seismicity
Ground tremor frequency
Seismicity refers to the frequency, distribution, and intensity of earthquakes in a given area over time.
Geologists assess a region's seismicity to evaluate earthquake risk: California's high seismicity makes building codes critical.
The term appears in scientific and policy contexts discussing natural hazards and fault activity.
