Volcano Activity Notifications


About Color Codes & Alert Levels

In 2008, AVO switched to a new program to release reports. Reports prior to 2008 have been archived in a separate system. Due to the way these reports have been stored, archived reports cannot by searched by color code, alert level, and report type. If you would like to include archived reports in your search, check the box below.
