a Values of stress drop estimated from S waves as a function of focal depth. The red circles show average values for each depth band for every 10 km. Vertical bars express standard errors for individual earthquakes, as obtained from results at individual seismic stations and components. b Values of stress drop estimated from S waves as a function of magnitude. The red circles indicate average values for individual magnitude ranges. Vertical bars show standard errors (same as (a)). c Stress drops as a function of time for all the analyzed earthquakes. d Temporal characteristics of stress drop in the area C. e Temporal features of stress drop in the area D
