Intsinga ya fibre-optique irashobora gutanga amakarita yo hejuru-Ikarita yo munsi

Urukurikirane rw'imitingito hamwe na nyamugigima byahungabanije agace ka Ridgecrest mu majyepfo ya Kaliforuniya mu mwaka wa 2019. Ikwirakwizwa rya acoustic sensing (DAS) ukoresheje insinga za fibre optique rituma amashusho y’ubutaka ashobora gukemurwa cyane, ashobora gusobanura aho byagaragaye ko hiyongereyeho umutingito.

Ukuntu isi igenda mu gihe cy'umutingito biterwa cyane n'imiterere y'urutare n'ubutaka munsi y'ubutaka bw'isi. Ubushakashatsi bwakozwe bwerekana ko kunyeganyeza ubutaka byongerewe imbaraga mu bibaya by’imisozi, aho usanga imijyi ituwe cyane. Ariko, gufata amashusho hafi yubuso bukikije imijyi kumurongo wo hejuru byagoye.

Yang n'abandi. Bateje imbere uburyo bushya bwo gukoresha ikwirakwizwa rya acoustic sensing (DAS) kugirango wubake ishusho ihanitse yimiterere-yubuso. DAS ni tekinike igaragara ishobora guhindura ibihariinsinga ya fibre optiquemuri seisimike. Mugukurikirana impinduka zuburyo impiswi zoroheje zikwirakwira mugihe cyanyuze mumurongo, abahanga barashobora kubara impinduka ntoya mubikoresho bikikije fibre. Usibye gufata amajwi y’imitingito, DAS yerekanye akamaro mu bikorwa bitandukanye, nko kwita izina itsinda ryamamaye cyane muri Parade ya Rose 2020 ndetse no kwerekana impinduka zikomeye z’imodoka mu gihe COVID-19 yategekaga kuguma mu rugo.

Abashakashatsi babanje gusubiramo ibirometero 10 bya fibre kugira ngo bamenye imitingito nyuma y’umutingito ufite ubukana bwa 7.1 Ridgecrest muri Californiya muri Nyakanga 2019. Itsinda ryabo rya DAS ryagaragaje inshuro zigera kuri esheshatu umutingito muto nk'uko sensor zisanzwe zabikoze mu gihe cy’amezi 3.

Mu bushakashatsi bushya, abashakashatsi basesenguye amakuru y’imitingito ikomeje gukorwa n’umuhanda. Amakuru ya DAS yemereye itsinda gutezimbere hafi yubuso bwikariso yihuta hamwe na subkilometero ikemurwa ibyemezo bibiri byubunini burenze ibyitegererezo bisanzwe. Iyi moderi yerekanye ko muburebure bwa fibre, imbuga aho umutingito watanze umuvuduko mwinshi wubutaka muri rusange ugereranije n’umuvuduko wogosha wari muke.

Abanditsi bavuga ko ikarita nini y’ibishushanyo mbonera ishobora guteza imbere imicungire y’imihindagurikire y’imijyi, cyane cyane mu mijyi aho imiyoboro ya fibre optique ishobora kuba ihari.
