KuvaEbeko (Russia)

According to volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions during 16-17 July produced ash plumes that rose as high as 3 km (10,000 ft) a.s.l. and drifted E. Thermal anomalies were identified in satellite images during 16 and 20-22 July. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

KuvaSuwanosejima (Japan)

JMA reported ongoing explosions at Suwanosejima's Ontake Crater during 19-26 July and that crater incandescence was visible on some nights. There were 31 explosions recorded on 22 July after two days of no explosions. An explosion at 1500 on 23 July produced an ash plume that rose 1.6 km and ejected bombs 200 m. Eruption plumes during 23-26 July rose as high as 2.3 km; it was unknown if bombs were ejected from the crater due to weather conditions. The Alert Level remained at 3 and the public was warned to stay 2 km away from the crater.

KuvaMerapi (Indonesia)

BPPTKG reported that the lava dome just below Merapi?s SW rim and the lava dome in the summit crater both remained active during 16-22 July. The SW rim lava-dome volume was an estimated 1.88 million cubic meters and material continued to collapse down the flank. The volume of the summit lava dome was 2.808 million cubic meters. Lava avalanches traveled a maximum of 1.2 km SE (62 times), 1.8 km SW (101 times), 1.5 km W (two times), and 1.5 km NW (one time). Avalanches of material that descended the W flank originated from lava emplaced in 1992 and 1998, and material that descended the NW flank is from 1948 lava. According to the Darwin VAAC ash plumes rose to 3 km (10,000 ft) a.s.l. on 24 July and drifted WSW. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 5 km away from the summit.

KuvaLewotolok (Indonesia)

PVMBG reported that daily white-and-gray plumes from Lewotolok rose as high as 800 m and drifted in multiple directions during 20-25 July. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 3 km away from the summit crater.

KuvaTaal (Philippines)

PHIVOLCS lowered the Alert Level for Taal to 2 (on a scale of 0-5) on 23 July, noting that no eruptions had been recorded since the period of phreatomagmatic activity during 1-9 July. Additionally, an overall decrease was evident in multiple monitoring parameters. Sulfur dioxide emissions peaked at 22,628 tonnes/day on 4 July and declined to an average of 4,763 tonnes/day during 8-22 July. Steam plumes continued to be generated from the lake, rising 10-1,000 m, and lake upwelling was generally less vigorous. The DROMIC report stated that 794 people were in evacuation centers or private residences by 26 July. PHIVOLCS reminded the public that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ).

KuvaDukono (Indonesia)

Based on satellite and wind model data, the Darwin VAAC reported that during 21-26 July ash plumes from Dukono rose to 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted NE, E, and SE. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

KuvaKrysuvik

The fissure eruption in the W part of the Krýsuvík-Trölladyngja volcanic system, close to Fagradalsfjall on the Reykjanes Peninsula, continued during 21-27 July. Lava fountaining and overflows from the fifth vent were periodically visible, in between long pauses in the eruption, and lava from the crater flowed in tubes as well as on the surface. The Institute of Earth Sciences noted that during 2-19 July the lava effusion rate averaged 7.5 cubic meters per second, which was notably lower than averages in May and June. The area of the flow field had grown to almost 4 square kilometers, and the total volume erupted was 96 million cubic meters. Lava flowed into the Meradalir Valley and areas to the W, but did not advance in the Geldingadalur, Nátthaga, and Sydri Meradalir (SE of the fifth vent) valleys. The Aviation Color Code remained at Orange due to the lack of ash and tephra emissions, though IMO warned of the potential for lapilli and scoria fallout within a 650 m radius of the active vent. Authorities warned of increased gas emissions hazards.

KuvaSemisopochnoi (United States)

AVO lowered the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory for Semisopochnoi on 22 July, noting that explosive activity had not been detected since 12 July. Seismicity continued to be elevated during 23-27 July. Robust steam emissions were visible in webcam views during 22-24 July and sulfur dioxide plumes were identified in satellite images on 23 July. Weather clouds obscured views during 24-27 July.

