| Abstract: | Tianchi volcano is an active volcano with potential danger of eruption in the future,the hazards of lahar is the most important dissaster of volcano eruption, According to the field characteristic of deposits and the distance from crater,lahar deposit can be divided into debris flow hyperconcent rated streamflow at the base of field study,we describe deposits of(1 000 a.) B.P eruption in detail,if Changbaishan volcano were eruption again,the principal dissaster would be due to the hazards of lahar. |

| Keywords: | Tianchi volcano lahar hazards distribution characteristic. |
