Opala volcano, mountain in Russia
Opala is a stratovolcano in Ust-Bolsheretsky District with a cone-shaped structure that rises steeply from the surrounding landscape, reaching over 2400 meters in height. Its slopes are composed of layered volcanic rock, and the broad crater at the summit measures approximately 2 kilometers across, filled with hardened lava.
The volcano experienced one of its most powerful eruptions around 610 AD with high explosive force, leaving clear geological marks in the region. Another major eruption approximately 1500 years ago created the Barany Amphitheater depression on its southeast face.
Visiting this remote volcano requires preparation for rugged terrain with rocky surfaces and steep slopes, as well as variable mountain weather conditions. Those approaching it should bring sturdy equipment, weatherproof clothing, and experience with high-altitude hiking.
The volcano is classified as an ultra-prominent peak, meaning its elevation of over 2000 meters makes it stand out sharply from the surrounding landscape. This marked dominance makes it visible from great distances and gives the region a distinctive geological characteristic.
