WebMar 7, 2016 · Sensitivity analyses, or synthetic reconstruction tests, are the most common method for assessing solution robustness in seismic tomography, and were originally introduced to investigate spatial resolution in inverse problems for which formal resolution cannot be computed due to the large model size (Spakman & Nolet 1988). They involve … Webshallow section use mainly vertically travelling seismic energy. Tomography, on the other hand, detects anomalies with significantly different velocity, but does not require sharp boundaries. Furthermore, the seismic energy used in tomography travels mainly horizontally, making its raypath geometry more favourable for detection of lateral fm 91.5 chicago
