KuvaVeniaminof (United States)

AVO reported that seismic data indicated that the eruption of lava from the cone in Veniaminof?s ice-filled summit caldera possibly paused on 6 December. Satellite data acquired on 10 December suggested lava effusion had stopped, though weak explosive activity from the vent possibly still occurred. No eruptive activity was evident in satellite and webcam images on the morning of 13 December. However, beginning in the afternoon intermittent tremor appeared and gradually became continuous. A plume, possibly containing ash, and elevated surface temperatures were identified in satellite and webcam images. A strong thermal anomaly was visible in satellite and webcam data during 14-15 December, and together with an eruption plume, was consistent with lava fountaining at the summit vent. By 16 December a lava flow was erupting from the vent. The Aviation Color Code remained at Orange (the second highest level on a four-color scale) and the Volcano Alert Level remained at Watch (the second highest level on a four-level scale).

KuvaManam (Papua New Guinea)

The Darwin VAAC reported that on 6 December ash plumes from Manam were identified in satellite images rising to an altitude of 5.2 km (17,000 ft) a.s.l. and drifting SE. RVO noted that at 1215 on 8 December seismicity increased and indicated an eruption had begun, according to a news article. The eruption was characterized by forceful ash emissions, explosions that ejected lava fragments above the crater, and rumbling and roaring noises. Around 1300, based on pilot observations, information from RVO, and satellite images, large ash plumes rose as high as 15.2 km (50,000 ft) a.s.l and drifted E. Island reports noted that ejections of material ceased around 1900; audible noises ended around 1930. Satellite data indicated that ash from the high-altitude plume had begun to dissipate by 2020, and that on-going ash emissions rose to 8.2 km (27,000 ft) a.s.l. Island residents described heavy ashfall and that the sun was blocked by airborne ash, based on second-hand social media posts. News reports indicated that residents in Bokure and Kolang (NE and ENE flanks, respectively) had evacuated. Seismicity had declined by the end of the day. Dark ash plumes continued to be visible the next day, rising as high as 7.6 km (25,000 ft) a.s.l. and drifting E, though were less frequent.

KuvaEtna (Italy)

INGV reported that during 3-9 December activity at Etna was characterized by gas emissions at the summit craters, with periodic Strombolian activity from vents in Bocca Nuova, Northeast Crater (NEC), and New Southeast Crater (NSEC). Strombolian explosions at the cone in NSEC became more frequent on 4 December. In addition, lava effusion became continuous with small overlapping flows traveling about 500 m down the E flank of the cone. Incandescent blocks generated by the lava flows rolled to the base of the cone, and occasional small collapses produced minor ash plumes. Strombolian activity and occasional ash emissions were characteristic of vents in the W part of Bocca Nuova?s (BN-1) crater floor. Gas emissions at Voragine Crater continued from a vent on the E rim of the crater, and Strombolian explosions were evident at NEC.

KuvaIbu (Indonesia)

PVMBG reported that on 11 December an ash plume from Ibu rose to 1.8 km (6,000 ft) a.s.l., according to the Darwin VAAC. Weather clouds prevented views of the plume in satellite data. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater, and 3.5 km away on the N side.

KuvaKilauea (United States)

HVO reported that lava at Kilauea?s Fissure 8 cone was last visible on 4 September, signaling the end of the Lower East Rift Zone (LERZ) eruptive phase. Consequently, the end of the LERZ eruption also marks the end of the over-arching, on-going eruption at Kilauea that began at the East Rift Zone (ERZ) in 1983. That determination was made by HVO in part by using the Global Volcanism Program guideline that an eruption should be considered over on the date of the last eruptive activity, and when there has not been renewed activity in the following three months. HVO noted that geophysical data continued to show magma being supplied to Kilauea, including the refilling of the middle ERZ, and reminded the public that Kilauea remains an active volcano. As of 4 December the Volcano Alert Level remained at Advisory and the Aviation Color Code remained at Yellow.

KuvaNevados de Chillan (Chile)

ONEMI and SERNAGEOMIN reported that at 0313 on 7 December an explosion at Nevados de Chillán was recorded by the seismic network, and produced a high-temperature emission of gas and tephra recorded by a webcam. The Alert Level remained at Orange, the second highest level on a four-color scale, and residents were reminded not to approach the crater within 3 km. ONEMI maintained an Alert Level Yellow (the middle level on a three-color scale) for the communities of Pinto, Coihueco, and San Fabián.

