KuvaSheveluch (Russia)

KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 2 and 4-6 December. A strong explosive event on 5 December generated ash plumes that rose as high as 10.5 km (34,500 ft) a.s.l. and drifted NE. Ash plumes at 5 km (16,400 ft) a.s.l. drifted E. The Aviation Color Code remained at Orange.

KuvaCleveland (United States)

AVO reported that during 6-12 December no thermal anomalies were visible in mostly clear satellite images, and no activity was detected by seismic or infrasound sensors. AVO noted that lava effusion may have paused or stopped; a satellite image acquired on 26 November showed that the lava dome had the appearance of rubble in the bottom of the shallow crater. On 12 December AVO lowered the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory, though an explosion the next day prompted a return to Orange and Watch, respectively. That explosion on 13 December was detected at 0420, and produced an eruption cloud identified in satellite data rising to an altitude of 6.1 km (20,000 ft) a.s.l. and drifting E.

KuvaDukono (Indonesia)

Based on analyses of satellite imagery, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 6-10 and 12 December ash plumes from Dukono rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted NE, E, and SE.

KuvaKilauea (United States)

During 6-12 December HVO reported that the lava lake continued to rise, fall, and spatter in Kilauea?s Overlook crater. Webcams recorded incandescence from long-active sources within Pu'u 'O'o Crater and from a small lava pond in a pit on the W side of the crater. Surface lava flows were active above and on the pali, and on the coastal plain.

KuvaSabancaya (Peru)

Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosive activity at Sabancaya decreased compared to the previous week; there was an average of 63 explosions recorded per day during 4-10 December. Seismicity was dominated by long-period events, with signals indicating emissions. Gas-and-ash plumes rose 3 km above the crater rim and drifted 50 km NE and SW. The MIROVA system detected four thermal anomalies. The sulfur dioxide flux was high, at 1,392 tons per day on 4 December. The report noted that the public should not to approach the crater within a 12-km radius.

KuvaAgung (Indonesia)

Based on BNPB and PVMBG reports, the eruption at Agung continued during 6-12 December, with high seismicity and nighttime crater incandescence often visible. On 8 December at 0759 an event generated a dense ash plume that rose 2.1 km above the crater rim and drifted W. Minor amounts of ash were deposited on the flanks, and lapilli was reported in Temakung. An ash plume rose 3 km at 1457. The number of evacuees on 10 December was 70,079 (spread out in 237 shelters). Ash plumes rose as high as 2 km. Lahars were observed in a drainage originating on the flanks of Agung. An explosion at 0549 on 11 December generated a dense ash plume that rose 2.5 km and drifted W and NW. Multiple ash-plume events were observed during 11-12 December, with plumes rising 1.5 km above the crater rim. The Alert Level remained at 4 (on a scale of 1-4), and the exclusion zones continued at a general 8-km radius and 10 km in the NNE, SE, S, and SW directions.

KuvaPacaya (Guatemala)

INSIVUMEH reported that during 9-12 December Strombolian explosions at Pacaya?s Mackenney cone ejected material as high as 25 m above the main cone. Lava flows traveled 100 m NW towards Cerro Chino cone, and 75 m SE.

KuvaVillarrica (Chile)

On 10 December POVI reported that the surface of the lava lake in Villarrica?s crater was stable at 70 m below the crater rim. Ejected lava from the lake was not evident in images captured during the previous five days, and incandescence and seismicity slowly decreased.

KuvaKarymsky (Russia)

KVERT reported that a thermal anomaly over Karymsky was identified in satellite data during 3 and 5-6 December. An ash cloud rose to an altitude of km (9,000 ft) a.s.l. and drifted 200 km E on 4 December. The Aviation Color Code was raised to Orange (the second highest level on a four-color scale).

KuvaKanlaon (Philippines)

PHIVOLCS reported that an approximately 10-minute-long, low-energy phreatic eruption at Kanlaon began at 0947 on 9 December. A plume of voluminous steam and dark ash rose 3-4 km above the summit vent. The event was heard as far away as La Castellana, Negros Occidental. Minor amounts of ash fell in Sitio Guintubdan, and barangays Ara-al, Sag-ang, and Ilihan. The eruption was preceded by the resumption of degassing at the summit crater at 0634, detectable as continuous low-energy tremor during periods when the summit was not visible; degassing was last observed September 2016. The Alert Level remained at 2 (on a scale of 0-5).

KuvaShishaldin (United States)

AVO increased the Aviation Color Code for Shishaldin to Orange and the Volcano Alert Level to Watch on 6 December following several weeks of increasing seismicity and pressure waves recorded by infrasound sensors. Continuous infrasound waves were detected for more than 10 hours on instruments located in Sand Point, ~230 km E. Steam emissions visible in satellite and webcam images during 5 and 8-12 December were rising hundreds of feet above the summit crater. The steam emissions were occasionally accompanied by infrasound signals indicating episodes of short-duration energetic gas emissions and/or small explosions.

KuvaAmbrym (Vanuatu)

On 7 December Vanuatu Geohazards Observatory (VGO) lowered the Alert Level for Ambrym to 2 (on a scale of 0-5), noting that activity had stabilized by the end of November and was characterized by gas-and-steam emissions. Seismicity had also declined. The report reminded the public to stay outside of the Permanent Danger Zone defined as a 1-km radius from Benbow Crater and a 2.7-km radius from Marum Crater.

KuvaFuego (Guatemala)

INSIVUMEH reported that the 12th effusive/explosive eruption at Fuego in 2017 began on 10 December and, based on seismicity, lasted for about 36 hours. Ash plumes from moderate-to-strong explosions rose as high as 1.2 km above the crater rim and drifted 20 km S and SW. Lava flowed as far as 1.5 km W down the Seca (Santa Teresa), SW down the Taniluyá, and SSW down the Ceniza ravines. Ash fell in the communities of La Rochela, San Andrés Osuna, Morelia (9 km SW), and Panimaché I and II (8 km SW). On 12 December there was an average of 10 explosions per hour, generating avalanches in the Ceniza and Taniluyá drainages and ashfall in nearby areas.

KuvaNevados de Chillan (Chile)

POVI reported that observations of Nevados de Chillán's Volcán Arrau dome complex during 7-11 December indicated phreatic explosions, ash emissions, and a new sulfur deposit on the flank. On 11 December Servicio Nacional de Geología and Minería (SERNAGEOMIN) reported that explosive activity generated an ash plume to 3 km above the complex.
