KuvaAira (Japan)

JMA reported that there were eight events and seven explosions at Minamidake crater (at Aira Caldera?s Sakurajima volcano) during 30 July-6 August, with ash plumes rising as high as 2.5 km above the crater rim and material ejected as far as 700 m. Crater incandescence was seldom visible at night. Sulfur dioxide emissions were very high at 3,200 tons per day on 2 August. The Alert Level remained at 3 (on a 5-level scale).

KuvaCleveland (United States)

AVO reported that unrest at Cleveland continued during 25-31 July, though nothing significant was detected in seismic or infrasound data. Meteorological cloud cover prevented views of the crater on most days, though steaming from the crater was visible in satellite and webcam views during 25-26 July. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

KuvaDukono (Indonesia)

Based on satellite data, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 1 and 3-7 August ash plumes from Dukono rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted N and NE.

KuvaKilauea (United States)

HVO reported that the eruption at Kilauea?s Lower East Rift Zone (LERZ) and within Halema`uma`u Crater continued during 1-2 August, with lava flowing through the channel and into the ocean producing laze at several points along a broad 2-km-wide flow front at Ahalanui. A few spillovers from the channel set vegetation on fire. By 3 August the lava-flow velocity in the channel was low and on 4 August the output at Fissure 8 had waned. Part of the flow field shifted W about 250 m; the westernmost edge was about 70 m NE of the boat ramp in Isaac Hale Park by 5 August. The lava channel was completely crusted over by 6 August, and a lava lake bubbled in the Fissure 8 cone. The laze plumes at the ocean entry were greatly diminished. During 7-8 August the lava lake in Fissure 8 was 5-10 m below the spillway into the channel. A decreasing number of small active ooze outs near the coast were visible. A collapse event at the summit was recorded at 1155 on 2 August. Seismicity increased afterwards as has been typical since early on in the LERZ eruption, but then decreased along with the rate of deformation. By 7 August deformation had almost stopped. The quiet conditions at the summit represented a significant change from the pattern of seismicity and deformation detected over the past several months.

KuvaSabancaya (Peru)

Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosions at Sabancaya averaged 19 per day during 30 July-5 August.

KuvaKrakatau (Indonesia)

PVMBG reported that on 2 August multiple events at Anak Krakatau generated ash plumes that rose as high as 300 m above the summit and drifted N. A dense, black ash plume from an event at 1757 rose 200 m and drifted N. During 5-7 August dense gray ash plumes rose 200-600 m above the summit, and summit incandescence was visible at night.

KuvaAmbae (Vanuatu)

According to news articles and the Vanuatu Red Cross, residents of Ambae began to evacuate the island during 1-8 August under the governments orders due to the effects of significant ashfall from the ongoing eruption at Lake Voui. The Red Cross noted that by 8 August over 3,000 people had been moved to Espiritu Santo (W) and Maewo (NE) islands. Video from 3 August showed lahars blocking roads in S Ambae.

KuvaRinjani (Indonesia)

PVMBG and BNPB reported that a M 6.4 earthquake was recorded at 0547 on 29 July, shaking the islands of Lombok, Bali, and Sumbawa, and causing significant damage to buildings (including collapses) and roads, ground cracks, multiple injuries, and the death of 17 people in Lombok. The hypocenter was 24 km deep, and 47 km NE of Mataram City. Aftershocks were numerous and as large as M 5.7. The earthquakes caused remobilization of ash deposits on Rinjani as well as landslides. There were 1,226 visitors to the Mount Rinjani National Park Area at the time, and, according to news articles, about 690 climbers were on the volcano and had to be rescued. One person in the national park died from rockfalls. The Alert Level remained at 2 (on a scale of 1-4); the public was warned not to approach the crater within a 1.5-km radius.

KuvaEtna (Italy)

Based on two field inspections and webcam data, INGV reported that during 30 July-5 August activity at Etna was characterized by gas emissions at the summit craters and Strombolian activity. Three vents at the bottom of the Bocca Nuova crater were active, with gas emissions rising from two vents and sporadic Strombolian activity occurring at a third. Three vents were also active at the bottom of Northeast Crater (NEC); one produced ash emissions, one steam emissions, and Strombolian explosions at the third ejected incandescent material as high as the crater rim. After several months of quiet conditions, explosive activity resumed at the E crater on the E flank of the New Southeast Crater (NSEC). The activity began at 0608 on 1 August with a brownish-gray ash emission that rose several hundred meters above the summit. The event was followed by more ash emissions and then Strombolian activity in the evening.
