Kev tshawb nrhiav seismic yog ib txoj hauv kev tshawb nrhiav geophysical uas siv qhov sib txawv ntawm elasticity thiab ntom ntawm cov nruab nrab hauv nruab nrab los ua cov xwm txheej thiab cov duab ntawm cov txheej txheem av qis los ntawm kev saib xyuas thiab tsom xam cov kev cai tshaj tawm ntawm seismic yoj tsim los ntawm cov av qeeg hauv cov av hauv av.
Kev tshawb nrhiav seismic yog qhov tseem ceeb tshaj plaws thiab siv tau txoj hauv kev los daws cov teeb meem ntawm kev tshawb nrhiav roj thiab roj hauv kev tshawb nrhiav geophysical. Nws yog ib qho tseem ceeb rau kev soj ntsuam cov roj thiab cov nkev ua ntej siv khoom siv. Nws tseem siv nyob rau hauv coalfield thiab engineering geological tshawb, thaj av geological tshawb fawb thiab cov kev tshawb pom zoo.
