seismicity

[ sahyz-mis-i-tee, sahys- ]

noun

, plural seis·mic·i·ties.

1. the frequency, intensity, and distribution of earthquakes in a given area.

seismicity

/ saɪzˈmɪsɪtɪ /

noun

1. seismic activity; the phenomenon of earthquake activity or the occurrence of artificially produced earth tremors

seismicity

/ sīz-mĭs′ĭ-tē /

1. The frequency or magnitude of earthquake activity in a given area. Global seismicity maps show that the regions where seismicity is the highest correspond with the edges of the tectonic plates.

Word History and Origins

Origin of seismicity¹

First recorded in 1900–05; seismic + -ity

Example Sentences

“If it had a return to a lot of seismicity, like we saw in 2004, with gas release and ground deformation, that would be the kind of scenario that might lead to evacuation.”

From Seattle Times

Wastewater injection has induced small to moderate-sized earthquakes around the world, however, making it important to study how CO2 injection produces seismicity and whether it might also induce larger earthquakes.

From Science Daily

"CO2 injection at Decatur is a good example. The first period of injection, the one we analyzed in the paper, led to hundreds of microearthquakes. The second period of injection, which took place at a shallower depth and not as close to the faulted basement, resulted in virtually no seismicity," Juanes said.

From Science Daily

Injection rates in CO2 projects have been "much, much lower" than wastewater injection rates in the 2000s and 2010s, said Juanes, which might explain why moderate-sized induced seismicity hasn't been seen at carbon sequestration projects.

From Science Daily

Human-made earthquakes, so called induced seismicity, have become an increasing concern.
