How to collect an ash sample for 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.

Before an eruption
Read the USGS Ashfall Preparedness "Before an eruption" website

2009-01-02 13:48:39 - Weekly Update

A short-lived but explosive ash emission occurred this morning to about 6 km (20,000 ft) altitude. The plume was first observed in a satellite image obtained at 1645 UTC (7:45 AKST)and was visible in subsequent images for several hours. The plume drifted about 240 km (150 mi) east-southeast, but dispersed rapidly and presently can no longer be detected. Satellite views of the volcano have been obscured by clouds most of the week. A small thermal anomaly was observed on Dec. 28, but has not been seen since. No other reports of activity have been received. Cleveland is not seismically monitored; satellite data and pilot reports are the primary source of information.

NOAA ARL Ash Trajectory Forecasts

Click on a picture for a larger image.

These graphics depict a simulation of the direction and speed of potential ash cloud motion from Cleveland. 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).

Model output by NOAA ARL, please see http://www.arl.noaa.gov/ready/traj_alaska.html for more information.

December 2008 Updates

Friday, December 26, 2008 1:52 01:52:28 PM AKST

AVO raised the aviation color code to Yellow and the alert level to Advisory at Cleveland on December 24 based on a thermal anomaly near the summit seen in satellite data the previous night. Clouds have obscured the volcano from satellite since then and no further observations have been recorded. Such thermal observations in the past have many times, but not always, preceded eruptive activity that has sent ash to altitudes of more than 20,000 ft above sea level and in 2001 as high as 39,000 ft. Eruptions in July 2008 produced ash plumes exceeding 25,000 ft. Cleveland volcano is not seismically monitored; satellite images and pilot reports are the primary source of information.

AVO is raising the aviation color code to Yellow and the alert level to Advisory. Satellite images acquired last night show a persistent thermal anomaly near the summit of Cleveland volcano. Such observations in the past have many times, but not always, preceded eruptive activity that has sent ash to altitudes of more than 20,000 ft above sea level and in 2001 as high as 39,000 ft. Eruptions in July 2008 produced ash plumes exceeding 25,000 ft. Cleveland volcano is not seismically monitored; satellite images and pilot reports are the primary source of information.
