Abstract

Seismic wave propagation is intrinsically a process in time and space. Although seismometers make point measurements only, dense, large‐aperture seismic networks allow the full observation and analysis of wave propagation. We present a new visual representation of teleseismic phases by combining time‐dependent ground‐motion visualizations with array analyses to connect the time‐domain motion with phase information retrieved from the frequency–wavenumber (fk) domain. This serves as an educational tool, but also for efficient identification of off‐angle arrivals, dispersion, and anomalous seismic phases. The processing is applied to events with Mw7 observed at the AlpArray Seismic Network in Europe and two example teleseismic events are discussed in detail.
