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 Robinson Crusoe. 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 Robinson Crusoe | 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). |
An eruption plume (upper left) rises on February 20, 1835 from a submarine volcano in Bahía Cumberland off Punta Bacalao on Robinson Crusoe (Mas a Tierra) Island. The sketch was made by Sutcliffe (1939), the island's governor; during the eruption flames were reported that lit up the island. Robinson Crusoe, in the central part of the Juan Fernandez Island group, is composed of four overlapping shield volcanoes with calderas breached to the NE. The SW part of the basaltic island consists of smaller altered cones.
