AVO IMPLEMENTS NEW VOLCANO HAZARD NOTIFICATIONS FOR VOLCANIC ACTIVITY
The Alaska Volcano Observatory is implementing a new format for written notices of volcanic activity.
AVO will now issue a Volcanic Activity Notice (VAN) to announce eruptions, other significant activity, and alert level and color code changes for Alaskan volcanoes. For our aviation customers, a Volcano Observatory Notification for Aviation (VONA) will be offered. Daily status reports and weekly summaries will remain largely unchanged. Information Releases will be replaced by Information Statements.
These messages will be available via an e-mail subscription service at some time in the near future. They will also be posted to our web site.
The intent of this change is to provide a clearer and more consistent statement of volcano hazard information. It is our hope that the more structured format of the VAN and VONA will enable users to more quickly find the hazard content of most interest.
We will evaluate these new message protocols over the next several months and make changes as needed.
