Welcome to:

The MIVO system is a free service offered by myself, a volcanologist currently on break (note: The similarly acronymned MVO, or Monstserrat Volcano Observatory, is not affiliated with this website). The McClarren Internet Volcano Observatory is designed as an internet relay of volcanic information among scientists and lay-people. I have taken every effort to provide you with detailed information concerning various topics in volcanology and related geology while not making it unreadable to those of you who are not already experts. The McClarren Internet Volcano Observatory is not a physical place; you can not visit it if you track me down- it is a virtual domain with no physical location. You can be assured that the information provided by this website is updated and accurate. Welcome to the observatory!
