Ground subsidence in urban areas due to excessive development and degraded underground facilities is a serious problem. Geophysical surveys have been conducted to estimate the distribution and scale of cavities and subsidence. In this study, electric

We propose an alternative strategy for overcoming the high sensitivity of the Laplace-domain waveform inversion to early time noises, especially of deepwater seismic data. We estimate the source wavelet from the raw direct wave using the full Newton

Waveform inversion in the Laplace domain has the advantage of finding a smooth velocity structure including salt domes having a large velocity contrast to the background medium. In exploration, noises contaminate the data before and near the direct w
