Manam volcano news and eruption updates (New Guinea): Manam Volcano Volcanic Ash Advisory: MINOR DISCRETE VA OBS TO FL100 MOV SW AT 06/1340Z to 10000 ft (3000 m) Thursday Aug 06, 2020 14:15 PM | AUTEUR : VN Weak ash emissions were observed drifting N for the next two days along with an IR anomaly at the summit. The Darwin VAAC reported a discrete emission observed in satellite imagery on 8 November that rose to 4.6 km altitude and drifted WNW, although ground observers confirmed that no eruption took place; emissions were only steam and gas. Papua New Guinea's Manam volcano released a thin, faint plume on June 16, 2010, as clouds clustered at the volcano's summit.
The Darwin VAAC reported a discrete emission observed in satellite imagery on 8 November that rose to 4.6 km altitude and drifted WNW, although ground observers confirmed that no eruption took place; emissions were only steam and gas.
It has one of the longest records of historic eruptions in the SE Pacific region. Sinabung is among more than 120 active volcanoes in Indonesia, which is prone to seismic upheaval due to Terms of use: Whilst we strive for 100% event reporting accuracy, delays and omissions may occur. Thursday, Mar 26, 2020 Manam volcano (Papua New Guinea): recorded eruption, first since Nov 2019 On 20 March Volcanic Ash Advisory Center (VAAC) Darwin recorded an explosion at the volcano that generated an ash plume, which reached approx.
This information is supplemented with aviation alerts from the Darwin Volcanic Ash Advisory Center (VAAC). The current eruption, ongoing since June 2014, produced multiple large explosive eruptions during January-September 2019, including two 15-km-high ash plumes in January, repeated SOThis report covers continued activity during October 2019 through March 2020.
Visitors to the summit on 18 October 2019 recorded steam and fumarolic activity at both of the summit craters (figure 72) and recent avalanche debris on the steep slopes (figure 73).On 2 November, a single large explosion at 1330 local time produced a thick, dark ash plume that rose about 1,000 m above the summit and drifted NW. Sulfur dioxide emissions persisted throughout the period producing emissions greater than 2.0 Dobson Units that were recorded in satellite data 3-13 days each month.The Darwin VAAC reported an ash plume in visible satellite imagery moving NW at 3.1 km altitude on 2 October 2019. RVO reported an increase in seismicity on 6 November about 90 minutes before the start of a new eruption from the Main Crater which occurred between 1600 and 1630; it produced light to dark gray ash clouds that rose about 1,000 m above the summit and drifted NW.
Mount Sinabung spews volcanic materials into the air as it erupts, in Karo, North Sumatra, Indonesia, Monday. RVO reported incandescence at night during the first week of October. Figure 74. RVO reported an increase in seismicity on 6 November about 90 minutes before the start of a new eruption from the Main Crater which occurred between 1600 and 1630; it produced light to dark gray ash clouds that rose about 1,000 m above the summit and drifted NW. Attempts to get an official comment from the Rabaul Volcano Observatory (RVO) office both in Bogia and in East New Britain yesterday were to no avail. This information is supplemented with aviation alerts from the Darwin Volcanic Ash Advisory Center (VAAC).
The larger eruptions of Manam produce pyroclastic flows and sometimes lava flows. SO 2 emissions at Manam exceeded 2 Dobson Units multiple days each month between October 2019 and March 2020.
Eruption warning / minor activity: Aso (central Kyushu, Japan): Volcanic Ash Advisory (updated 29 Jun 2020) Barren Island (Indian Ocean): mild explosive activity from summit cone (updated 6 Nov 2019) Kadovar (Northeast of New Guinea): explosive eruption of the volcano continues (updated 3 Aug 2020) Karymsky (Kamchatka): continuing ash emissions (updated 1 Aug 2020) Kerinci (Sumatra): Volcanic …
Incandescence associated with an ash plume from Manam volcano (image: Sentinel 2) On 20 March Volcanic Ash Advisory Center (VAAC) Darwin recorded an explosion at the volcano that generated an ash plume, which reached approx. Volcano Profile | Weekly Report (5 August-11 August 2020)
Incandescent ejecta was visible at the start of the explosion and continued with intermittent strong pulses after dark, reaching peak intensity around 1900. On 30 November 2019 (top middle), in addition to a plume drifting N from Manam, a small SO 2 plume was detected at Bagana on Bougainville Island, 1150 km E. A shockwave from the explosion was felt at the Bogia Government station located 40 km SE on the mainland about 1 minute later.

There were no further reports of explosive activity until the Darwin VAAC reported an ash emission in visible satellite imagery on 20 March 2020 that rose to 3.1 km altitude and drifted E for a few hours before dissipating.Although explosive activity was minimal during the period, SOMinor explosive activity, continued thermal activity, and SOMIROVA (Middle InfraRed Observation of Volcanic Activity)
