Posachedwapa, zidapezeka kuti zingwe wamba za fiber optic zimatha kugwira ntchito ngati masensa a seismic. Kugwedezeka mu kutumphuka kwa dziko kumakhudza chingwe chomwe chimayikidwa pamalo ochitirako zinthu ndipo kumapangitsa kuti pakhale kusiyana kwa kuchuluka kwa kuwala kwa kuwala mumayendedwe a mafunde. Zipangizozi zimanyamula zopatukazi ndikuziwonetsa ngati zivomezi. Pazoyeserera zomwe zidachitika chaka chapitacho, mwachitsanzo, pogwiritsa ntchito zingwe za fiber-optic zoyikidwa pansi, zinali zotheka kulemba ngakhale masitepe a oyenda pansi.
Anaganiza kuti ayese mbali iyi ya zingwe za kuwala kuti awone momwe madzi oundana amachitira - apa ndi pamene munda sulimedwa. Madzi oundana nawonso amakhala ngati zizindikiro za kusintha kwa nyengo. Dera, kuchuluka ndi kuyenda (zolakwika) za madzi oundana akulu kwambiri padziko lapansi zimapereka chidziwitso chofunikira pakulosera kwanyengo kwanthawi yayitali komanso kulosera zakusintha kwanyengo. Choyipa chokha ndichakuti kuyang'anira madzi oundana pogwiritsa ntchito zida zachikhalidwe za zivomezi ndikokwera mtengo ndipo sikupezeka kulikonse. Kodi zingwe za fiber optic zingathandize ndi izi? Akatswiri ochokera ku Swiss Federal Institute of Technology Zurich (ETH Zurich) anayesa kuyankha funsoli.
Gulu la asayansi lotsogoleredwa ndi Andreas Fichtner, pulofesa ku Laboratory of Hydraulics, Hydrology ndi Glaciology ku ETH Zurich, anapita ku Rhone Glacier. Pakuyesaku, zidapezeka kuti zingwe za fiber optic ndizoposa zida zabwino kwambiri zojambulira zochitika za seismic. Komanso, chingwe anaika pa chisanu ndi ayezi pansi Kutentha kwa dzuwa lokha anasungunuka mu ayezi, amene mwamtheradi kofunika kuti ntchito maukonde masensa.
Maukonde opangidwa ndi masensa okhala ndi malo ojambulira ma vibration owonjezera mita imodzi motsatira utali wa chingwe adayesedwa ndi kuphulika kotsatizana koyerekeza zolakwika mu glacier. Zotsatira zopezedwa zidaposa zonse zomwe amayembekeza. Motero, asayansi posachedwapa adzakhala ndi zida zimene zingathandize kufufuza madzi oundana molondola kwambiri ndi kuchenjeza za zivomezi zikangoyamba kumene kuphulika kwa madzi oundana.
