alaska-volcanoALASKA – Researchers detected two small explosions at Cleveland Volcano on Monday afternoon and early Tuesday morning, according to the Alaska Volcano Observatory. The first occurred a little after 5 p.m. Monday and the second at 1:35 a.m. Tuesday. The AVO said the explosions were brief, and were detected by infrasound and lightning alarms. A small ash cloud — the presence of which was confirmed by satellite — was estimated to be drifting at an altitude of about 16,000 feet above sea level. “These explosions are typical of eruptive activity of Cleveland over the past few years,” reported AVO. “There may be a heightened chance of additional ash emissions in the coming weeks. Because these explosions were brief and there is no sign of ongoing eruption, Cleveland remains at Volcano Alert Level/Aviation Color Code YELLOW/ADVISORY.” The 5,676-foot peak [3], also known as Mount Cleveland, is in Alaska’s Aleutian Islands and has erupted numerous times in recent years. Its alert level was briefly raised to orange for a week in January, before being lowered to yellow again Jan. 10.  Extinction Protocol
