SERNAGEOMIN reported that after increased seismicity at Llaima on 14 July, an ash plume rose to an altitude of 5.6 km (18,400 ft) a.s.l. Less than two hours later, very intense orange and red incandescence was seen through breaks in the cloud cover near the summit and at the base of the W flank. At 1915 a vigorous Strombolian eruption ejected incandescent pyroclastic material from the N vent in the main crater to heights of 500 m above the summit. ...mehr [alles lesen]

Okmok Volcano continues to erupt. Seismicity, though below this weekend's intensity, has remained steady over the last 24 hours. Satellite data continue to show a long (~250 km) plume moving east; the height of the plume is approximately 30,000 ft above sea level. [alles lesen]

The strong eruption at Okmok continues based on ongoing seismic activity and satellite observations. Ash emissions continue reaching altitudes of 30,000 - 35,000 ft asl, and are posing a large hazard to all aircraft in the area. [alles lesen]

A large explosive eruption at Okmok volcano began at approximately 11:43 AM local time on July 12 and continues. An ash cloud with a top of at least 30,000-35,000 ft. height above sea level is present. ...mehr [alles lesen]

Llaima volcano is active again. On 1 July, a lava flow was seen on the W flank prompting authorities to evacuate about 20-30 people and warn others of possible further evacuations. The lava flow descended the W flank to 800-1000 m from the crater. [alles lesen]

Am 21 Juni 2008 wurde im wunderschönen Dorf Nikia auf der Insel Nisyros das neue Vulkanmuseum eingeweiht. Zahlreiche Besucher, sowie wichtige Politiker und religiöse Oberhäupter der Dodekanes nahmen an der festlichen Veranstaltung teil. Geplant und realisiert haben das Museum ein Team um die beiden griechischen Geologen Dr. Giorgis Voujoukalakis und Dr. Michalis Fytikas. Beide kämpfen seit vielen Jahren für den Schutz und das Marketing der aktiv geltenden Vulkane in Griechenland. Im Museum gibt es sehr ausführliche Erklärungen zum Vulkanismus allgemein und zur Vulkaninsel Nisyros. Zahlreiche Gesteinsproben, Mineralien und Fossilien machen das Geheimnis des Vulkanismus zugänglich. ...mehr [alles lesen]

Over the past weeks, activity at from Santa María's Santiaguito lava dome complex was mild to low, producing produced ash plumes rising to 4.1-4.4 km (13,500-14,400 ft) a.s.l. [alles lesen]

Mild strombolian activity continues at Fuego volcano. Incandescent material is thrown out up to 50 m above the vent on the summit crater and a small lava flow was observed on 13 June, travelling 100 m towards the Santa Teresa ravine on the W flank. Ash plumes reach altitudes of 3.9-4.4 km (12,800-14,400 ft) a.s.l. ...mehr [alles lesen]

As the Geophysical Institute of Ecuador reports, the eruption at Cerro Azul has resumed. A new eruptive fissure, about 400-500 long, opened on the SE flank on 3 June at 20h45 local time. Initial 60 m high lava fountaining and new lava flows were produced. The lava flows are directed towards the south coast of the island. Satellite imagery shows a 50 km long ash and gas plumes drifting north. [alles lesen]
