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

Reports of ash fall 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!
