How to collect an ash sample for AVO

Report ashfall to AVO

Please report ashfall to us by email or phone (786-7497). We'd like to know your location, time, if the fall is light or heavy, and the current weather. It would help us if you collect a sample for us. Here are instructions.

These graphics depict a simulation of the direction and speed of potential ash cloud motion from Redoubt. IF a significant ash cloud were generated by the current eruption. It does not mean that such an ash cloud has been produced. These models are run every 6 hours independent of the current eruptive state of the volcano. Each colored line indicates the direction a cloud would travel at different altitudes (see key below map plot).

Here is how to convert from UTC to AKDT (Alaska Daylight Time):

0000 UTC= 4:00 PM AKDT on the previous day as UTC
0600 UTC= 10:00 PM AKDT on the previous day as UTC
1200 UTC= 4:00 AM AKDT on the same day as UTC
1800 UTC= 10:00 AM AKDT on the same day as UTC
