Applications and limitations of DAS in shallow seismic surveys

What is it about?

We test DAS capabilities in various shallow seismic applications, including surface-wave inversion, diving-wave tomography, and passive subsurface source location. Through comparison with traditional sensors, we analyze the inherent limitations of DAS data and suggest ways to overcome them.

Why is it important?

DAS is experiencing a growing interest in near-surface seismic applications. Understanding its potential and limitations for near-surface characterization is important for survey design, data acquisition, and processing.
