Volcanos

Roundup of Global Volcanic Activity

Fuego (Guatemala): During the past days, explosive activity has been relatively intense at the volcano. Strong strombolian-type explosions have been occurring at rates of 6-8 per hour, sometimes ejecting incandescent bombs to more than 1000 m above the crater and producing glowing avalanches. Some of these reached the vegetation and caused small fires. Ash plumes rose to 1-1.5 km above the crater and drifted 10-15 km to the west and southwest.

Hunga Tonga-Hunga Ha'apai (Tonga, Tonga Islands): The submarine eruption has apparently breached the surface. A steam and possibly ash plume was reported to have reached up to 30,000 ft (10 km) above sea level today and yesterday, New Zealand's VAAC Wellington reported, based on pilots' observations. According to local news, the domestic Real Tonga airline cancelled some flights in the area. Unconfirmed reports mention ash fall on Ha'apai Island. An Air New Zealand flight bound to Tonga was diverted to Samoa.

Kliuchevskoi (Kamchatka): Eruptive activity, strombolian explosions from the summit vent, has picked up during the past 1-2 days. A lava flow is now active on the southeastern flank and ash plumes have been reaching 28,000 ft (8.5 km) altitude. KVERT raised the volcano's alert level to orange. Incandescent material from the explosive summit activity is ejected to several hundred meters above the crater. Relatively intense ash emissions have been causing ash fall in up to 30 km distance to the west of the volcano.
