At the time of its occurrence, the 1994 Northridge earthquake produced one of the most comprehensive datasets of earthquake ground motion recordings to date. In spite of this, the spatial locations of instrumental observations do not provide sufficient resolution to fully visualize many of the important ground shaking features that occurred during this earthquake.
