Geological Summary

Bliznets is a Quaternary basaltic stratovolcano on the crest of the central Sredinny Range SW of Kebeney volcano. Cinder cones were constructed on the E flank, and a group of cones and associated lava flows cover the northern side of the volcano. Early geological studies in the Sredinny Range (Ogorodov et al., 1972) assigned Holocene ages based on morphology, but later work noted that these volcanoes appear younger because they have less tephra cover than those in eastern Kamchatka. Researchers such as Pevzner (2006) and Ponomareva et al. (2007) do not consider this volcano to be Holocene.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Bliznets. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Bliznets page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions.

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.

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 Bliznets. 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.
