The volcano is located in the central part of Ketoi Island

The cone of Pallas Peak is somewhat elongated from southwest to northeast. The relative height of the cone above the level of Lake Ketoy is 320 m, the total width of its crater along its long axis is 550 m, and at the bottom of it there is the Glazok crater lake with a diameter of 300 m.

Ash clouds, ash falls, pyroclastic flows, hot avalanches and lahars are a potential hazard associated with explosive eruptions of this volcano. The volcano poses a potential hazard to international and local airlines passing in the Kuriles region, since the height of its ash emissions can reach 10-15 km above sea level, ash plumes and clouds can drift hundreds of kilometers from the volcano in different directions. In addition, the outflow of lava flows onto the slopes of the volcano and the surrounding area is possibly.
