A new lava dome was discovered on the summit crater of Cleveland volcano. Volcano Observatory, Alaska has raised the aviation color code of hazard to “orange” in the area of the volcano.
Recent satellite observations have shown that the new lava dome increases and partially fills the summit crater. A new dome is about 70 m in diameter and similar in size to the previous lava domes. When a lava dome increases, sometimes it is an explosive activity. Growth of the dome increases the potential of the explosive activity of Cleveland.
