Semeru volcano (East Java, Indonesia): massive block and ash flow creates billowing ash plume

The volcano had a significant eruptive phase this afternoon. Starting at around 17:24 local time, a pyroclastic flow was observed that traveled a distance of approx. 4500 m, according to Indonesia's Civil Defense Agency BNPB.
The hot avalanche was likely caused by collapses of parts of the lava dome and/or upper parts of the lava flow on the steep southern slope of the volcano. Associated ash plumes rose to an altitude of 5500 m above sea level.
The volcanologists at the observatory registered a corresponding seismic signal with up to 22 mm amplitude that lasted for the considerable long period of 4287 seconds (approx. 1 hour 20 mins).

Another impressive video can be found on Pasek Made's page on facebook, from where the attached image stems.

Pilot tours
Exploring the unknown: We sometimes invite you to "test" new itineraries or destinations with us. Such trips are a reduced cost and require a higher degree of flexibility, but often offer a great deal of adventure.
Hawai'i
Volcano Tours on Hawai'i: The Hawaiian Islands are not only home to the most active volcanoes in the world, Kilauea and Mauna Loa on the Big Island, but also boast a unique natural environment. Born by volcanic activity of a very active hot spot in the middle of the Pacific Plate, they are a showcase of natural history.
