Geologists siv seismic nthwv dej txhawm rau nrhiav qhov chaw av qeeg qhov chaw, ntsuas qhov sib txawv ntawm lub sijhawm tuaj txog ntawm P nthwv dej thiab S nthwv dej.
geologists nrhiav qhov chaw nruab nrab ntawm av qeeg li cas?
geologists nrhiav qhov chaw ntawm av qeeg li cas? Geologists ntsuas qhov sib txawv ntawm lub sijhawm tuaj txog ntawm P nthwv dej thiab S nthwv dej nrog peb lossis ntau dua seismographs Lawv pom qhov kev ncua deb ntawm lub epicenter los ntawm txhua qhov seismograph thiab npaj qhov kev ncua deb li lub voj voog ntawm daim ntawv qhia siv qhov sib txawv.
Koj pom qhov chaw nyob li cas?
ntsuas qhov sib txawv ntawm lub sijhawm tuaj txog ntawm thawj shear (s) nthwv dej thiab thawj compressional (p) nthwv dej, uas tuaj yeem txhais los ntawm seismogram. Mua qhov sib txawv los ntawm 8.4 txhawm rau kwv yees qhov deb, hauv mais, ntawm qhov chaw nres tsheb seismograph mus rau qhov chaw epicenter.
Yuav ua li cas thiaj nrhiav tau qhov chaw ntawm av qeeg?
Siv lub sijhawm S-P lub sijhawm, txiav txim siab qhov kev ncua deb ntawm txhua qhov chaw nres tsheb rau av qeeg siv lub sijhawm mus ncig. Siv daim duab qhia chaw thiab cov duab kos duab kos duab kos duab ntawm radii sib npaug rau qhov chaw nruab nrab ntawm txhua qhov chaw nres tsheb. Qhov twg cov arcs sib tshooj, koj tuaj yeem kwv yees koj qhov chaw epicenter.
Koj nrhiav qhov chaw nruab nrab ntawm av qeeg siv txoj kev triangulation li cas?
Triangulation tuaj yeem siv los nrhiav qhov av qeeg. Cov seismometers tau pom tias yog ntsuab dots. Qhov kev ncua deb ntawm txhua qhov seismometer mus rau av qeeg yog qhia raws li lub voj voog. Qhov chaw uas txhua lub voj voog hla yog qhov chaw ntawm qhov chaw av qeeg.
