Northeastern Siberia, north of the Stanovoy Range, is an extremely mountainous region. The long Kamchatka Peninsula, which juts southward into the Sea of Okhotsk, includes many volcanic peaks, some of which are still active. The highest is the 4,750-meter Klyuchevskaya Sopka, the highest point in the Russian Far East. The volcanic chain continues from the southern tip of Kamchatka southward through the Kuril Islands chain and into Japan. Kamchatka also is one of Russia's two centers of seismic activity (the other is the Caucasus). In 1995, a major earthquake largely destroyed the oil-processing town of Neftegorsk. Also located in this region is the very large Beyenchime-Salaatin crater.
