Current signal from OKRE seismic station on the northern flank of Okmok volcano 45 km (28 miles) to the S
Another major explosion has just occurred at the volcano producing an ash plume that reached flight level 330 (33,000 ft / 11 km altitude).
The Alaska Volcano Observatory reported a strong volcanic seismic signal from volcano starting at 21:18 AKST today (6:18 UTC Jan 4) and lasting ~5 minutes. In addition, a series of lightning strikes (typical for large ash plumes) were identified by the World Wide Lightning Location Network.
AVO raised the Aviation Color Code for Bogoslof to RED and Volcano Alert Level to Warning. However, the eruption was only short-lived (few minutes) and there were been no immediate "follow-up" eruptions detected. The volcano's warning level was soon after decreased again.
Another (the 6th) large explosion seems to be occurring this morning at the volcano. The Alaska Volcano Observatory reported detecting a strong seismic signal (captured on neighboring islands) and a swarm of lightnings typical for large eruption ash plumes near the volcano and extending north (as the ash plume drifts in this direction). ...

Another relatively large ash-producing explosive eruption occurred this morning (23:45 Dec 29 AKST local time / 08:45 Dec 30 UTC) from the volcano. The eruption was inferred from seismic data on nearby islands and seen in recent satellite images. ... [more]
Tours to active volcanoes: Watching a volcanic eruption is one of the most impressive natural displays. We have a wide selection of tours to active volcanoes worldwide at different activity and difficulty levels.
Eyjafjallajökull volcano photos: The volcano in Iceland with the unpronounceable name... but famous in 2010 when its ash clouds drifted over Europe and forced a unprecedented large-scale airspace closure for several days, stranding millions of passengers.
Volcano Special Tours: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
Photos from Greece: We have traveled and studied extensively in Greece, in particular on its active volcanic areas such as Santorini, Nisyros, Milos, Methana.
