DOI: 10.1177/87552930231222960
Abstract: The Atlantic and Gulf Coastal Plains (CPs) are characterized by widespread accumulations of low-velocity sediments and sedimentary rock that overlay high-velocity bedrock. Geology and sediment thickness greatly influence seismic wave propagation, but current regional ground… read more here.

DOI: 10.15446/esrj.v23n2.72623
Abstract: Local variations in soil type and (to a lesser extent) topography determine seismic amplification, thereby establishing spatial patterns in the damages caused by large earthquakes, such as the two that occurred in Chiapas, Mexico on… read more here.

DOI: 10.1785/0220220359
Abstract: Site response in the Changjiang Delta in eastern China was studied using Lg Fourier amplitude spectra. We used broadband seismograms recorded at 70 stations from 62 earthquakes with magnitude (Ms) varying from 3.5 to 5.0… read more here.

DOI: 10.1785/0220250077
Abstract: Sediment thickness is a crucial measure for many seismic studies. The slow seismic velocities associated with thick sedimentary sequences can be problematic when inverting for regional tomographic images of the crust and upper-mantle structure, and… read more here.

DOI: 10.5194/nhess-24-1223-2024
Abstract: Abstract. To test whether a globally inferred sediment thickness value from geomorphological studies can be used as a proxy to predict earthquake site amplification, we derive site-amplification models from the relation between empirical amplification for… read more here.
