Hazard Change Over Time

(top)

These plots show how the probability of ruptures of various magnitudes within the region used to fetch ComCat trigger ruptures changes over time

M≥5.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 10 years are included

M≥6.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 10 years are included

M≥7.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 10 years are included

M≥8.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 10 years are included

Individual Simulated Catalog Maps

(top)

These are map plots of individual catalogs from the simulations, selected as the closest catalog to each of the given percentiles in terms of total number of events.

ComCat Data Comparisons

(top)

These plots compare simulated sequences with data from ComCat. All plots only consider events with hypocenters inside the ComCat region defined in the JSON input file.

Last updated at 2024/10/17 23:16:37 UTC, 30.8 years after the simulation start time.

Total matching ComCat events found: 1362

ComCat Magnitude-Time Functions

(top)

These plots show the show the magnitude versus time probability function since simulation start. Observed event data lie on top, with those input to the simulation plotted as magenta circles and those that occurred after the simulation start time as cyan circles. Time is relative to the mainshock (M6.7, ci3144585, plotted as a brown circle). Probabilities are only shown above the minimum simulated magnitude, M=2.5.

ComCat Time-Dependent Mc

(top)

The following plots compare simulation results with ComCat data above a magnitude threshold. Plots labeled as M≥Mc(t) use the time-dependent magnitude of completeness (Mc) defined in Helmstetter et al. (2006), which is plotted below. In the case of multiple M≥5 ruptures, either as input to the simulation or in the comparison data, the maximum calculated time-dependent Mc is used. This time-dependent Mc function is plotted below.
