<prompt> Pfupisa nyaya yacho: Masayendisiti anenge ane chokwadi chokuti California ichadengenyeka nokudengenyeka kwakasimba mumakore 30 anotevera. Zvino vanoti ngozi yokudengenyeka kukuru ingangova yakakura kupfuura zvaifungidzirwa kare. Mikana yokudengenyeka kwenyika kwakakura 8 kunorova nyika yacho mumakumi matatu emakore anotevera yakasvetuka kubva pa4,7 muzana kusvika pa7 muzana, zvikurukuru nemhaka yokuti masayendisiti akafunga nezvokugona kwokuti zvikanganiso zvinoverengeka zvinogona kudengenyeka panguva imwe chete, zvichibudisa simba rinokanganisa rinoguma nokuparadza kukuru. Nepo ngozi yokudengenyeka kwenyika kukuru iri yakakwirira kupfuura kufungidzira kwekare, kunobvira zvikuru - mikana inopfuura 99 muzana - kuti California ichadengenyeka nokudengenyeka kukuru kwakakura 6.7 kwakaenzana nowenjodzi yeNorthridge ya1994. Brace: Mushumo mutsva weU.S. Geological Survey wakawedzera bviro yokudengenyeka kwepasi kwakakura 8 kuchirova California mumakore 30 anotevera. Pamusoro apa, mufananidzo webhiriji rakakoromoka pakudengenyeka kwenyika kwakaitika muna 1994 kuNorthridge. Mukana wokudengenyeka kwenyika kwakakura seNorthridge wakanga uri mukuru zvishoma muNorth California kupfuura muSouthern California - 95 muzana zvichienzaniswa ne93 muzana, maererano nomushumo wakabudiswa neChipiri neU.S. Geological Survey. California inyika inodengenyeka, uye vagari vanofanira kurarama zuva rimwe nerimwe sokunge kuti izuva reimwe huru, akadaro Ned Field, nyanzvi yeGeophysics yeUSGS uye munyori mukuru. Kuverengwa kwenyikadzimu kwazvino uno kunonyatsoratidza zvakawanikwa neUSGS muna 2008. Kare ikako, masayendisiti akaonawo kuti California yakanga yakatarisana nengozi chaiyo yokurohwa nokudengenyeka kwenyika kwakakura seNorthridge. Mushumo mutsva wacho waibatanidza nzvimbo dzakaputsika dzichangobva kuwanwa uye bviro yokuti kudengenyeka kwapasi kunogona kusvetuka kubva pakuputsika kuenda kuputsika. Nemhaka yezivo iyi, mikana yokudengenyeka kwenyika kunoparadza - kwakakura 8 kana kupfuura - mumakore 30 anotevera yakawedzera. Pane mukana we93 muzana wekuti dutu rine ukuru hwe7 kana kupfuura riitike munguva imwe cheteyo uye mukana we48 muzana wekuti rine ukuru hwe7.5 - zvakafanana nokufungidzira kwakapfuura. Zviuru zvezvinodengenyeka gore rimwe nerimwe zvinorova California, yakamiswa pakati pemaplate maviri makuru epasi, Pacific neNorth...  <response>: Mushumo mutsva weU.S. Geological Survey unowedzera mikana yokudengenyeka kwepasi kwakakura 8 mumakumi matatu emakore anotevera kusvika ku7 muzana, kubva pa4.7 muzana.
