The mountain is a major andesite volcano, with the magma known for its high levels of Nickel and Chromium.

Victory is dominantly Andesitic in origin, but also has traces of Basalt and Dacite, the lavas erupted have an unusually high level of Chromium and Nickel.

The summit now contains a small crater lake where weak thermal activity continues.

The eruption produced deadly Pyroclastic flows that probably resulted in the deaths reported by local residents in the 1890s.

The constant glow from Victory's long-term eruption (which could have ended as late as 1940) provided a beacon for passing ships.
