We present a new method and implementation (Instaseis) to store global Green's functions
in a database which allows for near-instantaneous (on the order of milliseconds) extraction …

In this work we investigate fundamentals of a method—referred to as full waveform ambient
noise inversion—that improves the resolution of tomographic images by extracting waveform …

We develop a general theory for interferometry by correlation that (i) properly accounts for
heterogeneously distributed sources of continuous or transient nature,(ii) fully incorporates …

We present a novel numerical method to simulate global seismic wave propagation in
realistic aspherical 3-D earth models across the observable frequency band of global …

Phase velocities derived from ambient-noise cross-correlation are compared with phase
velocities calculated from cross-correlations of waveform recordings of teleseismic …

We present a new, computationally efficient numerical method to simulate global seismic
wave propagation in realistic 3-D Earth models. We characterize the azimuthal dependence …

The sources of ambient seismic noise are extensively studied both to better understand their
influence on ambient noise tomography and related techniques, and to infer constraints on …

We develop and apply a novel technique to image ambient seismic noise sources. It is
based on measurements of cross-correlation asymmetry defined as the logarithmic energy …

The retrieval of a deterministic signal from recordings of a quasi-random ambient seismic
field is the central goal of noise interferometry. It is the foundation of numerous applications …

We present the first application of full‐waveform ambient noise inversion to observed
correlation functions that jointly constrains 3‐D Earth structure and heterogeneous noise …
