2023 Jul 7: An explosive eruption at Bagana on 7 July send a large ash, gas, and steam plume to high altitudes and caused significant ashfall in local communities. A report issued by theAutonomous Bougainville Government (Torokina District, Education Section) on 10 July noted that significant ash began falling during 2000-2100 on 7 July and covered most areas in the Vuakovi, Gotana (9 km SW), Koromaketo, Laruma and Atsilima villages. By about 2200 on 7 July the eruption plume had reached upper tropospheric altitudes based onsatellite images. Sulfur dioxide detections in satellite images from 8 July indicated that theplume, likely a mixture of gases, ice, and ash, had risen to 16-18 km (52,500-59,100 ft) a.s.l.,reaching the tropopause. Ashfall reportedly continued until 9 July. The ashfall covered vegetation, destroying bushes and gardens, and contaminated rivers and streams used for washing and drinking water; residents drank from coconuts and used fresh ground water accessible through bamboo pipes. (reference #13574) An explosive eruption at Bagana on 15 July was similar to one that occurred on 7 July. According to the Darwin VAAC, an eruption at around 0830 on 15 July produced an ash plume that rose to 16.5 km (54,000 ft) a.s.l. by 1000 and drifted N based on satellite images. Ground-based reports indicated that pyroclastic flows had occurred in the vicinity of the volcano; small deposits confined to one drainage were inspected by RVO during an overflight on 17 July, and were confirmed to be from the 7 July event. The Autonomous Bougainville Government (ABG) issued a statement on 17 July noting significant impacts of ashfall in local communities. According to the National Disaster Centre, ashfall from the first event lasted until 10 July; an eruption was also reported by RVO on 14 July. Ashfall (presumably from events on 7 and 15 July) impacted about 8,111 people in Torokina, South Bougainville, including Tsito/Vuakovi, Gotana (9 km SW), Koromaketo, Kenaia, Longkogari, Kenbaki, Piva (13 km SW), and Atsinima (27km WNW) and in the Tsitovi district according to ABG. Significant ashfall was also reported in Ruruvu (22 km N) in the Wakunai District of Central Bougainville. An evacuation was called for the villages in Wakunai, where heavy ashfall had contaminated water sources; the communities of Ruruvu, Togarau, Kakarapaia, Karauturi, Atao, and Kuritaturi were asked to evacuate to a disaster center at the Wakunai District Station within 24 hours. Communities in Torokina, nearest to Bagana, were to immediately evacuate to the Piva District station. (reference 13575) According to new articles, more than 7,000 people needed temporary accommodations due to the eruption at Bagana, with about 1,000 of those in evacuation shelters. Ashfall was deposited over a broad area, contaminating water supplies, affecting crops, and collapsing some roofs and houses in rural areas. Schools were temporarily shut down. (reference #13576) The Internally Displaced Persons also provided account of destruction to the food gardens, cash crops, water source, as a result of ash falls. The current four affected wards are the main suppliers of fresh produce to Wakunai, Arawa and Buka, especially providing potato, cabbage, onion and sago tips. The number of livestock losses is unknown, but some have reported village chickens are dying and may be from drinking contaminated stagnant waters in ponds in the village. The main crops that 5 are affected across all four wards include, sweet potato (kaukau), taro, banana, sugar cane, Singaporean taro (taro kong-kong), sago palm tree and cooking banana. Reports of cocoa, vanilla and other economic crops suffered extensive damage as well due to the heavy ash falls. (reference #13578) Cited references #2432 Venzke, E., R.W. Wunderman, L.

2023 Jan 31: Reference #13678: The East Epi group, consisting of multiple submarine cones within a postulated caldera, lies off the eastern coast of Epi Island in Vanuatu (figure 6). Three cones (Epi A, B, and C) are located 4-10 km NNE from the Epi Island, with additional smaller cones south of Epi B (figure 7). Ephemeral islands were formed during eruptions in 1920 and 1953. Explosive activity was reported in 1958 and 1960, discolored water was often seen during 1971-1974 and 1988, a new vent was detected in 1979, and explosive activity occurred in February 1999, March 2002, and February 2004. A March 2004 bathymetric survey revealed that Epi B was about 300 m tall with a diameter of about 1.8 km at the base; the summit crater was about 150 m in diameter, the crater floor was at a depth of 90 m, and the highest point was on the NW rim of the summit crater, at a depth of 34 m. This report covers a new eruption during January through February 2023 that was characterized by phreatic explosions, a growing cone, and ash emissions. Information primarily comes from the Vanuatu Meteorology and Geo-Hazards Department (VMGD). According to the Wellington VAAC, a low-level ash and sulfur dioxide plume was identified in satellite data at 0730 on 31 January 2023. VMGD reported that residents saw gas-and-steam emissions at the ocean’s surface around 0748 (figure 8) and phreatic explosions that ejected gas and tephra 100 m above the water (figure 9). Observers also reported that they saw a growing cone from ongoing ash emissions. The Wellington VAAC noted that the eruption was short-lived and had stopped by 1548 when the ash had dissipated. During an overflight on the afternoon of 31 January, gas-and-steam was observed rising from the ocean surface above Epi B, discolored water was visible around the eruption site, and pumice rafts were floating on the surface (figure 10). Several strands of pumice that drifted to the SW, NW, and N of Epi B were visible in Sentinel-2 satellite imagery on 2 and 14 February (figure 11). Gas-and-steam emissions were also visible at the surface for a few hours during 1 February. During 0700-1030 on 7 February residents observed minor, low-level gas-and-steam emissions above Epi B. The intensity of the gas-and-steam plumes varied, with stronger activity reported by local residents around 0600 on 8 February. On 23 February VMGD reported sustained seismicity and minor gas-and-steam plumes that only lasted a few hours. Two main explosions were recorded by different monitoring networks, including seismic stations and the infrasound array located in Papua New Guinea (Figure 3). Although this had no apparent consequence on the nearby communities, a small tsunami was however reported by locals and recorded on the coastal tide gauges of Port-Vila to the South and Luganville to the North showing a maximum amplitude of ~5 cm.
