Abstract
Micro-scale debris flow event systems indicated a range of recurrence intervals for large debris flows from 106â3645Â years. The spatial variation of these rates across the fans was generally consistent with previously mapped hazard zones. At the fan meso-scale, the range of recurrence intervals for large debris flows was 273â1566Â years and at the regional scale, the estimated recurrence interval of large debris flows was 874Â years (with undetermined error bands) during the past 7290Â years. Dated lake sediments from the adjacent Lake Whatcom gave recurrence intervals for large sediment producing events ranging from 481â557Â years over the past 3900Â years and clearly discernible sedimentation events in the lacustrine sediments had a recurrence interval of 67â78Â years over that same period.
