During 13-24 May, a fumarolic plume rose 50-100 m above the volcano and drifted 1-5 km S and SE. in mid-March 1993, after a short period of repose, when explosions in the central crater sent an ash-and-gas cloud 1-2 km above the summit. There were 5-minute intervals between explosions. KVERT maintained a hazard status of GREEN as of 10 May 2001. KVERT reported that a Strombolian eruption at Klyuchevskoy continued during 23-30 September. According to a news article, lava flowed from a fissure during 8-9 July. Hypocenters of earthquakes recorded in late May were concentrated at two levels: near the summit crater and at depths of 25-30 km. Strombolian activity continued and several lava flows continued to effuse onto the W, SW, and SE flanks. (Gas-and-steam activity was moderate-to-strong in late February.) The Aviation Color Code level was raised to Orange. Based on analyses of satellite imagery and information from KEMSD, the Tokyo VAAC reported that on 17 August an eruption from Kliuchevskoi produced a plume that rose to an altitude of 5.2 km (17,000 ft) a.s.l. The Klyuchevskaya Sopka on Kamchatka, a volcanic peninsula in Russia's Far East, is the tallest volcano in Eurasia at 4,750 metres (15,580 feet) and one of the largest active volcanoes in the world. Gas-and-steam plumes rose to ~1 km above the volcano. A VONA issued at 0242 on 17 November 2013 indicated that web camera assessments revealed strombolian eruptions with strong gas and steam; an ash plume rose to 7 km altitude and blew 160 km E. The four-step Aviation Color Code (low to high, Green, Yellow, Orange, and Red) rose to Orange. The explosive-effusive eruption continued from May through September 2016. But during 3-9 March, seismicity at the volcano increased again and the hazard level was raised again to Yellow. Fumarolic activity was seen during last days of April (figure 11). No fumarolic plumes were seen on 30 September, 2, 3, 6, 11, or 16 October. Continuous volcanic tremor, with a maximum amplitude of 6.3 µm, was recorded at distances of 11 km from the volcano. Seismicity decreased during the following days and on 23 November KVERT decreased the Color Code to Green. The Tokyo VAAC reported that on 2 January ash plumes were continuously observed on satellite imagery. Please note comments are moderated before publication. Activity has included lava flows, a growing cinder cone, thermal anomalies, gas-and-steam plumes, and ash explosions. Clouds obscured the volcano at other times. On 1, 14, 15, 18, and 19 October a fumarolic plume was observed during the daylight hours rising 50 m above the summit. Gas-and-steam explosions with ash-poor plumes that rose up to 200 m above the crater. Based on information from the Yelizovo Airport (UHPP) and satellite imagery, the Tokyo VAAC reported that during 18 and 22-23 January ash plumes rose to altitudes of 7-10 km and drifted N and NE. Strombolian bursts rose 500-1,000 m (1,600- 3,300 ft) above the summit crater. Background seismicity was concentrated near the summit crater and at depths of 25-30 km. IMO has decided that the eruption began at 20:45. The lava flow ended at about 3,700 m elevation and spalled off incandescent material, descending an additional 350 m. The Aviation Color Code remined at Orange (the second highest level on a four-color scale). IAVCEI 1990 Internatl Volc Cong, Mainz, Abs, (unpaginated). On the next image, at 1233 on 22 December, the hot spot was accompanied by a diffuse plume that extended about 350 km SE. Precursors to the 17 August eruption included elevated seismicity and ash visible in fumarolic emissions. According to video data and visual observations on 27 and 31 May, there was Strombolian and Vulcanian activity at the summit crater, lava flows, and phreatic bursts on the NW flank from where lava interacted with ice. A strong thermal anomaly was seen in satellite imagery at night. The Level of Concern Color Code remained at Orange. On 3 December a gas-and-steam plume rose ~1.3 km above the crater and drifted N and NE. Strong explosions began at 0315 on 15 May, and generated ash plumes that rose as high as 10.5 km (34,400 ft) a.s.l. Lava flows on the NW and SW slopes of the volcano remained active, and mudflows were noted on the N slope. During 28 November-10 December, Strombolian activity ejected bombs 500 m above the crater and lava effusion on the NW flank continued. The next day an eruption seen in satellite imagery produced an ash plume that rose to an altitude of 10.1 km (33,000 ft) a.s.l. | February Satellite images showed an intense daily thermal anomaly over the volcano. Two large explosions on 5 February sent ash plumes that drifted ENE to 8.2 and 9.1 km altitude (figure 62). Because of the increase in activity, the alert status was changed to Yellow, meaning more significant eruptions may occur. Melekestsev I V, Braitseva O A, Ponomareva V V, 1989. Ash plumes drifted 55 km ENE. An ash plume rose to 4.5 km (14,800 ft) a.s.l. Ashfall was reported in Klyuchi, 30 km NNE on 11 June. While book on volcano geodesy.

