Large-scale simulation of seismic wave motion: A review
Soil Dynamics and Earthquake Engineering, 2020 We review key ingredients that are needed for high-fidelity simulation of earthquake-generated seismic waves in large regions. Specifically, we survey existing literature on wave-discretization methods, topography effects, seismic source modeling, domain

Noise generation in the solid Earth, oceans, and atmosphere, from non-linear interacting surface gravity waves in finite depth [PDF]
, 2012 Oceanic pressure measurements, even in very deep water, and atmospheric pressure or seismic records, from anywhere on Earth, contain noise with dominant periods between 3 and 10 seconds, that is believed to be excited by ocean surface gravity waves. Most
