Our largest mesh has $\approx$261 billion degrees of freedom, resolving at least 15 Hz of the acoustic wave field. Multi-petascale simulations, with excellent performance demonstrated on three different platforms, allow high-resolution forward modeling. We present a highly scalable 3D fully-coupled Earth
