what type of volcano is langila

The larger explosions rose several hundred meters above the crater rim, dropping ash on the downwind (N-NW) side of the volcano. Vulcanian eruptions continued at Langila's Crater 2 during 21-27 November, with a slight increase in the level of activity compared to the previous week. RVO reported that emission of ash plumes from Langila's Crater 2 continued during 10 June-3 July and were occasionally forceful. "From the 8th until the end of the month, Crater 2 released white emissions in small to moderate quantities. "Activity increased somewhat in June as Vulcanian explosions became more frequent. and drifted over 45 km W. Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that during 21-24 December ash plumes from Langila rose to an altitude of 2.4 km (8,000 ft) a.s.l. During October varying amounts of white fume were emitted from Crater 3. Ashfall NW of the volcano (in the Kilenge area) was reported on 11 April. Crater 2 emitted thin to thick white vapor throughout September, with an occasional ash component. Based on analyses of satellite imagery, the Darwin VAAC reported that on 12 September an ash plume from Langila rose to an altitude of 3 km (10,000 ft) a.s.l. Glows of variable intensity were seen on most nights during the first three weeks. There were no reports of incandescence or sounds from the summit, and seismicity was at a very low level.". A changing weak-to-bright glow accompanied by projections of glowing lava fragments were visible on the nights of 22-23 and 28 February, and 1-2, and 6 March. There was an unconfirmed report of a new lava flow from Crater 3 on the 28th. Seismicity showed a moderate level of activity with 1-46 recorded explosion events/day.". Mild Vulcanian eruptions during July-October 2000. A weak incandescent glow was seen on 22 and 28 April. Vulcanian eruption columns rose to about 300 m on 16 May, and 7 km on 17 May. Explosions occurred at rates of up to about 20 per day in February. Ashfalls were experienced in inhabited areas about 10 km N and NW of the volcano during most of the first half of the month. Ashfalls to 10 km from the source were common. Occasional roaring and rumbling noises were heard. However, the volume of emission increased to moderate or large during the first 10 days of February, the time of the activity buildup at Crater 2. . Information Contacts: Patrice de Saint-Ours, RVO. Activity at Crater 3 was subdued, consisting usually of weak emissions of white and rarely grey vapour, and occasional emissions of blue vapour. They blew to the SE, resulting in light ashfall. "Activity at Crater 2 was at a low level 1-19 July with emissions of weak white vapour, occasionally blue or containing ash. Ongoing eruptions lead to detectable ashfalls 10-15 km away. Crater 3 released weak, thin white and blue vapours. "Activity at Crater 2 . Moderate activity took place at Langila during January 2006, including continuous ash fall, rumbling, and weak emissions of lava fragments. "Crater 2 released weak to moderate white vapour emissions plus occasional grey ash and blue vapours. Heights of Vulcanian explosion columns above Crater 2 at Langila, April 1983. RVO reported that emission of ash and white vapor plumes from Langila's Crater 2 continued during 1 August-30 September. The activity was marked by intermittent audible explosions. and drifted N and NW. It is located 11 km south of Cape Gloucester. A brief aerial view of the interior of Crater 2 on 14 August indicated that it remains funnel-shaped, with several benches. Information Contacts: R.J.S. "Moderate eruptive activity continued during May. Seismic activity was reportedly unchanged. Frequent tephra emission; tremor declines. During the first week of July, ash emissions blown down the volcano's flanks by strong winds occasionally obscured the active vent. These clouds rose several hundred meters above the rim before being blown to the N, NW, and SE and producing fine ashfalls. This activity was accompanied by nearly continuous low roaring sounds. continued unabated in December. During July, Crater 2 continued to release weak-to-moderate white vapor with occasional pale-gray ash. and drifted predominantly N and NE. and dissipated. ", "Eruptive activity continued apparently without change during June. Frequent small brief seismic events began to be recorded at mid-month. 07/1973 (CSLP 96-73) Lava emission from Crater 3 in mid-July, 02/1974 (CSLP 96-73) Large explosion from Crater 2 on 15 February, 05/1978 (SEAN 03:05) New mild Strombolian eruption, 09/1978 (SEAN 03:09) Vulcanian activity;

Weak fumarolic vapor was released from Crater 3. Steady weak night glows were occasionally observed.". After Vulcanian activity in the latter part of 2009, activity at Langila subsided, with infrequent activity until 2016, when activity increased somewhat through May 2018 (BGVN 34:11, 35:02, 42:01, and 42:09). Incandescent tephra ejections or crater glow were common during the first half of the month, but only occasionally observed later in November. Seismicity was low during this period. Weak roaring noises were heard on 1 July, but glow was absent at night. An extensive lava field extends toward the coast on the north and northeast side. On 13 and 14 February, eruptive activity at Langila's Crater 2 consisted of continuous emissions of gray ash plumes. Larger events were recorded 8-17 February. The seismograph remained non-operational throughout the entire reporting period. Crater 3 remained quiet. ", Occasional ash emission; explosion sounds; glow, "Activity returned to a low level in October . Ashfalls were mainly in uninhabited areas SE of the volcano, but on one occasion there was a fine ashfall ~10 km to the NW. Weak steady glow was observed on the 6th and the 9th. 1). It is the world’s largest humanitarian organization and its millions of volunteers are active in over 181 countries. "Activity at Crater 2 consisted mainly of weak-moderate emissions of white vapour, with rare ash emissions. A rectangular, 2.5-km-long crater is breached widely to the SE; Langila was constructed NE of the breached crater of Talawe. The following night, Strombolian ejections reached 100 m above the crater rim. "Crater 3 activity may have declined during the month. Aust Bur Min Resour Geol Geophys Rec, 1971/14: 1-34. Explosions build to 6-day Strombolian-Vulcanian event. Activity remained at a low level in April. "The daily number of Vulcanian explosions from Crater 3 reached its maximum level of >30 between the 15th and 19th, coinciding with the absence of night glow at both craters (figure 3). Based on analyses of satellite imagery and wind-model data, the Darwin VAAC reported that on 23 September an ash plume from Langila rose to an altitude of 2.7 km (9,000 ft) a.s.l.
