Fig. 6From: Spatial pattern in stress drops of moderate-sized earthquakes on the Pacific Plate off the south-east of Hokkaido, Japan: implications for the heterogeneity of frictional properties a Stress drops estimated from S waves as a function of focal depth. The red circles indicate average values for each depth bin for every 10Â km. Vertical bars indicate standard errors for individual earthquakes, as calculated from results at individual stations and components. b Stress drops estimated from S waves as a function of magnitude. The red circles indicate average values for individual magnitude bins. Vertical bars indicate standard errors (same as (a)). c Estimated values of stress drop as a function of timeBack to article page
