Abstract We conduct a joint inversion of teleseismic receiver functions and Rayleigh wave phase velocity dispersion from both ambient noise earthquakes using data 79 seismic stations in southern Africa, which is home to some the world's oldest cratons orogenic belts. The area has experienced two largest igneous activities world (the Okavango dyke swarm Bushveld mafic intrusion) thus an ideal locale for investigating continental formation evolution. resulting 3‐D shear velocities depth range...
Abstract Lithospheric structure beneath the Archean Tanzania craton and adjacent regions, including segments of East African rift system (EARS) Proterozoic–early Paleozoic orogenic belts between EARS craton, is imaged by a joint inversion receiver functions Rayleigh wave dispersion measurements derived from ambient seismic noise for shorter periods teleseismic data longer periods. Our resulting crustal thickness, VP/VS 3D shear-wave velocity model upper 120 km show clear spatial...
Abstract Using data from 186 stations belonging to the USArray Transportable Array, a three‐dimensional shear wave velocity model for southeastern United States is constructed top 180 km by joint inversion of receiver functions and Rayleigh phase dispersion computed ambient noise teleseismic earthquake data. The resulting crustal thickness Vp/Vs ( ) measurements show clear spatial correspondence with major surficial geological features. distinct low velocities observed in depth range 0–25...
The central focus of our study is to apply a computer-base sentiment analysis on twitter data the U.S.-Mexico border wall.we want be able validate results from traditional polling method and also create pointer for decision making.From results, we were show that as valid base topics such considered study.Our compared favorably with obtained by organizations who did survey issue.Also, visualize present clear picture sentiments trend.
