The site effect of coda waves for four types of basement under 6 stations was studied by using the local earthquakes from digital seismograph network of West Yunnan Experimental Site.
Based on the long period surface wave data recorded by the China Digital Seismograph Network (CDSN), theQR of fundamental mode Rayleigh wave with periods from 10 s to 146 s is determined for the eastern Sino-Korean paraplatform in this paper.
The long-period recordings of the main shock from China Digital Seismograph Network (CD-SN) are deconvolved for the source time functions by the correspondent recordings of the three aftershocks as empirical Green's functions (EGFs).
The estimates show that, in the frequency range from 0.003 to 30 Hz used in broadband bottom seismology, the effect of the mass of the seismometer on the results of recording on a soft bottom is negligible.
However, the obtained spatial distribution of sources of microearthquakes and weak earthquakes is insufficiently reliable owing to the low aperture of the observation network of bottom seismographs.
More reliable data on the position and parameters of the seismofocal layer could be obtained by the observation network with a wider spread of bottom seismographs (up to 50-100 km).
Enacting these conflicts means offering a solution, and in doing so films refer to moral values and - at the same time - function as seismographs for the social relevance of bioethical topics.
We have examined shear-wave splitting in teleseismic waves (SKS) recorded on 20 seismographs deployed on a profile that followed the Southern Tibet highway during the 1992 Sino-French seismic experiment.
2312 P and some S arrival times were picked from 80 earthquakes recorded by 51 seismographs deployed on a profile that followed the southern Tibetan highway during 1992 Sino-French seismic experiment.
