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.

The volcano's activity has calmed down after the sudden strong explosions 2 days ago.
According to KVERT, a lava flow descended on the northwestern flank (although this might be the hot deposit from the pyroclastic flow during the explosive activity). Webcam imagery shows a strong decrease in heat at the summit although degassing remains elevated.
KVERT lowered the Aviation Color Code back to orange only 6 hours after the second explosion on 9 March.
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]
Introduction to Plate Tectonics: The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
