Sikulungele Kanjani KuLowo Omkhulu?
Ingabe i-Seattle ilungele ukuzamazama komhlaba okukhulu? Ukubonazamazama komhlaba okuphahlazekayo kanye ne-tsunami eJapane kuvaliwe ukuzamazama komhlaba okubangelwa ngo-2010 eChile, elinye izwe elicebile, elingenakuqondakala kahle, linabantu abaningi eNyakatho-ntshonalanga bezibuza ukuthi ukulungeleka komhlaba okukhulu kangakanani.
Amaphutha
I-Cascadia Fault (noma i-Cascadia subduction zone, ukusebenzisa i-term eqondile) isebenza eceleni kolwandle ukusuka enyakatho ye-Vancouver Island e-Seattle nasePortland kuya enyakatho yeKalifornia.
Ososayensi bakholelwa ukuthi leli phutha le-tectonic liyakwazi ukudala ukuzamazama komhlaba okukhulu kakhulu, ukuphonsa 9.0 esikalini saseRichter, nokuthi kukhona cishe amathuba angu-40% okwenzeka ku-mega-earthquake eminyakeni engama-50 ezayo. Okwamanje asikho indlela yokubikezela isikhathi sokuzamazama okunjalo, lowo kuphela kungenzeka kakhulu. Futhi ngenxa yokuthi iphutha lisemgodini, ukuzamazama komhlaba kweCascadia kunomthelela omkhulu wokukhiqiza i-tsunami enkulu.
Muva nje, ososayensi bathola iphutha elincane, elingajulile elihamba ngqo ngaphansi kwedolobha lase Seattle ngokwalo, elibizwa nge-Seattle Fault. Lephutha alikwazi ukudala ukuzamazama kwe-mega ngaphezu kwe-8.0 kodwa kungenza umonakalo omkhulu ku-Seattle ngenxa yokusondela kwayo. Lephutha liyingxenye yenethiwekhi yeziphambeko ezingavamile, kufaka phakathi i-Tacoma Fault ne-Olympia Fault, ngayinye ibeka izingozi zayo ezingxenyeni ezahlukene zesifunda.
Ukulimala Okungenzeka
Ukuzamazama kwe-mega ku-Cascadia iphutha kungenza i-tsunami ibe ngamamitha angu-100 phezulu.
Nakuba iningi le-Seattle liphakeme ngaphezu kwamamitha angu-100, i-wave enkulu enkulu izosula imiphakathi yasogwini futhi ibhubhise amabhuloho amaningi aphansi ahlanganisa iSttle nezwe langaphandle, okungabangela ukuhlupheka kwabantu njengoba izinkulungwane zingasala ngaphandle kokudla noma amanzi amasha izinsuku.
Ukuzamazama okunamandla kakhulu eS Seattle Fault kungaba empeleni kube yingozi kakhulu edolobheni, ngenxa yokujula okungeziwe kwephutha kanye nokusondela kwayo kwedolobha.
Ucwaningo oluthile lubikezele ukuthi ukuzamazama komhlaba okungu-7.0 kuphela eS Seattle Fault kuzobhubhisa amabhuloho angu-80 endaweni yaseMattle. Isibonelo salolu cwaningo sibalwa ukubulawa kwabangaphezu kuka-1 500 nabangu-20 000 balimala kabi. Ukulimala okukhulu kuzokwenzeka ekupheleni kwezikebhe, izindawo zokudoba, izakhiwo zehhovisi, nezibhedlela. I-Alaskan Way Viaduct eyinkimbinkimbi yayizowela kalula. Iphayiphi enkulu yephethiloli egijima emhlabathini ikakhulukazi ongaqineki e-Renton ingahle ihlukane. Izingxenye ze Seattle ezakhiwe ekuzaliseni umhlaba (Pioneer Square kanye nenqwaba yamanzi) zingabona ukubhujiswa okukhulu.
Ukulungiswa Kanjani I-Seattle?
Ngo-2010, isazi sokuzamazama komhlaba uPeter Yanev wabhala umhleli odabukisayo eNew York Times ehlanganisa iSttletle ngenxa yokuzamazama komhlaba okukhulu. Uthe umvuthwandaba ophansi wezingulube ezinkulu eNyakatho-ntshonalanga kwaholela emakhodi wokwakha amaningi akhululekile kunamadolobha afana neSan Francisco naseLos Angeles. Ngokusho kukaJanev, "imizi yasePacific Northwest ishicilelwe izakhiwo ezinamafomu ezincane nezakhiwo ezincane. Kuzamazama komhlaba, izakhiwo eziningi eziseduze zendawo zesigodi cishe zizowela. "URob Witter, i-Oregon geologist etshela i-Oregonian ukuthi," Inani lokubhujiswa ngeke libe khona.
Abantu ngeke balungele lokhu. "
Ukuzamazama komhlaba kuka-2001 kwe-Nisqually kwenzakala njengento yokuvusa iSttle, okwenza amandla okuvuselela izakhiwo nezakhiwo ezisengozini kakhulu. I-Harbourview, isikhungo esiyinhloko sendawo yokuhlukumezeka, senziwa kabusha. Iziteshi zomlilo ezintsha zakhiwe ngezinga eliphezulu lekhodi. Kodwa-ke, eminyakeni eyishumi kamuva i-Alaskan Way Viaduct isasebenza, ibhuloho elithantayo elingu-520 lisalokhu lithwele izinkulungwane zezimoto ngosuku, futhi idolobha limisa isimiso sokuvuselela izakhiwo zezitena ezindala ngo-2008. Ukuvuselela zonke izingozi ezisengozini kule ndawo kuzodola amakhulu ezigidi zamaRandi. Abanikazi bemihlaba abazimisele ukukhokhela ukulungiswa futhi ohulumeni basekhaya kanye nabendawo basuke bekhokhiswe imali. Kodwa-ke, izindleko zokulungiswa ziphansi kakhulu kunezindleko zomnotho zesitatimende se Seattle Fault, ku-ballpark ye $ 33 billion.
Yini Ongayenza?
Kunezingozi ezimbili eziyinhloko kubantu base Seattle, isikhathi esifushane nesikhathi eside. Ingozi yesikhathi esifushane ukuwa kwezakhiwo zezitini ezindala. Labo abahlala noma abasebenza kwelinye lalezi zakhiwo bangase bafune ukucubungula indawo. Ukwengeza ezinye izindawo zingasengozini kunezinye: Pioneer Square, Georgetown, ne-Interbay ziyingozi kakhulu kuneCapitol Hill, Northgate, noma iRainier Valley.
Ingozi yesikhathi eside ayiyona ingozi emzimbeni ngokushesha kodwa kungenzeka ukuthi ukuzamazama okukhulu kuzophula imigqa yamanzi futhi kunqamule imigwaqo eletha ukudla edolobheni izinsuku. Ochwepheshe batusa ukuhlanganisa isikhungo esiphuthumayo ekhaya lakho esingakusekela ngokudla, amanzi, kanye nezinto zokusiza okungenani izinsuku ezintathu. Idolobha laseSan Francisco lidale i-SF72.org enhle kakhulu eyokuqondisa ngokudala i-kit esiphuthumayo.
