The growing lava dome in the Cleveland Volcano increases the possibility of an explosive event.If it does erupt it can have ash clouds over 20,000 ft above sea level. If this does happen without warning it may go undeteced in sattalite images for hours.the Cleveland Volcano is 5,676 ft and is located at the Aleutain Islands in Alaska.On September 22 the lava dome was 65 ft below the crater rim. It can reach the top in the next couple of weeks but that doesn't mean it will explode.
