The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Bezymianny ("unnamed") was considered extinct until it erupted violently in 1955-56, after a slumber of probably 1000 years. It is one of the most active volcanoes in Kamchatka. The eruption followed a massive flank failure (similar to Mt. St. Helens eruption in 1980) which removed a 0.5 sq km sector of the volcano.

Ash plume from Bezyianny's second explosion on 9 March 2017 (image: KB-GS-RAS, annotatons: Culture Volcan)
The two ash plumes from the explosions, an a third more discrete one from a pyroclastic flow on the north-west slope (block avalanche or pyroclastic flow) (image: KB-GS-RAS, annotations: Culture Volcan)
A phase of strong explosions occurred at the volcano on 9 March. The activity came as a surprise in its intensity after the volcano had been relatively calm during the previous weeks.
Starting shortly before 14:00 local time, two distinct explosions took place at the volcano at an interval of 30 minutes. Both generated large ash plumes that rose to estimated 10 km altitude and drifted northwest.
After only two hours, the ash had reached more than 350 km distance and drifted over the Gulf of Chelikhov in the northeastern part of the Sea of Okhostsk.
The explosions were also accompanied by pyroclastic flows that descended on the NW side of the volcano. Whether these were generated by the partial collapse of the eruption column, or by collapse of parts of the summit lava dome, or a combination of both is unknown.
The last activity of the volcano was in late 2016 when a small lava dome appeared in the summit crater.
KVERT reported strong gas-and-steam emissions at Bezymianny during 16-23 December; a gas-and-steam plume drifted about 60 km SW on 18 December. A daily thermal anomaly was detected over the volcano. The Aviation Color Code remained at Orange. ... [more]
Batu Tara photos: A remote island in the Flores Sea of Indonesia formed by a single volcano that has been in strong strombolian eruption for years. We regularly lead expeditions to there where we camp several days to observe it.
