Pfupisa nyaya yacho:  Vanhu vanopfuura 100 000 vari kumahombekombe ekuchamhembe kwakadziva kumadokero kwePacific vari kutarisana netsunami inogona kuuraya yakafanana neyakaitika muna 2011 muJapan. Nzvero itsva inosimbisa nzvimbo dziri muWashington, Oregon neCalifornia idzo dzaizoda nguva yakawanda kuti dzibudirire kubviswa kunzvimbo dzakakwirira kana pakaitika ngwavaira yomusikirwo inotevera. Rakarangarira kuti vagari 94 872 navashandi 42 424 vanogara mukati menzvimbo dzine ngozi yetsunami dzenyika nhatu. Munjodziwo mune nzvimbo dzavose 486, nzvimbo dzokutarisira dzinotarisirwa 440 uye mabhizimisi 2.314 ane "kuvapo kwavatengi kunokosha". Dzorera pasi kuti uone vhidhiyo. Chiratidzo chenzira yokubuda mudutu re tsunami muNehalem, Oregon, imwe chete yenharaunda dzePacific Northwest dziri munzira yedutu re tsunami rinogona kuuraya iro ringave rakafanana nerakaitika muna 2011 iro rakaparadza zvikamu zveJapan. Makumi manomwe nenomwe muzana yenharaunda dziri munharaunda ine ngozi dzakashongedzerwa norudzi rwenzvimbo nenzvimbo kuti dzivabvumire maminitsi 15 kusvikira ku 25 anodikanwa nokuda kwokubviswa kunobudirira kwetsunami pashure pokunge kudengenyeka kukuru kwenyika kwaitika. Uye dzimwe nzanga dzinogona kuwedzera mikana yadzo yokupona nokungofamba nokukurumidza. Maererano nokuongorora kwacho, vagari 21 562, vanopfuura 50 muzana vavo vanogara muWashington, vaisazova nenguva yokunzvenga mafungu etsunami kudai vaifamba netsoka vachikurumidza kusvika pa1 km/h. Asi kana vakagadziridza nhanho yavo kusvika ku 3.5 mph, chiverengero chavanhu vari mungozi chinodonha pasi pe 16 000. Uye 90 muzana yevanhu 20 000 vanogara munharaunda mbiri dzine ngozi zvikurusa, Aberdeen neHoquiam muWashington, vaigona kusvika pakachengeteka nokungofamba zvishoma nezvishoma. 'Nongokuita kuti vanhu vakurumidze kufamba, unogona kuponesa zviuru zvoupenyu,' Nathan Woods, nyanzvi yeGeological Survey yeU.S. uye munyori mukuru wefundo yacho, akaudza Seattle Times. Wood akati nzanga idzi dzaizobetserwa zvikuru nokuva nechokwadi chokuti vagari vakadzidza nzira dzakanakisisa dzokupukunyuka nadzo tsunami. Asi kune mataundi ari pamhenderekedzo yegungwa asina nguva yokubuda achifamba netsoka, pasinei nokuti anofamba nokukurumidza sei kana kuti kumhanya, maererano na...
Munjodziwo nzvimbo dzavose dzinopfuura 400 nenzvimbo dzokutarisira dzinotsamira. Kudzidza kunofungidzira kuti 77% yenharaunda dzine maminitsi 15-25 anodikanwa kuti dzibve zvakachengeteka pashure pokunge kudengenyeka kwaitika. Mimwe misha muWashington, nyika ine ngozi zvikurusa, inogona kuwedzera bviro yokupona kupfurikidza bedzi nokufamba nokukurumidza. Asi dzimwe nzanga dziri pedyo nemhenderekedzo yegungwa dziri kure zvikuru nenzvimbo dzakakwirira zvokuti vanhu havagoni kubuda munzvimbo iyi - pasinei nokuti vanofamba nokukurumidza sei. Vachada kuvaka zvivako zvokubudisa vanhu panzvimbo pezvo.
