Iinyikima yenye yeentlekele zemvelo ezingunobangela wokufa kwabantu abaninzi. Ngelishwa, olu hlobo lwesenzeko zihlala zixelwa kwangaphambili ukwenzela ukuba indawo echaphazelekayo ikhutshwe ngokukhawuleza. Ukuzama ukwandisa, ngenye indlela, ukwandisa inani leesismographs ezinceda ekuqikeleleni ezi ntlobo zeentlekele, iYunivesithi yaseStanford iphuhlise iisenzi ezidityaniswe kunxibelelwano lwefibre optic ukuze uthungelwano olubanzi lweesismografi kuzo zonke ezo ndawo apho ifayibha yokukhanya ifumaneka , ukwazi ngalo lonke ixesha okwenzekayo emhlabeni.
Iirigs zeoyile zisebenzisa inkqubo efanayo ukukhangela naluphi na uhlobo lokungcangcazela olunokuchaphazela kungekuphela nje kumthombo abawumbayo kodwa nokuthembeka kweqonga lonke. Ngokwemvelo, ifayibha yokukhanya ibuthathaka kakhulu kukungcangcazela, ke nakuphi na ukwahluka kubume bayo okanye ukungcangcazela kubangela umahluko onokurekhodwa ukufumanisa ukuba siyintoni na isizathu esiphazamise okanye esigqwethe umqondiso kwaye sizame ukusombulula ingxaki.
Ngo-Septemba ngo-2016, iYunivesithi yaseStanford yafaka inethiwekhi ye-fiber optic ephantse ibe ziikhilomitha ezi-5, eyayixhotyiswe ngabenzi boluvo abanakho ukubona naluphi na uhlobo lokuhamba, nokuba kuncinci kangakanani. Ukusukela ngoko, ngokweYunivesithi, ibonakalise ukuba yeyona ndlela isebenzayo xa utolika naluphi na uhlobo lokuhamba komhlaba, enyanisweni ukuza kuthi ga ngoku, ikwazile ukurekhoda iminyhadala eyahlukeneyo engama-800. Ngapha koko, olu vavanyo lukwazile ukubona inyikima enobunzima obungu-8,2 obabetha iMexico ebutsheni bangoSeptemba, nangona bohlulwe ngaphezulu kweekhilomitha ezingama-3.000, kodwa ke, kwakukude kakhulu ukunika isiginali.
