Moderate potential hazards are caused by ash plumes, ash falls, pyroclastic flows, hot avalanches and lahars.

The volcano constitutes a potential hazard to international and local airlines at Kamchatka because its eruptive clouds can rise to a height of 3-20 km ASL and extend for hundreds of kilometers from the volcano.

Ash falls possible at:
Klyuchi (50 km to the south-west from the volcano)
Ust’-Kamchatsk (90 km to the east-southeast from the volcano)
Ust’-Khairyuzovo (280 km to the west-northwest from the volcano)

Sheveluch is one of the biggest volcanic structures in Kamchatka. The volcano includes three main units: Stary Sheveluch, the old caldera and active apparatus Molodoy Sheveluch.

1854 - powerful catastrophic eruption: ash falls, debris avalanche, pyroclastic flows. VEI - 3-4.
1879-1950 - growth of the lava dome Suelich and others into the explosive crater 1854.
1879-1883 - separate ash explosions.
1898 - paroxysmal explosive eruption connected with growth of the lava dome.
1897-1929 - separate ash explosions.
