Orange Alert – Cleveland Volcano

"The development of a lava dome in the summit crater indicates that sudden explosions of blocks and ash are possible with little or no warning. Ash clouds, if produced, could exceed 20,000 feet above sea level.
There is no real-time seismic monitoring network on Mount Cleveland and AVO is unable to track activity in real time." Quoted from the Alaska Volcano Observatory Alert.