This advertising is managed by, and targeted through, Google Adsense. Earthquakes, both at 30 km and shallow depths, continued to register. Satellite imagery analyses showed a thermal anomaly over the volcano and ash plumes that drifted 480 km SE. During 4-14 July the anomaly continued to decline and only weak fumarolic activity was visible. Clouds frequently obscured the volcano during December. On 20 July, the ACC was lowered to Green. Aftershocks of this event (M <= ~ 4.2) continued to occur through 19 April. Gas-and-steam plumes rose 1,300 m above crater and extended 10 km NE. Volcanic eruption continues at the present time. Nine such events that week were followed by totals of 4, 22, 48, and 43 per week over the next month. Fumarolic activity was observed during 16-18 November; cloud cover prevented observations on the other days. Found inside â Page 110The advance of the Erman Glacier was initiated in 1945 during the eruption of the Klyuchevskoy volcano after a volcanic-glacial landslide along the ... Counts increased to 75 for the week of 15-21 November, 80 during 22-28 November, and 130 for the week ending on 5 December. | March At 0559 on 19 October ash plumes observed in satellite images drifted 630 km SE at altitudes of 8-9 km (26,200-29,500 ft) a.s.l.

The highest rising ash-and-gas plume reached ~1.5 km above the volcano on 10 September. Weak intermittent volcanic tremor and fumarolic activity continued to be detected. The deposits were not accompanied by visually or seismically detected explosions. Fumarolic activity was noted during 10-11 and 13-16 October. A comprehensive and authoritative text on the formation and evolution of planetary atmospheres, for graduate-level students and researchers. Its height is changing from 4750 to 4850 m and is over the sea level. Information about more recently started eruptions can be ⦠A plume rose 300-500 m over the summit. These thermal anomalies were also recorded by the Sentinel-2 MODIS Thermal Volcanic Activity data on a MIROVA graph, showing a strong cluster during June to early July, followed by a sharp decrease and then a hiatus in activity (figure 47). Lava flows extend from this cone down the NW flank. Based on atmospheric profiles, ash plumes rose to estimated altitudes of 4.5-9.5 km (14,800-31,200 ft) a.s.l. IV noted an increase in activity . and drifted 30 km SE. | July The Level of Concern Color Code was raised to Orange. In October 1994, Klyuchevskoy Volcano in northern Kamchatka erupted explosively, sending a column of volcanic ash more than 9 miles (15 km) into the air. KVERT reported that during 15-22 January seismic activity from Kliuchevskoi was above background levels and lava continued to flow down the NW flank. Two days later at 0216, two weak plumes seemed to be emerging from the area, perhaps one from Kliuchevskoi and one from Bezymianny. The Aviation Color Code was raised to Orange (the second highest level on a four-color scale) on 8 October. According to analysis of a satellite image at 1825 on 3 February the plume extended 40 km SSE and contained a large amount of water or ice. Table 6. | February The eruption appeared to reach its maximum intensity between 0600 and 1630. Another ash plume the next day rose to the same altitude and extended 388 km NE. Klyuchevskoy seems to always be erupting. KVERT reported that ash plumes from Klyuchevskoy were identified in satellite images drifting 270 km SE and NW during 5-6 and 10-11 May, respectively. