E aʻo aku nā uwea fiber optic no nā ōlaʻi a kōkua i ka nānā ʻana i nā glaciers

I kēia mau lā, ua ʻike ʻia e hiki ke hana i nā uwea fiber optic maʻamau ma ke ʻano he seismic activity sensors. ʻO nā haʻalulu i loko o ka ʻāʻī o ka honua e pili i ke kaula i waiho ʻia i loko o ka wahi hana a hoʻololi i ke ʻano o ka hoʻopuehu ʻana o ke kukui kukui i nā alakaʻi nalu. Lawe nā mea hana i kēia mau ʻokoʻa a hoʻomaopopo iā lākou he hana seismic. I nā hoʻokolohua i hana ʻia i hoʻokahi makahiki i hala, no ka laʻana, me ka hoʻohana ʻana i nā kaula fiber-optic i waiho ʻia i ka lepo, hiki ke hoʻopaʻa ʻia i nā ʻanuʻu o ka poʻe hele wāwae.

E aʻo aku nā uwea fiber optic no nā ōlaʻi a kōkua i ka nānā ʻana i nā glaciers

Ua hoʻoholo ʻia e hoʻāʻo i kēia hiʻohiʻona o nā kelepona optical e loiloi i ke ʻano o nā glaciers - ʻo ia kahi kahi i wehe ʻia ai ka māla. He mau hōʻailona o ka hoʻololi ʻana i ke aniau. ʻO ka ʻāpana, ka leo a me ka neʻe ʻana (nā hewa) o nā glaciers nui loa ma ka Honua e hāʻawi i ka ʻike waiwai no ka wānana wā lōʻihi a no ka wānana ʻana i ka hoʻoikaika ʻana i ke aniau. ʻO ka mea maikaʻi ʻole, ʻo ka nānā ʻana i nā glaciers me ka hoʻohana ʻana i nā mea hana seismic kahiko he pipiʻi a ʻaʻole loaʻa i nā wahi āpau. E kōkua anei nā uwea fiber optic i kēia? Ua ho'āʻo ka poʻe loea mai ka Swiss Federal Institute of Technology Zurich (ETH Zurich) e pane i kēia nīnau.

Ua hele kekahi pūʻulu ʻepekema i alakaʻi ʻia e Andreas Fichtner, ke kaukaʻi ma ka Laboratory of Hydraulics, Hydrology and Glaciology ma ETH Zurich, i ka Rhone Glacier. I ka wā o nā hoʻokolohua, ua ʻike ʻia he ʻoi aku ka nui o nā kaula fiber optic ma mua o nā mea hana maikaʻi loa no ka hoʻopaʻa ʻana i ka hana seismic. Eia kekahi, ʻo ke kaula i kau ʻia ma luna o ka hau a me ka hau ma lalo o ka hoʻomehana ʻana o ka lā ponoʻī i hoʻoheheʻe ʻia i loko o ka hau, he mea pono loa ia no ka hana ʻana o ia pūnaewele o nā mea ʻike.

E aʻo aku nā uwea fiber optic no nā ōlaʻi a kōkua i ka nānā ʻana i nā glaciers

Ua hoʻāʻo ʻia ka ʻupena i hana ʻia o nā mea ʻike me nā helu hoʻopaʻa haʻalulu i hoʻokahi mika wale nō ma ka lōʻihi o ke kaula me ke ʻano o nā pahū e hoʻohālikelike ana i nā hewa i loko o kahi glacier. ʻO nā hopena i loaʻa ma mua o nā manaʻo a pau. No laila, hiki koke i nā ʻepekema ke loaʻa i ko lākou mau lima nā mea hana e kōkua i ka nānā ʻana i nā glaciers me ke kiʻekiʻe kiʻekiʻe o ka pololei a me ke ao ʻana i nā ōlaʻi i ka wā mua o ka hana crustal.
