ARE YOU EXPERIENCING ASHFALL? We are interested in both YES and NO answers!

Reports of ashfall are important to us; we use your observations to assess the character and size of an eruption plume. We report these data to the National Weather Service so they can keep their Ashfall Advisories current. Additionally, reports of NO ashfall during an eruption with expected ashfall are also important to us. Thank you for your participation in volcano science!

Personal Information

No personally identifiable information will be distributed; all personally identifiable information will be used internally by the Alaska Volcano Observatory (AVO) and National Weather Service (NWS). AVO scientists may use some of the information that you enter in qualitative description fields in publications; you would be identified as "an observer" and your location given in general terms. Parts of some first-person accounts may be reproduced as quotations in AVO publications. Location information will only be used to generally show the location of ashfall on maps and by the NWS to update their Ashfall Advisory statements. The AVO and NWS work collaboratively to track ashfall and all personally identifiable data will be kept internal to both agencies and not distributed.

If you click the checkbox below, one of our AVO scientists may contact you to ask more in-depth questions about your report.
