The early 1990s saw many interesting contributions to the field of seismic wave propagation from a variety of US researchers, even as many wave‐propagation specialists shifted their research focus away from new methods for seismogram synthesis toward data acquisition and inversion. In part, this shift was a natural consequence of the explosive growth in the amount and availability of high‐quality digital seismic data, ready to be processed with interpretation tools developed in previous decades. As a result, observational seismology has recently made dramatic contributions toward imaging global geodynamics, revealing the great variety of crustal structures, and laying the foundation for a collaborative global network of broadband seismometers to monitor earthquakes and other seismic events. However, recent observational studies have brought to light new problems in wave propagation theory, and have made some older problems more difficult to ignore.
