Simultaneous iterative time-domain sparse deconvolution to teleseismic receiver functions

Iterative Deconvolution and Receiver-Function Estimation

We describe and apply an iterative, t ime-domain deconvolution approach to receiver-function estimation and illustrate the reliability and advantages of the technique using syntheticand observation-based examples. The iterative technique is commonly used in earthquake t ime-function studies and offers several advantages in receiver-function analysis such as intuitively stripping the largest rec...

Moho depth variation in southern California from teleseismic receiver functions

The number of broa.dband three-component seismic stations in southern California. has more tb an tripled recently. In th is study we use the teleseismic receiver function technique to determine the crustal thicknesses and Vp / Vs ratios for th ese stations and map out t he lateral variation of Moho dept h under southern California. It is shown t hat a. receiver function can provide a very good ...

Moho depth variation in Taiwan from teleseismic receiver functions

Crust and upper mantle of Kamchatka from teleseismic receiver functions

Teleseismic receiver functions (RFs) from a yearlong broadband seismological experiment in Kamchatka reveal regional variations in the Moho, anisotropy in the supra-slab mantle wedge, and, along the eastern coast, Ps converted phases from the steeply dipping slab. We analyze both radialand transverse-component RFs in bin-averaged epicentral and backazimuthal sweeps, in order to detect Ps moveou...