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Satellite imagery analyses showed a large and intense daily thermal anomaly over the volcano. Spasmodic tremor was recorded the entire week. Satellite images detected daily weak thermal anomalies over the summit and the SW flank. On 15 March two lava flows were observed on the NW slope. Weak intermediate-depth earthquakes decreased from 2 to 8 September, averaging only 1-4 events/day. On 8 March, a steam-and-gas plume rose 1,000 m above the volcano extending 5 km to the NW. Gas-and-steam plumes containing a small amount of ash were noted during 13-18 May. Ash plumes were seen rising to altitudes of 6.5-7 km (21,300-23,000 ft) a.s.l. The ash column was estimated at 15-20 km altitude and extended >100 km SE. They reported that only a small flow emerged from the W foot of the cone and flowed N (figure 71). Kliuchevskoi was last reported on in April 2004 (BGVN 29:04) and this report covers the interval through 31 March 2005. Seismicity returned to background levels on 13 March and the hazard level was reduced to Green. Also, volcanic tremor remained at the previous level (0.7-1.0 mcm/s) and shallow volcanic earthquakes registered. Heavy snowfall impeded observation of the crater, but the staff of the local IVP station were monitoring the volcano with instruments. . Weak fumarolic activity in the crater continued through 6 November, with seismicity near background levels.

Simultaneous summit and flank eruptions at Kliuchevskoi 6-9 April were accompanied by a swarm of M 2.5 earthquakes. Eruptions: Eruption styles: The Global Volcanism Program puts it this way (emphasis added): . Doubik, Institute of Volcanology, Petropavlovsk. On 16 November, an ash plume extended up to 85 km NW. Increased seismicity on 19 June was followed by plumes and ashfall in Kozyrevsk village. Satellite images showed a weak thermal anomaly during 16-17 and 23 April; a gas plume containing a small amount of ash drifted 147 km E on 21 April. Additional explosions during 27-30 March generated ash plumes to an altitude of 7 km that drifted 300 km in multiple directions. An ash plume on 29 May 2011 that rose to an altitude of 5 km prompted KVERT to raise the Aviation Color Code to Orange. Ash explosions reached ~1 km above the volcano each day of the report week, except 6 July. Within the summit crater, eruptive outbursts occurred throughout the day. Gas-and-steam plumes containing a small amount of ash were noted during 6 and 8-12 May. On 22 May, KVERT described activity as weak. Gas-and-steam columns rising from two apertures at the summit reached 2,500 m above the crater on 10 October and 800 m on 14 October. Ash plumes occasionally rose to an altitude of 5.5 km (18,000 ft) a.s.l. Satellite imagery revealed a weak thermal anomaly over the volcano. Lava effusion on the NW flank continued and Strombolian activity was noted during 21-25 December. Satellite imagery showed gas-and-ash plumes drifting 430 km N and NE during 26-29 November and a weak thermal anomaly over the crater on 26, 28, and 29 November. Satellite imagery revealed a large daily thermal anomaly at the volcano. | September From mid-February through mid-August 2018 moderate to weak gas and steam plumes were observed (figure 29), but no ash plumes were reported after 15 June 2018 (figure 29). On 28 June, seismicity increased and indicated that an ash plume rose to an altitude of 9 km (30,000 ft) a.s.l. At the end of the report period, seismicity was slightly above background with a small gas-and-steam plume visible from nearby villages. On 15 August, a new explosive eruption began, with renewed Strombolian activity. Strombolian activity was observed on 1 and 2 December. Seismicity was above background levels at Kliuchevskoi during 4-12 July. On 11-12 June webcam data showed explosions that sent ash up to a maximum altitude of 6 km, with the resulting ash plume extending about 200 km WNW. These were presumably a result of a solid medium in those regions under the influence of continuously changing stress fields. during 27-28 January. Strong summit explosions cause ashfalls 375 km away; SE flank lava fountains feed lava flow. Video recordings captured Strombolian activity and strong gas-and-steam events. On 25 March the Aviation Color Code was lowered to Yellow. and drifted 340 km mainly E. The Kamchatka Volcanological Station field team visited the area on 24 December to do work on field stations. and drifted N.

