However, the calculation of cross-correlation values between noise samples at single sensors without any time shifts leads to measures of noise coherence that correspond to only one...

Waveform data are collected by the IMS seismic network, which contains a combination of three-component seismic stations and multi-instrument seismic arrays ( Figure 1 ). For the latter, signal-to-noise ratios are enhanced through beam forming. A subset...

We performed a large‐scale test of dynamic correlation processors on an 11 TB global dataset using 25 arrays in the 1–3 Hz frequency band. The system found over 3.2 million unique signals and produced 459,747 screened detections. A very satisfying...
