m-high summit. Strombolian eruptions have dominated the history of this basaltic volcano, leaving slopes susceptible to slumping and erosion. Only two historical eruptions are known at Atsonupuri, during 1812 and 1932.

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 Etorofu-Atosanupuri [Atosanupuri]||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).|
