USGS Seeks Approval to Keep Tracking Ash Falls – Data Continues
Published Date: 5/7/2026
Notice
Summary
The U.S. Geological Survey wants to keep collecting info about ash fall events to help track and understand volcanic activity. They’re asking the public to comment by June 8, 2026, but no one has raised concerns so far. This renewal won’t cost extra or add paperwork hassles, just keeps the data flowing smoothly for safety and science.

Public Reports Improve Ashfall Warnings
USGS will use real-time and retrospective ashfall reports from the public to correct or refine ash fall forecasts, improve ashfall models, and make ash-fall warning messages and Volcanic Activity Notifications more accurate. These reports help AVO staff and emergency managers track eruption clouds and forward summarized information to the public and emergency agencies.
Voluntary Ash-Report Collection Continues
The USGS will continue asking the public, local governments, and emergency managers to report volcanic ashfall using a web form. About 250 people are expected to respond each year, typically 1–6 times per year, with each response taking about 5 minutes (total 21 hours annually); responding is voluntary.
Report Details Publicly Shown for 24 Hours
Ashfall reports entered into the USGS system will be shown publicly on a dynamic map for a period of 24 hours and will include key fields such as date/time, location, whether ash was observed, name of observer, and contact information. AVO staff may use the provided contact information to follow up with reporters.
