While commonly plotted as points on maps, earthquakes of this size involve slip over a large fault area that can be hundreds of kilometers long, depending on the earthquake size. USGS scientists used both comparisons of pre- and post-event satellite imagery and manual mapping methods to identify the extent of the earthquake fault rupture. This information has been published as a GIS map and data portal online. The preliminary analyses suggest a surface rupture length of approximately 460 kilometers (290 miles), agreeing well with updated estimates from USGS slip models derived from analysis of global seismic data.
