Izindlela Zokuzamazama Komhlaba Ekuqapheni Imvelo
Izindlela zokuzamazama komhlaba sezilokhu ziqashelwa njengendlela eyinhloko ye-geophysical yokumaka isakhiwo esingaphansi komhlaba soMhlaba. Kodwa-ke, intuthuko yazo ayisagcini ekuhlolweni kukawoyela negesi noma ezifundweni ze-tectonic. Namuhla, izindlela zokuzamazama komhlaba zibaluleke kakhulu njengamathuluzi okuqapha imvelo ngoba zingakwazi "ukuzwa" izinguquko ezenzeka ngaphansi komhlaba naseduze kobuso, ngokuvamile ngaphandle kwesidingo sokumba noma ukungenelela okukhulu. Ngokusebenzisa amagagasi anwebekayo nokudlidliza, le ndlela inikeza ulwazi mayelana nesimo somhlabathi, amatshe, amanzi angaphansi komhlaba, ngisho nemisebenzi yabantu ethinta imvelo.
Izimiso Eziyisisekelo Zezindlela Zokuzamazama Komhlaba
Empeleni, izindlela zokuzamazama komhlaba zisebenza ngokulinganisa ukusabalala kwamagagasi okudlidliza ngokusebenzisa indawo yomhlaba. Lawa magagasi angavela emithonjeni yokwenziwa (ukuzamazama komhlaba okusebenzayo) njengezando, ukuqhuma okuncane, noma i-vibroseis, noma imithombo yemvelo kanye nomsebenzi womuntu (ukuzamazama komhlaba okungenzi lutho) njengokuzamazama komhlaba, ukuzamazama komhlaba okuncane, amagagasi olwandle, ithrafikhi, kanye nemishini yezimboni. Amagagasi akhula abhekana nokukhanya, ukujikijela, ukuhlakazeka, kanye nokushintsha kwejubane lapho edlula ezintweni ezinezakhiwo ezihlukile zomzimba. Izinzwa zokuzamazama komhlaba ezifana nama-geophone noma ama-seismometers bese ziqopha lezi zimpawu ukuze zicutshungulwe zibe ulwazi olungaphansi komhlaba.
Imingcele ebalulekile ebonwe ifaka phakathi ijubane le-P-wave (compression) kanye ne-S-wave (shear), ukuncishiswa (ukuncipha kwamandla), kanye nezici ze-spectral zesignali. Izinguquko kulezi mingcele zivame ukuhlobana nezinguquko zemvelo—isibonelo, amazinga aphakeme angaphansi komhlaba, ukuqhekeka kwamadwala, ukwehla komhlaba, noma ukunyakaza komhlabathi emithambekeni.
Izindlela Zokuzamazama Ezisebenzayo Zemvelo
Izindlela ezisebenzayo zokuzamazama komhlaba ziwusizo lapho kudingeka isinqumo esiphezulu endaweni encane, isibonelo, ukumaka izendlalelo ezingajulile ziye ekujuleni kwamashumi noma amakhulu amamitha. Amasu avamile afaka phakathi ukujiya kwe-seismic kanye nokubonakaliswa kwe-shallow seismic. Ukujiya kwe-seismic kusebenza kahle ekunqumeni ukujula kwedwala, ukujiya kwenhlabathi okugugile, noma izindawo ezibuthakathaka ezivame ukuguguleka komhlaba. Ukubonakaliswa kwe-shallow seismic, ngakolunye uhlangothi, kungenza imephu yezendlalelo ze-sedimentary, amaphutha angajulile, noma izakhiwo ezilawula ukugeleza kwamanzi angaphansi komhlaba.
Uma kukhulunywa ngokuqapha imvelo, ucwaningo olusebenzayo lokuzamazama komhlaba luvame ukusetshenziswa ukuze:
