WebFeb 23, 2024 · Seismicity is thus prone to occur without strong clustering in the form of mainshock-aftershock sequences, leading to a high fraction of nonclustered events. In the most extreme case, the fault is fully creeping except for a handful of tiny locked asperities, resulting in characteristic repeating earthquakes along the creeping segment ( 4, 33 ). WebJan 17, 1994 · The last modification concerns the time changeability of the seismicity in the future zone. When the hazard is due to expected seismic activity of many future zones and it is evaluated on a larger area, it can be safely assumed that the seismicity within the future zones does not change in time, though it can follow any of the alternative models (e.g., … brite computer education

"WebSeismicity as a function of lithospheric volume shows an even more dramatic decrease with age. The high seismicity rate in young oceanic lithosphere may indicate that thermoelastic stress, caused by the contraction of the oceanic lithosphere as it cools, is an important component in producing intraplate earthquakes in young oceanic lithosphere.

WebInduced seismicity associated with Enhanced Geothermal Systems WebThe term intraplate earthquake refers to a variety of earthquake that occurs within the interior of a tectonic plate; this stands in contrast to an interplate earthquake, which occurs at the boundary of a tectonic plate. Intraplate earthquakes are often called "intraslab earthquakes", especially when occurring in microplates.
