Consequences and Aftermath of Hazard damaged about 1,300 houses - Between August
1992 and July 1993, Pyroclastic flows created an enormous apron of
loose fragmental deposits on the volcano's steep east side. Unzen's upper slopes owing to the death of vegetation, these deposits are a ready source of loose debris for generating lahars during rainstorms. Each period of heavy rain required sudden evacuation of several thousand residents.
