Worldwide Volcano News and Updates

Fuego volcano continues to produce lava flows and strong strombolian explosions, and CENAPRED and CONRED warn about possibly pyroclastic flows that could be generated by collapsing lava flow fronts and incandescent material rolling down the steep upper slopes of the volcano as has occurred before during the ongoing strong eruptive phase. It is therefore recommended not to stay within canyons in the vicinity of the volcano. The CONRED system maintains constant monitoring.

Nevado del Ruiz continues to produce significant sulfur dioxide emissions as well as ash venting. Seismic signals on 15 and 18 June indicated continuing ash emissions. Based on analysis of satellite imagery and web camera views, the Washington VAAC reported that on 17 June a 5.5-km-wide gas plume, possibly containing ash, drifted more than 90 km NW. The VAAC noted on 18 June that INGEOMINAS reported a gas-and-ash plume drifting N and NW at an altitude of 6.1 km (20,000 ft) a.s.l. The plume was later detected in satellite imagery drifting more than 90 km NW.

Cleveland volcano in the Aleutian Islands (Alaska) had an explosive eruption at 14.05 local time on 19 June, the Alaska Volcano Observatory (AVO) reported, who raised the alert status to Orange (3 out of 4). Based on pilots'observations, an ash plume rose to about 35,000 ft (10,6 km). As the eruptions blog writes, a possible explanation could be that the eruption was caused by a collapse of the lava dome, but Cleveland's remote location makes it difficult to confirm this.

The new Smithsonian / USGS Weekly Volcanic Activity Report is summarized as follows: Read allOn 13 June ash plumes rose 2-2.5 km above the crater and drifted NE and N. Ashfall was reported in Cusúa (8 km NW) and Bilbao (8 km W). An explosion the next day caused windows to vibrate in areas 8 km SW and N. Steam plumes rose .5-2 km above the crater during 16-18 June. Windows in Manzano (8 km SW) vibrated during 18-19 June, and ashfall was reported in Palitagua, Runtún (6 km NNE), and Choglontús (SW).

JMA reported that during 11-15 June large explosive eruptions from Sakura-jima's Showa Crater occurred 5 times and ejected tephra as far as 800 m from the crater. A small eruption from Minami-dake Crater occurred on 13 June. Read all

Incandescence from the crater was occasionally visible at night. During 13-15 June gas-and-ash plumes that rose above the crater sometimes drifting NW and W. Ejected tephra fell onto the E, N, and W flanks, as far away as 500 m from the crater.

KVERT reported that moderate seismic activity from Karymsky continued to be detected during 8-15 June, and indicated that possible ash plumes rose to an altitude of 3 km (9,800 ft) a.s.l. during 8-13 June. Meteorological cloud cover prevented satellite image views. Based on analysis of seismic data, KVERT reported that on 18 June possible ash plumes rose to an altitude of 3 km (10,000 ft) a.s.l.
