Base isolators at the base of the building absorb seismic waves and prevent the waves from traveling through the building. Steel cross braces counteract pressure that pushes ...

A ubiquitous lowvelocity layer at the base of the mantle transition zone
... We slant-stacked receiver functions as a function of time and slowness (Figures 2c and 2d). The slant-stack technique [Schultz and Claerbout, 1978] can determine the slowness of the converted phases, thus separating the primary conversions from the multiples. The maxima in the positive slowness rang ...
