Seismic Waves and Analysis

Seismic Waves and Analysis is a research topic within Geophysics. Science Explorer counts 53k research works in it since 1950. 10.5% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the high-resolution tomographic imaging of the Earth's subsurface using ambient seismic noise, particularly surface wave tomography and the extraction of Green's functions. It encompasses techniques such as seismic interferometry, cross-correlation of noise data, and distributed acoustic sensing for monitoring seismic events and subsurface structures. The research also explores applications in characterizing near-surface geological features and monitoring changes in seismic velocity over time.