KuvaSinabung (Indonesia)

PVMBG reported that white-and-gray plumes rose 100-300 m above Sinabung during 20-21 July and drifted N, NE, E, and SE. During 21-27 July white plumes rose as high as 400 m and drifted NE, E, and SE. At 1320 on 28 July an eruption produced an ash plume that rose 4.5 km above the summit and drifted E and S; the event lasted for about 12 and a half minutes. The Aviation Color Code was raised to Red. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

KuvaWhakaari/White Island (New Zealand)

GeoNet reported that crater incandescence at Whakaari/White Island, first seen on 30 June, continued to be visible in nighttime webcam images. The incandescence was attributed to high-temperature gasses. Additionally, the gas ratio of carbon dioxide to sulfur dioxide declined, indicating ongoing degassing from a shallow magma source. The Volcanic Alert Level was raised to 2 and the Aviation Color Code was raised to Yellow on 26 July.

KuvaGreat Sitkin (United States)

AVO reported that a satellite image of Great Sitkin acquired at 0932 on 22 July showed a small area of uplift, about 50 m in diameter, and elevated surface temperatures associated with the feature. These observations suggested magma rising near the surface, prompting AVO to raise the Aviation Color Code and the Volcano Alert Level to Orange and Watch, respectively. Small earthquakes were recorded during 23-25 July. A 26 July satellite image confirmed that the feature was a lava dome, and that it had grown to 130 m in diameter. Seismic data suggested that the dome probably emerged sometime during 14-22 July.

KuvaSirung (Indonesia)

PVMBG reported that a phreatic eruption at Sirung was recorded at 1644 on 21 July. A white-and-gray ash plume rose 2 km above the summit and drifted N. The report noted that the event was preceded by an increase in tremor amplitude that lasted about 10 hours; no volcanic earthquakes indicating magma movement were recorded and tremor amplitude did not notably increase. The Alert Level was raised to 2 (on a scale of 1-4), with visitors and tourists prohibited within a 1.5 km radius of Sirung.

KuvaTurrialba (Costa Rica)

OVSICORI-UNA reported that a one-minute-long eruption at Turrialba was recorded at 1130 on 23 July, though weather clouds prevented visual confirmation of an eruption plume. Ash fell in areas 3.5 km W.

KuvaAira (Japan)

JMA reported that incandescence from Minamidake Crater (at Aira Caldera?s Sakurajima volcano) was visible at night during 19-26 July. A very small eruptive event was recorded on 19 July. The sulfur dioxide emission rate was relatively elevated at 1,000 tons per day on 21 July. The Alert Level remained at 3 (on a 5-level scale), and residents were warned to stay 2 km away from the crater.

KuvaNyiragongo (DR Congo)

According to a news article a collapse in Nyiragongo?s main crater on 24 July caused white-colored ash to fall in Goma. The ashfall caused no notable damage, though there were health concerns related to water quality. The director of Volcanological Observatory of Goma (OVG) noted that the collapse was not due to eruptive activity.

KuvaSabancaya (Peru)

Instituto Geofísico del Perú (IGP) reported a daily average of 58 explosions at Sabancaya during 19-25 July. Gas-and-ash plumes rose as high as 2.3 km above the summit and drifted S, SE, E, and NE. Nine thermal anomalies originating from the lava dome in the summit crater were identified in satellite data. Minor inflation continued to be detected near Hualca Hualca (4 km N). The Alert Level remained at Orange (the second highest level on a four-color scale) and the public were warned to stay outside of a 12-km radius.

KuvaSoufriere St. Vincent (Saint Vincent and the Grenadines)

On 27 July the University of the West Indies Seismic Research Centre (UWI-SRC) reported that seismicity at Soufrière St. Vincent (often simply referred to as ?La Soufriere?) had remained low since the last episode of ash venting on 22 April. A few small daily earthquakes were recorded. Steam-and-gas plumes rose from some areas inside the crater and thermal anomalies persisted. The Alert Level remained at Orange.
