Perhaps the modern cone rises directly from the bottom of the Sea of ​​Okhotsk, then the height of the Raikoke volcano is about 2500 m. At the top of the cone there is a large crater with a diameter of about 700 m and a depth of 200 m. The southeastern part of the ridge is slightly higher than the northwest. The walls of the crater are extremely steep, and the characteristic structure of the stratovolcano is visible in the cliffs. The southern slope is covered with pyroclastics, the eastern - with lava flows.

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 and thousands of kilometers from the volcano in different directions.
