Physical Mechanisms Responsible for Aftershocks and Earthquake Swarms
摘要
ThisEarthquake swarm chapter discusses the physical mechanisms underlying long-lasting seismic activity clustered in particular regions, in contrast to Chap. 6 , which focused on dynamic rupture propagation during a single earthquake. Typical examples of such seismic activity are aftershocksAftershock and earthquake swarmsEarthquake swarm. AftershocksAftershock generally occur in the vicinity of the main-shock fault, and the activity decays following the Omori-Utsu lawOmori-Utsu law over a long period of time.
