More About GVMID

is a Database of volcano monitoring infrastructure which contains information about monitoring networks, stations, and instruments. The instruments types include those that record changes in seismicity, ground deformation, gas emission, thermal and other parameters that manifested volcanic activities.

The database is created following the structure and format as described in the WOVOdat 1.0 report of Venezky and Newhall (USGS Openfile report 2007-1117), updated in WOVOdat 2.0 (here). The Data in GVMID is organized in a MySQL hierarchical relational database management system where all available data in a specific volcano will be linked through “volcano” as the parent table.

Nearly all data in GVMID are time-stamped and georeferenced, so that they can be studied in both space and time. The data will be further updated by various contributors through time. Please note that the data stored and displayed in GVMID does not reflect the current or real-time operational volcano monitoring infrastructure.
