Overview

Vilyuchinsky, or Vilyuchik, is a steep-sided Pleistocene-to-Holocene stratovolcano south of Avachinsky Bay. Deep erosional gullies dissect the flanks, with Lava domes and young basaltic cinder cones at its base. Most of the growth of the volcano took place during the late Pleistocene.

The last significant eruption took place from the summit crater about 10,000 years ago, producing a moderate airfall deposit and a lava flow. Landslides and rock avalanches have affected habited areas.

Regional Volcanic Activity
The Northwestern Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Vilyuchik is a Holocene volcano that forms a prominent landmark south of Avachinsky Bay. It is seen here from the south between Mutnovsky and Gorely volcanoes. Deep erosional valleys are visible on the flanks, and lava domes scoria cones were constructed at its base.
