This plot gives the rate that each unique connection (between separate fault sections) is utilized.

Connection Rate Distribution

Fault Participation Rates

(top)

The rate at which each fault section participates in events in the listed magnitude range. Maps in the left column give rates above various magnitude thresholds, and in the right column rates between the given threshold and the next threshold level.

Rates are plotted on a log scale. Gray values mean that the rate is zero, and blue means that it is at or below the minimum plotted rate.

Regional Nucleation Rates

(top)

The gridded seismicity model attached to this solution is of type NSHM23_AbstractGridSourceProvider$Precomputed and has a spatial resolution of 0.1 degrees.

The following maps show the faulting type at each grid cell from the gridded seismicity model:

The following maps show the total nucleation rate in each grid cell, summed across both gridded seismicity and fault-based sources, as well as their individual contributions. Rates from faults are mapped to grid cells according to the model supplied association fractions.

Subsection b-values

(top)

These plots estimate a Gutenberg-Richter b-value for each subsection and parent section nucleation MFD. This is a rough approximation, and is intended primarily for model comparisons.

Note that b-values here are calculated from the branch-averaged nucleation MFD on each section, and do not represent the average of branch-specific b-values. The latter are plotted separately at the end of this section.

Connected Clusters

(top)

Connected clusters of fault sections, where all sections plotted in a given color connect with all other sections of the same color through ruptures. There may not be any single rupture that connects all such sections, but rather, chains of ruptures connect the sections. Only the first 10 clusters are plotted with bold colors; smaller clusters are plotted in random saturated colors (note that neighboring clusters can be similar colors by chance), and fully isolated faults are plotted in black.

Connection Passthrough Rates

(top)

Passthrough rates refer to the ratio of the jumping rate to the rates on either side of the jump. The denominator of that ratio can be either the minimum, maximum, or average of the subsection rates on either side of the jump. Each choice of denomiator is plotted separately.
