The 2012 east Indian Ocean earthquake that had a moment magnitude of 8.6 is the largest strike-slip event ever recorded. Here we show that the rate of occurrence of remote M[thinsp][ge][thinsp]5.5 earthquakes (>1,500[thinsp]kilometres from the epicentre) increased nearly fivefold for six days after the 2012 event, and extended in magnitude to M[thinsp][le][thinsp]7. These global aftershocks were located along the four lobes of Love-wave radiation; all struck where the dynamic shear strain is calculated to exceed 10-7 for at least 100 seconds during dynamic-wave passage. The other M[thinsp][ge][thinsp]8.5 mainshocks during the past decade are thrusts; after these events, the global rate of occurrence of remote M[thinsp][ge][thinsp]5.5 events increased by about one-third the rate following the 2012 shock and lasted for only two days, a weaker but possibly real increase. We suggest that the unprecedented delayed triggering power of the 2012 earthquake may have arisen because of its strike-slip source geometry or because the event struck at a time of an unusually low global earthquake rate, perhaps increasing the number of nucleation sites that were very close to failure.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The 11 April 2012 east Indian Ocean earthquake triggered large aftershocks worldwide","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-15 01:32:19.536826","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2012-10-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000309733300047","VABBcode":null,"OpenAcc":0,"DOI":"10.1038/nature11504"},"refs":null,"anarec":{"AnaID":219209,"PubliDate":2012,"Pagination":"250-253","XtraPublOfAnaID":null,"ISBN":null,"Volume":"490","Issue":"7419","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43431,"SerRR":"Nature: International Weekly Journal of Science.
