1 Year Magnitude Number Distribution

(top)

Legend

• Mean (thick black line): mean expected number across all 25000 catalogs
• 2.5%,97.5% (thin black lines): expected number percentiles across all 25000 catalogs
• Median (thin blue line): median expected number across all 25000 catalogs
• Mode (thin cyan line): modal expected number across all 25000 catalogs
• 1 yr Probability (thin red line): 1 year probability calculated as the fraction of catalogs with at least 1 occurrence
• 1 yr Supraseismogenic Probability (thin dashed red line): same as above, but only for supraseismogenic ruptures on explicitly modeled UCERF3 faults

Hazard Change Over Time

(top)

These plots show how the probability of ruptures of various magnitudes within 100km of any scenario rupture changes over time

M≥5.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 1 year are included

M≥6.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 1 year are included

M≥7.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 1 year are included

M≥8.0 Hazard Change Over Time

(top)

* forecast duration is longer than simulation length, only ETAS ruptures from the first 1 year 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.