KuvaAmbrym (Vanuatu)

The Vanuatu Meteorology and Geo-hazards Department (VMGD) reported that a fissure eruption in the ESE part of the Ambrym summit caldera near the Lewlembwi crater (4 km SE of Marum) began at 0600 on 15 December, heralded by elevated seismicity detected by the seismic network and ash emissions visible in the webcam. A notice issued later that day by VMGD stated that lava flows and lava fountains were visible, and explosions were occurring. John Tasso, a local guide, visited the caldera a few hours after the new activity started and observed lava fountains from a fissure eruption; his video was posted to his website. The lava fountains were about 40 m high; lava flows spread to the E part of the caldera. Although partially obscured by a steam plume directly above the eruption site, infrared imagery from the Sentinel-2 satellite on 15 December showed lava filling much of the 500 x 900 m Lewlembwi crater and a lava flow almost as large a few hundred meters SW of that crater. VMGD raised the Alert Level to 3 and stated that the eruption was characterized as ?small scale.? The eruption continued during 16-17 December, though reports on 17 December only described ongoing ash-and-gas emissions.

KuvaCleveland (United States)

A small explosion at Cleveland was recorded by the seismic network at 1155 on 8 December. A second small explosion with a higher peak amplitude was detected at 1153 on 12 December, prompting AVO to raise the Aviation Color Code to Orange and the Volcano Alert Level to Watch. No ash cloud was observed, though weather clouds obscured views of the volcano. Elevated surface temperatures were visible in satellite data on 15 December. A small explosion which occurred at 0737 on 16 December generated a minor ash cloud that drifted NE.

KuvaPlanchon

Observatorio Volcanológico de los Andes del Sur (OVDAS)-SERNAGEOMIN and ONEMI reported increased activity at Planchón-Peteroa beginning in the morning of 16 December. Low-intensity pulses of tremor were detected by the seismic network and associated with pulsating grayish gas emissions which rose no higher than 800 m above the vent rim. Webcams recorded crater incandescence during the night of 15-16 December. The Alert Level remained at Yellow (the middle level on a three-color scale) for the volcano, and ONEMI maintained Alert Level Yellow for the communities of Molina (66 WNW), Curicó (68 km NW), Romeral (75 km NW), and Teno (68 km NW).

KuvaSoputan (Indonesia)

PVMBG reported that seismic activity at Soputan rapidly and significantly increased at 1700 on 15 December. An eruption began at 0102 on 16 December though dark and foggy conditions prevented views of emissions. The event lasted for almost 10 minutes, and thunderous sounds were heard at the Soputan Volcano Observation Post located in Silian Raya (about 10 km SW). The conditions improved about two hours later, and a dense ash plume was visible rising 3 km above the summit and drifting SE. Incandescence from the summit was also visible. An event that began at 0540 produced dense gray-to-black ash plumes that rose as high as 7 km above the summit and drifted SE. The event lasted for 6 minutes and 10 seconds based on the seismic network. Ash plumes from events at 0743 and 0857 rose as high as 7.5 km and drifted SW. The Alert Level remained at 3 (on a scale of 1-4). Residents and tourists were advised not to approach the craters within a radius of 4 km, or 6.5 km on the WSW flank.

KuvaPacaya (Guatemala)

In a special notice posted on 13 December INSIVUMEH reported that rumbling at Pacaya was heard within a radius of 8 km, and weak Strombolian explosions at Mackenney Crater ejected material as high as 50 m above the crater rim. Active lava flows were 200-300 m in length and traveled down the NW flank, generating avalanches of blocks that were as large as 1 m in diameter. The report also noted that the cone in the crater continued to grow, filling the crater, and was 75 m above the crater rim. During 15-16 December lava continued to flow NW and Strombolian explosions ejected material 5-25 m high.

KuvaSangay (Ecuador)

IG reported that the eruption at Sangay that began on 8 August ended on 7 December after about four months of activity. The eruption was characterized by the extrusion of lava flows, and ash emissions that rose between 0.5-1.4 km (and occasionally higher than 2 km) and mainly drifted W and NW. Minor amounts of ash fell in Guayaquil on 18 September. Lava flows traveled 1-2 km down the ESE flank, and both block avalanches and possible small pyroclastic flows from the flow fronts traveled additionally as far as 7 km.
