Figure 2
Scaling of the corner frequency with the seismic moment. (a), The corner frequency and the seismic moment estimates for each LFE are shown (grey points). The weighted averages of the corner frequencies for the selected seismic moment bins (bin-size, 0.03) are shown (red points), along with the weighted standard deviations per bin (red bars). The best-fit curve (blue line) of the averaged estimates (red points) has a scaling parameter of −3.5. The histogram in the background (grey shading) shows the number of events in each bin. The green line represents the scaling of −3. (b), Probability density function of the scaling parameter estimated by a bootstrap method performed with 100,000 random extractions (see Methods); colours as for the top panel.
