Worldwide Volcano News and Updates

JMA reported that nighttime incandescence at Minamidake Crater (at Aira Caldera's Sakurajima volcano) was visible during 28 June-4 July. Two eruptive events and one explosion produced plumes that rose as high as 1.6 km above the crater rim. An explosion, the first recorded since 28 January, was detected at 1221 on 27 June and ejected tephra 600-900 m above the crater rim. Read all

AVO reported that strong winds in a region NW of Aniakchak and E of Port Heiden resuspended ash and blew it NW on 30 June. A dense cloud of possible resuspended ash near ground levels was identified in Port Heiden webcam views. The altitude of the cloud was unknown, though the report noted that resuspended ash clouds typically do not rise above 5 km (16,400 ft) a.s.l. Read all

Based on satellite and wind model data, the Darwin VAAC reported that during 29 June-1 July ash plumes from Dukono rose to 2.1 km (7,000 ft) a.s.l. and drifted W. 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. Read all

INSIVUMEH reported that 4-10 explosions per hour were recorded at Fuego during 28 June-5 July, generating ash plumes that rose as high as 1.2 km above the crater rim. The ash plumes drifted 10-30 km W and SW, causing daily ashfall in areas downwind including Morelia (9 km SW), Panimaché I and II (8 km SW), Santa Sofía (12 km SW), El Porvenir (8 km ENE), Los Yucales (12 km SW), Sangre de Cristo (8 km WSW), and Finca Palo Verde. Daily shock waves rattled structures in communities around the volcano and occasional rumbling was heard. Read all

AVO reported that the eruption at Great Sitkin continued during 29 June-5 July. The lava-flow field grew slightly, expanding 15 m E. Elevated surface temperatures were occasionally identified in satellite images; weather clouds sometimes obscured satellite and webcam views. Read all

PHIVOLCS issued a special notice for Kanlaon at 1400 on 3 July, noting increased earthquake activity beneath the summit. A total of 41 volcanic earthquakes were recorded by the seismic network beginning at 0500 on 30 June, including seven shallow tornillo signals indicating gas movement through fractures in the upper flanks. Ground deformation data from continuous GPS indicated minor, short-term inflation of the lower and mid-flanks of the volcano since January 2022, consistent with continuous electronic tilt data that had recorded inflation on the SE flanks since mid-March 2022.

AVO reported that on 30 June strong winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes blew unconsolidated ash NW at an altitude up to 1.8 km (6,000 ft) a.s.l. The ash was originally deposited during the Novarupta eruption in 1912. The Volcano Alert Level remained at Normal and the Aviation Color Code remained at Green. Read all
