Ibinyamanswa byabanjirije amateka ntibigenzurwa kubera inyanja yabyo. Gusa imanza nke zizwi mugihe izo ngero zafashwe ari muzima. Ubushize ibi bibaye muri Mutarama 2007. Hafi yubwato bwumurobyi wumuyapani, hagaragaye ikintu atigeze abona mbere. Umurobyi yagejeje ku byo yabonye ku buyobozi bwa Parike ya Awashima (Ikirwa cya Honshu, Umujyi wa Shizuoka). Abayapani ntibafashe gusa, ahubwo bafotoye iyi nyamaswa. Ifi yari ifite uburebure bwa m 1,6, iranyeganyega nka eel. Yabaze amenyo 300, mumirongo 25. Inyanja yafunitse yashyizwe mu kidendezi cy’amazi yo mu nyanja, ariko ipfa nyuma yamasaha make. Birashoboka cyane ko indwara yamuteye kuzamuka mu nyanja. Hasigaye gusa kubaka hypotheses kuriyi.

Inyanja yuzuye ntagaciro ifite mubucuruzi, kuko ni gake cyane. Kandi buri teraniro rye numuntu nibintu byose (kumuntu, birumvikana). Kenshi na kenshi, "amatariki" ni impanuka. Abantu bashiraho inshundura zo hasi kugirango bafate urusenda. Kandi bakuramo inshundura, babona imyenda gusa, nuko abarobyi b'Abayapani babona ko ari udukoko.

Vuba aha, umubare winama yabantu bambaye abantu bariyongereye. Ariko abahanga bakunda kwizera ko ibyo biterwa no kuzamuka kwubushyuhe bwinyanja, ntabwo biterwa no kwiyongeraumubare w'izo nyamaswa. Nta mwuka uhagije uri ku nyanja, kandi ibinyabuzima byabanjirije amateka yabitswe bihatirwa gushaka aho bitura. Muri 2012 rero, abarobyi ba Murmansk bakuyemo gufata "amateka". Mu mazi yinyanja ya Barents, bahuye nabahagarariye kera cyane ba shitingi.
