Tolbachik

Tolbachik (Russian: Толбачик) is a volcanic complex on the Kamchatka Peninsula in the far east of Russia.

It consists of two volcanoes, Plosky (flat) Tolbachik (3,085 m) and Ostry (sharp) Tolbachik (3,672 m), which as the names suggest are respectively a flat-topped shield volcano and a peaked stratovolcano.

It was preceded by an earthquake swarm, which led to a successful prediction of the eruption by scientists from the Russian Institute of Volcanology.

Basaltic lava flows move relatively fast, and quickly flooded buildings 4 km away.

[5][6][7] Lava flowed up to 20 kilometers (12 miles) from the line of fissures on the volcano's southern flank.
