Possible evidence for a double crossing phase transition in D″ beneath Central America from inversion of seismic waveforms

We invert seismic body‐wave waveform data for the vertical dependence of (isotropic) shear‐velocity in the D″ layer beneath Central America, using the transverse components of relatively long period broadband waveforms (20–200 s) as data. Our models suggest that the S‐velocity increase in D″ may be ... View More
