This is based on the 2005 edition of the WOVO Directory. Member observatories are listed in alphabetical order: the numbering scheme of the Catalogue of Active Volcanoes of the World, and of Simkin and Siebert (1994) Volcanoes of the World is shown when hovering overthe links. The numbering scheme is shown in more detail at http://www.volcano.si.edu/.
As with any directory, information changes. This directory contains the latest information we have from each observatory. Each entry shows the date of latest update or correction. Any user noticing an error should please send the correction to: wovo.iavceigmail.com
We will try to keep this information current but we cannot guarantee accuracy or currency. Any user that might need to contact a member observatory under emergency circumstances should confirm the contact information independently.