On 12 June ash plumes from Klyuchevskoy rose to an altitude of 5 km (16,400 ft) a.s.l. On 19 December, KVERT reported that the Level of Concern Color Code for Kliuchevskoi was raised from Green to Yellow due to a slight increase in seismicity above background levels. based on atmospheric profiles. A plume released on 8 May extended 30 km to the S and at 1230 on 9 May a plume rose 2,000 m above the crater. The ACC was briefly raised to Orange before again being set at Yellow on 12 May. Kliuchevskoi remained at Concern Color Code Orange. KVERT reported that seismic activity at Kliuchevskoi was at background levels during 13-20 July. More than 100 flank eruptions have occurred during the past roughly 3000 years, with most lateral craters and cones occurring along radial fissures between the unconfined NE-to-SE flanks of the conical volcano between 500 m and 3600 m elevation. Gas-and-steam plumes rose to a maximum height of ~1 km above the crater. Klyuchevskoy, Russia’s highest and most active volcano in the far eastern Kamchatka peninsula, ejected a six-metres high column of ash. During 16-19 November explosions recorded in satellite and video data showed ash plumes rising to 7.5 km altitude and drifting as far as 108 km to the NE, E, SE, and S (figure 50). Seismicity was above background levels at Kliuchevskoi during 12-19 September, with 2-6 earthquakes between M 1.7 and 2.2 occurring. On 27 July at 2200, the gas-and-ash plume was as high as 5 km above the crater, extending to the S for an unknown distance. A lava flow continued to advance down the Apakhonchich drainage on the SE flank. and drifted 120 km SE. During the week ending 7 November tremor took place and earthquakes remained elevated. Gas-and-steam plumes that rose to ~ 1 km above the volcano's crater drifted SW on 29 January and NW on 31 January. An ash plume drifted 22 km SE on 2 May. During 7-8 October activity intensified and was characterized by strong explosions, collapses of the sides of the drainage, strong thermal anomalies, and ash plumes that extended over 200 km SE from the crater; the lava flow remained active and continued to descend the SE flank.

Klyuchevskoy has been active for many decades, alternating between eruptive and less active periods. Gas-and-steam plumes with some ash drifted 465 km SE and E on 29 and 31 May, and 1 June. on 24 November and weak fumarolic activity was observed on several days. Since there were no indications that an eruption was imminent at Kliuchevskoi, KVERT reduced the Concern Color Code from Yellow to Green on 4 November. The magnitude of seismic tremor significantly decreased at 0520 on 9 March, likely signifying the end of the explosive eruption. and drifted almost 60 km WNW. Taller plumes. and drifted N. KVERT reported that during 3-10 December seismic activity at Kliuchevskoi was slightly above background levels. According to KVERT, activity at Kliuchevskoi decreased in late 2012 (around the same time the Tolbachik eruption began). Another ash plume the next day that rose to as high as 7.5 km altitude and drifted 75 km SW prompted an Orange ACC status. A satellite image from 9 March showed that the S-flank lava flow was about 1.3 km long. "Bursting" sounds from the volcano were heard in Klyuchi, about 30 km to the NE. The Aviation Color Code was raised to Orange. and drifted about 300 km E and W during 16-17 and 22 June. Ivanov, B.V., Chirkov, A.M., Dubik, Yu.
