Magnitude-frequency analysis is used here as a statistical method to quantify the erosion produced by rapid shallow failures in a glaciated basin of coastal British Columbia. Coupling air photo and ground-derived data we prove that the deviation from power-law distribution observed for small magnitude is an artefact of detection deficiencies. However, the total distribution shows to be not sensitive to the occurrence of small mass failures and total erosion remains well represented in the API-derived data. Our dataset also denotes a real deviation from simple scaling at much higher magnitudes, the cause of which is currently under investigation.

Abstract
Magnitude-frequency analysis is used here as a statistical method to quantify the erosion produced by rapid shallow failures in a glaciated basin of coastal British Columbia. Coupling air photo and ground-derived data we prove that the deviation from power-law distribution observed for small magnitude is an artefact of detection deficiencies. However, the total distribution shows to be not sensitive to the occurrence of small mass failures and total erosion remains well represented in the API-derived data. Our dataset also denotes a real deviation from simple scaling at much higher magnitudes, the cause of which is currently under investigation.
