|(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)|
|(3) Volcano:||Cleveland (VNUM #311240)|
|(4) Current Color Code:||UNASSIGNED|
|(5) Previous Color Code:||YELLOW|
|(6) Source:||Alaska Volcano Observatory|
|(7) Notice Number:||2010/A7|
|(8) Volcano Location:||N 52 deg 49 min W 169 deg 56 min|
|(10) Summit Elevation:||5676 ft (1730 m)|
|(11) Volcanic Activity Summary:||Several clear-weather satellite views of Cleveland from September 7 and 8 reveal no thermal anomaly nor recent deposits. The last observed thermal anomaly was on September 1. AVO is therefore moving the volcano alert level/aviation color code from Advisory/Yellow to UNASSIGNED.
Without a real-time seismic network at Cleveland, AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions with ash clouds that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery for hours. Low-level ash emissions at Cleveland occur frequently and do not necessarily mean a larger eruption is imminent. AVO continues to monitor the volcano using satellite imagery.
|(12) Volcanic cloud height:||Unknown|
|(13) Other volcanic cloud information:||Unknown|
