From early 2016 to late 2024, a swarm of earthquakes occurred near Cahuilla in Riverside County, California. More than 22,000 individual seismic events were recorded—ranging in magnitude from 0.7 to 4.4 -- the strongest one occurred in August 2024, south of Lake Riverside, just off Cahuilla Road ( SR … Prikaži več In seismology, an earthquake swarm is a sequence of seismic events occurring in a local area within a relatively short period. The time span used to define a swarm varies, but may be days, months, or years. Such an energy … Prikaži več The following examples were chosen for peculiarities of certain swarms (for instance: large number of events, complex interaction with larger shocks, long period of time, ultra-shallow focal depth), or because of their geographical region, some swarms … Prikaži več In the Ore Mountains (Erzgebirge), which form the border between the Czech Republic and Germany, western Bohemia and the Vogtland region, have been known since the 16th … Prikaži več • 1951 East Rift Valley earthquakes • 2009–23 Oklahoma earthquake swarms • Blanco Fracture Zone Prikaži več SpletSwarms are of particular interest because they likely result from physical changes in the crust, such as slow slip or fluid flow. ...

Splet24. sep. 2024 · Earthquakes can be abrupt bursts of home-crumbling, ground-buckling energy when slices of the planet’s crust long held in place by friction suddenly slip and lurch. New modeling shows for the first time that as pulses of high-pressure fluids travel upward along a fault, they can create earthquake swarms. (Image credit: iStock)
