Mu 1969, ogwira ntchito yomanga ku Oklahoma, m’dziko la United States, anapeza nyumba yachilendo imene inkaoneka ngati yomangidwa ndi anthu, ndipo malinga ndi kunena kwa olemba ambiri, inali ndi kuthekera kolembanso osati mbiri ya United States yokha komanso mbiri ya dziko lonse lapansi.
Kapangidwe kameneka, kamene kamafanana ndi pansi pamiyala yamiyala, kanapezeka m’nsanjika imene akatswiri amakhulupirira kuti inayamba zaka 200. Panthawi imodzimodziyo, ambiri amaganiza kuti anthu oyambirira anafika ku North America zaka 22-19 zapitazo.
Atangotulukira, nkhani yofotokoza zinthu zodabwitsazi inasindikizidwa m’nyuzipepala "Oklahoman" kudzetsa mkangano waukulu pakati pa akatswiri ndi owerenga tsiku ndi tsiku. Nkhaniyi inalinso ndi zithunzi zitatu zakuda ndi zoyera za izi "mosaic", zomwe zikadali zithunzi zokha zomwe zatsala za chinthu ichi.
Nazi zomwe zidalembedwa m'nkhani yankhani:
“Pa June 27, 1969, antchito akudula mwala womwe uli pa Broadway Extension pa 122nd Street, pakati pa Edmond ndi Oklahoma City, anapeza chinthu chimene chinayambitsa mkangano waukulu pakati pa akatswiri. …
Ndikukhulupirira kuti inapangidwa ndi anthu chifukwa miyalayo inasanjidwa bwino lomwe mizere yofananira yomwe inkadutsana kupanga mawonekedwe a diamondi, onse akuloza kum’maŵa,” anatero Durwood Pate, katswiri wa sayansi ya nthaka ku Oklahoma City amene anafufuza nkhaniyi ndi kuikamo mosamala kwambiri.
Tidapezanso dzenje la mtengo (mzati) womwe ndi wafulati. Pamwamba pa miyalayi ndi yosalala kwambiri, ndipo ngati mutanyamula imodzi mwa izo, mumapeza chinachake chomwe chimasonyeza kuvala pamwamba. Chilichonse chili m'malo abwino kwambiri kuti chitha kupangidwa mwachilengedwe. ”
Dr. Robert Bell, katswiri wofukula za m’mabwinja wa pa yunivesite ya Oklahoma, anatsutsa zimenezo, ponena kuti zimene anapezazo zinali kupangidwa mwachibadwa. Dr. Bell adanena kuti sanapeze chizindikiro cha wothandizira. Pate, kumbali ina, adapeza china chake ngati grout - madzi owundana omwe amagwiritsidwa ntchito kudzaza mipata yomanga - pakati pa mwala uliwonse.
Malinga ndi zimene ananena Delbert Smith, katswiri wa sayansi ya nthaka komanso pulezidenti wa Oklahoma Seismograph Company, komanso pulezidenti wakale wa Oklahoma City Geophysical Society. Palibe kukaikira za izo. Zinayikidwa bwino pamenepo, koma sindikudziwa kuti ndi ndani akanachita izi, " adatero mtolankhani.
Akatswiri a sayansi ya nthaka Delbert Smith ndi Durwood Pate anapita kumalowa kuti akafufuze mapangidwe ndi kutolera zitsanzo, malinga ndi nyuzipepala. "Ndikukhulupirira kuti uku sikupangidwa kwachilengedwe, koma ndi chinthu chopangidwa ndi manja a munthu," Smith anatero pambuyo pake.
Patapita masiku awiri, pa June 29, 1969, nkhani ina yofotokoza zimene anapezayi inatuluka m’nyuzipepala "Dziko la Tulsa". Kumeneko mawu a Delbert Smith anaperekedwa molondola kwambiri ndipo chibwenzi cha chinthucho chinamveka kwa nthawi yoyamba:
"Palibe kukaikira za izo. Idaikidwa mwapadera ndi winawake, koma sindikudziwa amene adayipanga. ”
“Chinthu chinanso chachinsinsi n’chokhudzana ndi chibwenzi. Pali malingaliro osiyanasiyana pankhani ya geology, koma kuyerekezera kolondola kwambiri kwa zaka za matailosi amenewa ndi zaka 200.”
Kafukufukuyu anapitiriza. Kupezeka kwa dzenje lachiwiri mu "mosaic" inanenedwa mu The Oklahoman pa July 1, 1969. Malinga ndi zotsatira za miyeso, pali mtunda wa mamita asanu pakati pa mabowo awiriwo. Malinga ndi a Pate, mwala womwe umagwiritsidwa ntchito popanga mosaic ndi kuphatikiza kwa miyala yamchere ya Permian ndi njere za quartz.
Pa July 3, nyuzipepala ya The Oklahoman inapitiriza kufotokoza za zimene apezazo, ndipo inanena kuti malinga ndi malipoti ochokera kwa akatswiri ofukula zinthu zakale. “nyundo yamwala yakale” idapezekanso pamalopo.
"Chinsinsi cha mapangidwe a miyala ya miyala ya dolomite omwe adapezeka pakati pa Oklahoma City ndi Edmond chidakula Lachitatu ndi kupezeka kwa chinthu chonga nyundo pamalopo."
Akatswiri a sayansi ya nthaka amene anatchera khutu ku mapangidwe achilendowo anapeza kukhala kovuta kufotokoza chiyambi cha mapangidwe kapena zinthuzo. John M. Ware, katswiri wa geologist ku Oklahoma City, anati: "Sizingafotokozedwe molingana ndi geology - tikufuna katswiri wofukula mabwinja kuti apereke lingaliro lomaliza. Komabe, zaka zake ndi chiyambi chake zingakhalebe zosamvetsetseka ngati wofukula za m’mabwinja sangathe kum’khutiritsa kuti ayambe ntchitoyo posachedwa.”
“Pasanathe masiku 20, omangawo apitiriza ntchito yofukula malowa kuti ayambe ntchito yosungiramo chakudya. Chinthu chinanso chochititsa chidwi cha thanthweli n’chakuti lili ndi matope a m’nyanja, kusonyeza kuti poyamba linali pansi pa nyanja.”
Pate anawonjezera kuti "Mapangidwe a 100-by-60-foot akukhala okopa alendo."
“Anthu amakhamukira kumeneko n’kuthyola miyala. Tiyenera kuisunga mpaka zitachitika kuti tidziwe komwe idachokera. ”
Tsoka ilo, zidziwitso zochepa zopezeka modabwitsazi zidanenedwa mu media ku Oklahoma pambuyo pake, ndipo zomwe zidachitika sizikudziwika mpaka pano.
