Some AVO information accessed through this page may be preliminary in nature and presented prior to final review and approval by the AVO Scientist-in-Charge. This information is provided with the understanding that it is not guaranteed to be correct or complete, and conclusions drawn from such information are the sole responsibility of the user.

These are automatic computer-generated maps and have not necessarily been checked by human oversight, so they may contain errors. Further, the input data for these maps are taken directly from the community of internet users. While we make efforts to sort out unusual individual observations, the "net" product may still contain errors.

These maps are preliminary in nature and they will be updated frequently as data is supplemented by additional observations. It is important to reload your browser to see the update. Additionally, older observations will be removed from the map in an effort to keep the data display as current and near-real-time as possible.
