Geological Summary

A volcanic field in NE Tibet contains a number of late-Cenozoic volcanoes (Tong et al., 1988). Several Hawaiian-style volcanoes are present in this area. Bamaoqiongzong covers an area of 300 km² and contains a perfectly preserved edifice NE of the summit and a lava flow that overlies Quaternary lake deposits (Whitford-Stark, 1987). The Bamaoqiongzong area contains peralkaline phonolitic and foiditic rocks. Yongbohu contains five dacitic, trachyandesitic and andesitic vents. Qiangbaqian covers a broad area along the southern border of the Kunlun mountain range. Wei et al. (2003) did not note Holocene volcanoes in this region. A cone in the Kekexili caldera, once thought to be observed in eruption on a satellite photo in 1973, is now considered not to have been historically active (Kidd 1990, pers. comm.).

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 Unnamed. 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.
