Siyilungele Njani Eyona Nkulu?
Ngaba i-Seattle ilungiselele inyikima enkulu? Ukubona ukuzamazama komhlaba kunye ne-tsunami eJapan zivale kwizithende ze-2010 eziphazamisayo kwiChile, elinye ilizwe elicebileyo, elingenakulinganiswa, linabantu abaninzi eMntla-ntshona-ntshona bezibuza ukuba zilungele njani izixeko kunye needolophu.
I ziphoso
I-Cascadia Fault (okanye i-Cascadia indawo yecandelo lokutshintshwa, ukusetyenziswa kwexesha elichanekileyo) lihamba ukusuka kunxweme ukusuka kwisiqithi esiphantsi kwe-Vancouver kwisiqithi sase Seattle nasePortland ukuya enyakatho yeKalifornia.
Iingcali zenzululwazi zikholelwa ukuba le ngxaki ye-tectonic iyakwazi ukudala iinyikima ezinkulu ezinkulu, ukukhupha i-9.0 kwisikali se-Richter, kwaye kukho amathuba angama-40% oku kwenzeka kule minyaka engama-50 ezayo. Ngelo xesha akukho ndlela yokuchaza kwangaphambili ixesha lokuzamazama, nje loo nto inokwenzeka kakhulu. Kwaye ngenxa yokuba iphoso likhulile, i-Cascadia-quake-quake isithuba esinamandla sokwenza i-tsunami enkulu.
Ngoku kutshanje, izazinzulu zifumene iphoso elincinci, elingaphantsi ngqo kwisixeko sase Seattle ngokwayo, esibizwa ngokuba yi-Seattle Fault. Le ngxaki ayinakwenzeka ukuba ivelise i-mega-quake ngaphezulu kwe-8.0 kodwa ingenza umonakalo omkhulu kwi-Seattle ngenxa yokusondela kwayo. Le mposiso yinxalenye yentsebenzo yeephene ezingekho phantsi, kuquka i-Faac Tacoma kunye ne-Olimia Fault, elowo libeka izingozi zalo kwiindawo ezahlukeneyo zommandla.
Imonakalo enokwenzeka
Inyikima ye-mega kwi-Cascadia iphutha ingavelisa i-tsunami ukuya kwii-100 eziphakamileyo.
Nangona uninzi lwe-Seattle luphakanyiswe ngaphezu kweenyawo ezili-100, umtsalane omkhulu uza kusula uluntu lwamaxweme kunye nokubhubhisa amaninzi amabhuloho aphantsi ahlangene ne-Seattle kunye nehlabathi langaphandle, okubangela ukuba kubekho ingxaki yoluntu njengamawaka angasala ngaphandle kokutya okanye amanzi amnandi. iintsuku.
Ukuzamazama okungaphantsi kwe-Seattle Fault kunokuba kungonakalisa ngakumbi kwisixeko, ngenxa yobunzulu obunzulu bephuso kunye nokusondela kwayo kweso sixeko.
Olunye uphando lwaxela ukuba ukuzamazama kwama-7.0 kuphela kwi-Seattle Fault yayiza kubhubhisa amabhuloho angama-80 kwindawo yaseMattle. Umzekelo wesifundo ubalekele ukubulawa kwabangaphezu kwe-1,500 abafileyo kunye nabangama-20,000 abalimala kakhulu. Umonakalo omkhulu uza kwenzeka kwii-terminals, kumaziko e-port, izakhiwo zeofisi kunye nezibhedlele. I-shaky i-Alaskan Way Viaduct yayiza kuwela kalula. Iipayipi ezinkulu zepetroli ezihamba ngokugqithiseleyo umhlaba ongenakunqotshwa kwiRoton zingaphula. Iziqephu ze-Seattle ezakhiwe kwi-landfill (iPioneer Square kunye neninzi yamanzi) zingabona ukuphazamiseka okukhulu.
Ulungelelani I-Seattle?
Ngonyaka we-2010, ingcali yenyikima yehlabathi uPeter Yanev wabhala umhleli ohlaselayo kwi-New York Times engqinela i-Seattle ukuba ingakulungelekanga ngokukodwa ukuzamazama komhlaba. Watsho ukuba i-frequency ephantsi yeengqungquthela ezinkulu kuMntla-ntshona-ntsholongwane kukhokelela kwiikhowudi zokwakha ezikhululekile kunezixeko ezinjengeSan Francisco naseLos Angeles. Ngokutsho kukaYanev, "Izixeko zasePacific ezisentshona-ntshona zizele izakhiwo ezinezakhiwo ezincinci kunye neendonga zincinci ezincinci. Kwi-qua-quake, ezininzi zezakhiwo zezakhiwo eziphakamileyo zendawo ziza kuqubuka. "URob Witter, i-Oregon geologist watshela i-Oregonian," Isixa semonakalo siya kukhangeka.
Abantu abayi kukulungele oku. "
Inyikima ye-Nisqually ka-2001 yaba yinto ethile yokwenza i-Seattle ikhwelo, ivuselela amandla okuvuselela izakhiwo nezakhiwo ezikhuselekileyo. I-Harbourview, isikhungo esiyintloko sengozi, sasibuyiselwa. Izikhululo ezitsha zomlilo zakhiwe kwizinga eliphezulu lekhowudi. Kodwa ke, iminyaka elishumi kamva i-Alaskan Way Viaduct isasebenza, ibhuloho ejikelezayo e-520 isayithwele iinqwelo zeemoto ngemini, kwaye isixeko sagxininisa inkqubo yokuvuselela izakhiwo zitena ezindala ngo-2008. Ukuhlaziya zonke izakhiwo ezijongene nobungozi kuloo ndawo ziza kuhlawula ikhulu lezigidi zeedola. Abanikazi bemihlaba abanqweneli ukuhlawula ukulungiswa kunye noorhulumente beendawo kunye neendawo zengxowa-mali. Nangona kunjalo, iindleko zokulungiswa ziphantsi kakhulu kuneendleko zezoqoqosho ze-Seattle Fault, kwi-ballpark yeebhiliyoni ezingama-33.
Ungenzani?
Kukho iingozi ezimbini eziphambili kubantu base Seattle, ixesha elifutshane kunye nexesha elide. Umngcipheko wexesha elifutshane ukuwa kwezakhiwo zitena ezindala. Abo bahlala okanye basebenze kwenye yezi zakhiwo bangathanda ukuqwalasela utshintsho lweendawo. Ukongezelela, ezinye iindawo ezisekuhlaleni zingengozini kunabanye: uPioneer Square, iGeorgetown, kunye ne-Interbay ziyingozi kakhulu kuneCapitol Hill, Northgate, okanye eRainier Valley.
Ingozi yesikhathi eside ayikho ingozi ngokukhawuleza emzimbeni kodwa inokwenzeka ukuba inyikima enkulu iya kuphula imigca yamanzi kwaye inqunyulwe iindlela ezizisa ukutya kwisixeko iintsuku. Iingcaphephe zincoma ukudibanisa iikiti eziphuthumayo kwikhaya lakho eliza kukuxhasa ngokutya, amanzi, kunye neenkonzo zokuqala zonyango ubuncinane iintsuku ezintathu. Isixeko saseSan Francisco sakha i-SF72.org enhle kakhulu ekukhokelayo ngokudala i-kit yongxamiseko.
