GVP 2021 Eruption
Figure 2.01. Map Locations for young volcanoes.
Locations of volcanoes that erupted during the Holocene or Pleistocene based on data from the Global Volcanism Program (GVP) dataset of the Smithsonian Institution (Venzke, 2013). Zoom and pan with your mouse or mousepad to look more closely at seleted areas. For the Mercator projection map, zoom out to see the volcanoes at high latitudes. Or select another map projection from the pulldown list. As you mouseover a datapoint, the volcano name, erupted rock type, and tectonic setting should appear. Different colors are used for different rock types. Use the slider in the header to shift the center of the map; clicking on it works better than sliding because of the computation time.
To view volcanoes for other age ranges, particular rock types, or by tectonic setting, choose from among the Smithsonian DataSets from the pull down "DataSet" list. Press the "Show Plate Boundaries" button to see tectonic plates.
If you wish to show other volcanoes on this global map, you can upload your own data from a comma separated variable (.csv) file with column headers: Volcano, Rock Type, Latitude, Longitude, Rock Name, ColorValue, and Setting. Put these data for individual volcanoes in rows.
