Cleveland has been steaming fairly continuously since at least 1982, when he began flying regularly from Dutch Harbor (Unalaska Island) to Atka (Atka Island). On 22 February, satellite imagery detected a low-level ash plume that drifted about 300 km SE. The Alaska Volcano Observatory has raised the alert level for Mount Cleveland, a 1730 m stratovolcano (cone-shaped volcano made up of layers of ash and lava), located on Chuginadak Island, roughly 500 km southeast of Anchorage in the Aleutian Island Chain, following an eruption on Monday 1 June 2020. Alaska's volcanoes, northern link in the ring of fire. This level of activity -accompanied by persistent thermal anomalies - occurred throughout the spring and early summer. In 1944 it produced the only known fatality from an Aleutian eruption. NXT ADVISORY: WILL BE ISSUED BY 20200602/1426Z JAM/CML JUN 2020 AAWU. A vigorous steam plume was observed by pilots on 29 April and by AVO observers on 10 May. As of late January 2010, further activity at Cleveland was absent and no further reports were issued. Minor vapor and diffuse ash emissions inside the crater were noted. The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange. No current seismic information was available because Cleveland does not have a real-time seismic network. Cloud cover up to 9.1 km (30,000 ft) a.s.l. Ten volcanoes with super-eruption potential: Part III . AVO raised the Level of Concern Color Code to Orange and the Volcano Alert Level to Watch. in satellite data. at about 0235, Heyden observed a crater ~60 m in diameter on the upper ESE flank. This report covers activity during February-July 2020 using information primarily from the Alaska Volcano Observatory (AVO) and satellite data. Surface temperatures of the cooling lava measured by the crew were in the range of 550-600°C. During the week of 25-31 July 2011 elevated but weak thermal anomalies were observed in satellite images of during periods of clear weather. AVO reported that cloudy conditions at Cleveland mostly prevented observations during 26-28 June. Residents in Nikolski (75 km E) reported hearing the explosion. Some energetic eruptions were also accompanied by dome destruction and hot lahars that descended the flanks. Satellite data suggested a maximum cloud height of ~1 km (3,500 ft) a.s.l. 2005 Volcanic activity in Alaska, Kamchatka, and the Kurile Islands: Summary of events and response of the Alaska Volcano Observatory: U.S. Geological Survey Scientific Investigations Report 2007-5269, 94 p., available at Cleveland volcano (Aleutian Islands, Alaska): AVO weekly update . The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange. The presence of a flow over the active vent increases the chances of an explosion, so AVO raised the Aviation Color Code to Orange and the Volcano Alert Level to Watch. The webcam periodically recorded steam emissions. Since the 19 March eruption there have been no reports of significant activity from either pilots, residents, or satellite remote sensors. A minor amount of ash was possibly generated by the explosion, but nothing was detected in satellite data and AVO received no reports of ash emissions from local observers or passing pilots. Niveau actuel d’alerte volcanique: AVIS AVO downgraded the level of concern color code for Cleveland from Red to Orange on 7 February 2006 at 1655 hours. AVO reported that cloudy conditions at Cleveland often prevented observations during 4-9 July. AVO raised the Level of Concern Color Code to Orange and the Volcano Alert Level to Watch. The Aviation Color Code was lowered to Yellow and the Volcano Alert Level was lowered to Advisory. and drifted S. Satellite images showed block-and-ash deposits extending for up to 1 km down the S flank. AVO reported that during 22-28 November no significant activity at Cleveland was visible in cloudy to partly cloudy satellite images, and no activity was detected by seismic or infrasound sensors. No evidence of an eruption cloud was detected above the weather cloud present at 8.5 km altitude, and no ashfall was reported in Nikolski. On 15 February, a minor explosion from Cleveland produced a small, diffuse ash plume that rose to an altitude of below 3 km and drifted NW. A small explosion occurred at 2203 on 6 August; no ash emissions were observed in satellite or webcam images. The Volcanic Alert Level remained at Advisory and the Aviation Color Code remained at Yellow. The Volcano Alert Level remained at Advisory and the Aviation Color Code remained at Yellow. Fresh lava within the summit crater was last detected in images in early May. Satellite views were obscured by clouds, though a dusting of ash on the upper flanks was noted by a nearby field crew and recorded by the webcam later in the day. En raison de cette augmentation d’activité, l’Alaska Volcano Observatory a relevé le code de couleur de l’aviation pour le volcan Cleveland à ORANGE et le niveau d’alerte du volcan à ATTENTION le lundi 1er juin. Minor steaming was noted on 8 February. A pilot reported that the altitude of the plume was in excess of 9.1 km (30,000 ft) a.s.l. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch. A small explosion at Cleveland was recorded by the seismic network at 1155 on 8 December. Coats R R, 1950. | November Details of the 2013 activity are provided in Dixon et al. It seemingly generated a diffuse ash plume, an event detected a few days later in satellite imagery (figure 7). The Level of Concern Color Code remained at Orange and the Volcano Alert Level remained at Watch. La vibration sismique du volcan s’est maintenue entre 18 et 21 unités RSAM, en moyenne par jour, ceci étant une plage normale. The ash cloud was located E of the volcano and ~150 km ESE of Dutch Harbor at 0900. Thermal anomalies were identified in satellite data during 15-16 February, and possibly on 17 February. AVO raised the Volcanic Alert Level for Cleveland from Advisory to Watch and the Aviation Color Code from Yellow to Orange on 20 July. At 1700, an image showed the detached ash plume 130 km SW of Cleveland. The only recent alerts during that interval were during the period of 22-29 July. Satellite observations indicated that a new lava dome had been extruded and was partially filling the summit crater. The Volcano Alert Level was raised to Watch and the Aviation Color Code was raised to Orange. On 12 June, steam emissions were observed. | July Minor degassing from the summit was seen in satellite and webcam images during 20-21 August. Catalogue of the historically active volcanoes of Alaska. The pilot report suggested that the cloud altitude was 10 km (35,000 ft) a.s.l. Neither eruptive activity nor thermal anomalies have been observed at Cleveland during the previous 6 weeks. On 3 November AVO lowered the Volcano Alert Level to Advisory and the Aviation Color Code to Yellow because satellite observations indicated no significant change in the size of the lava dome, and no explosive activity or ash emissions had been reported. On 16 October, satellite imagery revealed moderately elevated surface temperatures, and the webcam provided views of a small steam plume. Mount Cleveland is arguably the most active volcano in North America for at least the last 20 years. Henning R A, Rosenthal C H, Olds B, Reading E (eds), 1976. AVO raised the Volcano Alert Level to Watch and the Aviation Color Code to Orange. 3.
