Abstract
We review the fundamentals of earthquake location and document the evolution of global one-dimensional models for travel times and velocity structure. We discuss in detail the issues of location uncertainty, weighting, corrections (station, source, and path), and data quality. Nuclear monitoring concerns have brought about an increased need for improvements in global and regional seismic event location capability. Several recent studies highlight the value of utilizing information from multiple phases and global 3-D models to improve event locations. Further progress in the use of 3-D models for high-accuracy locations will require substantial efforts to improve the quality of the arrival time data used to determine the 3-D structure of the Earth.
