The countries surrounding the gulf (Egypt, Israel, Jordan, and Saudi Arabia) operate their own seismic networks and during the months that followed the main event, fourteen temporary and permanent stations recorded thousands of aftershocks. Klinger acquired data on approximately 1,000 aftershocks via the European-Mediterranean Seismological Center and the agencies of each country. The data was filtered to include only those aftershocks within of the epicenter. Data from four stations from the Institute for Petroleum Research and Geophysics of Israel plus seven stations from Jordan's Natural Resource Authority recorded aftershocks in the epicentral area that met the restriction. It was found that the aftershocks were arranged with a north-south alignment over a length of and that was expected from an earthquake of such magnitude. The group of aftershocks were bunched in two distinct clusters, with one in the north and one further south.
