Kukho utshintsho olufihlakeleyo ngaphambi kwenyikima ukuba izilwanyana ezininzi ziyakwazi ukubona. Kuyinyani ukuba kukwakho namabali malunga neenyoka ezishiya imingxunya yazo, izinja ezikhonkotha kakhulu okanye iintaka ezibhabha iintsuku okanye iiveki phambi kokuba zenzeke. Kwezi meko kuyaphikiswa ngakumbi ukuba ezi ndlela zokuziphatha zenzeka. Kodwa inyani kukuba izilwanyana ezininzi ziyakwazi ukubona iinyikima, ixesha ngaphambi kokuba zenzeke.
Xa inyikima isenzeka, iinyikima zihamba emhlabeni ngendlela esingayiqondiyo. Nangona kunjalo, olu hlobo lokungcangcazela, olona luhamba phambili, luhamba kabini isantya sezizisekondari, ezibangela wonke umonakalo. Ezinye izilwanyana, ezinako ukuzenza, kukufumana ukungcangcazela okuphambili ngaphambi kokufika kwesekondari. Eli xesha lokuphumla, ubuncinci lemizuzu emibini, libanika ithuba lokuphendula ngaphambi kokufika kwengxolo enkulu.
Ubungqina besayensi
Isifundo esivela kwiYunivesithi evulekileyo e-UK sifumene ubungqina. Uxinzelelo olwakhayo kuyo yonke Imigca yenyikima ikhupha amasuntswana afakwe ngombane. Ezi zidluliselwa ngamatye, zivelisa utshintsho lweekhemikhali kumanzi angaphantsi komhlaba. Kule meko, ewe Inokuqondwa into yokuba amakhoba ashiye amachibi abo ngequbuliso. Umzekelo olungileyo woku iya kuba yinyikima e-L'Aquila ngo-2009, e-Itali. Isiziba apho kufunyanwa khona oosomaqengqele bekukho i-74km ukusuka kwindawo eyintsusa yenyikima. Inyikima ibingu-6,3 kwisikali sikaRichter, yaze yadala nomonakalo omkhulu, phakathi kwezindlu ezininzi kutshatyalaliswe kwaphela.
Olunye uqikelelo olunokubangelwa kukufaniswa nale nto ichaziweyo kukuziphatha kweentaka namalulwane. Kungenzeka ukuba Iindleko ezintle zinefuthe kumabala ombane athi amalulwane neentaka asebenzise kuwo ukuziqhelanisa. Kodwa akukho khonkco lithe ngqo eliqinisekisiweyo okwangoku. Ke okwangoku, ezona zinto zibambekayo zihlala ziintshukumisa eziphambili ezinokuqondwa zizilwanyana ezininzi. Esi sizathu sesayensi sokuba kutheni basabele ngaphambi kokuba inyikima enamandla ihlasele.
