| The eruption of 70-80 km3 of tephra accompanied formation of the caldera, 14C dated to 9,460 ± 50 and 9,400 ± 50 BP (Melekestsev et al., 1988); calibrated ages for that analysis are 10,480-10,780 cal BP (Razzhigaeva et al., 2016), or 8680 ± 150 BCE. Smirnov et al. (2025) noted that Degterev et al. (2015) reported 14C ages "corresponding to the end of the late Pleistocene" of 12,260 ± 220 and 12,360 ± 170 cal BP (combined here as calendar dates 10335 ± 245 BCE). | ||||||||||||||||||||||||||||||||||

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. |
| EarthScope Consortium SAGE seismic stations/networks | EarthScope Consortium operates the NSF Geodetic Facility for the Advancement of Geoscience (GAGE) and NSF Seismological Facility for the Advancement of Geoscience (SAGE). The linked map shows 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 Moekeshiwan [Lvinaya Past]. 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. |
| Large Eruptions of Moekeshiwan [Lvinaya Past] | 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). |
The Moekeshiwan caldera is seen here from the west with its NW rim at the right and the E rim on the left horizon. The 7 x 9 km caldera on southern Iturup Island formed about 9,400 years ago during one of the largest Holocene eruptions of the Kuril Islands.
