Abstract
In this study, a large seismological dataset from the Mesopotamian Network (MP) and the Iranian Seismological Center (IRSC) was analyzed to relocate earthquakes with magnitude Mw ≥ 4 for the period between August 2014 and April 2021 that occurred in the Outer Arabian Platform of Iraq. The Computer Programs in Seismology (CPS) wrer used for this purpose. The iterative method was applied to relocate earthquakes. The magnitude of these earthquakes was also calculated using MbLG. The results of relocating 222 earthquakes are presented in this study. The results show that using seismic stations from the Mesopotamian Network and the Iranian Seismological Center enhance the earthquake locations due to the good geographical distribution of stations and closer epicentral distances. In addition, using the proper velocity model is important, especially for earthquakes located in the Mesopotamia Plain.
