New Volcano Numbering System ImplementedThe Volcano Hazards Program has begun using new numerical identifiers for each volcano in our area of responsibility. These numbers are assigned and maintained by the Smithsonian Institution's Global Volcanism Program (GVP). You will see these numbers in current alerts and other information products for specific volcanoes. For example, Kilauea's identifier has changed from 1302-01- to 332010.
For more information, see http://www.avo.alaska.edu/news.php?id=821, http://www.volcano.si.edu/ or contact GVP database manager Ed Venzke (VenzkeE@si.edu).
