摘　　要：Volcanic hazard zoning is an effective way to reduce and mitigate volcanic risks.Due to its frequent magmatic unrest and potential for catastrophic eruption,the Changbaishan-Tianchi Volcano is currently the focus of attention for volcanic disaster prevention in China.This study uses past eruption data obtained from geological surveys and geochronological studies,to construct simulations of tephra fall,pyroclastic flows,lava flows,and lahars.Several widely accepted numerical models were adopted to simulate each hazard at different eruption scales.Hazard zoning was then conducted,producing a comprehensive hazards map of the Changbaishan-Tianchi Volcano.The map identifies areas of high,medium,and low hazard,mostly at 0-15,15-60,60-100 km from the edifice.This work serves as the scientific basis for the authorities and general public in the areas around the Changbaishan-Tianchi Volcano in planning for future response,as well as provides a reference for hazard zoning in other areas potentially affected by volcanic hazards.
