“…While the eastern and northern regions of Iraq, which lie near the convergence borders of the Arabian and Eurasian plates, are subject to significant seismic activity, other regions of the country, which are farther from the plate boundary, are only subject to weak seismic activity [37]. The seismicity of Iraq has been studied by many researchers (for example, [38], [39], [35], [40], [41], [42], [43], [44]; [45], [46], [47], [48], Iraq is divided tectonically into three regions: the Bitlis-Zagros Fold and Thrust Belt, the Mesopotamia Foredeep, and the Inner (stable) Arabian platform (Figure 1) [52]. The Mesopotamia Foredeep is divided into the Al-Jazira Plain and the Mesopotamia Plain.…”

“…While there are faults in the Inner Arabian Platform, they have undergone far less recent deformation and show less evidence of Quaternary activity [37]. Local deformation contributes to the seismicity of a stable shelf [56]. Based on the information gathered from the International Seismological Center (ISC) by [49], Figure 1 shows the seismicity map of Iraq for 1900-2019 .…”

It has long been clear that earthquake prediction is important from both social and economic perspectives; therefore, the practical objective of today’s earthquake seismology researchers is an effective earthquake prediction program. The purpose of this study is to estimate earthquake probabilities and return periods using an updated earthquake catalogue (1900-2019) for Iraq and its surroundings. Weibull’s formula and inverse Weibull’s formula were employed to calculate the period of return and the occurrence probability of the maximum magnitude earthquake. The return period for earthquakes magnitudes 5 and 7Mw was 1.1 and 10.54 years, respectively, while the occurrence probability was 93.79% and 9.5%, respectively. The greatest magnitude is 7.7, with a 121-year return period and likelihood of approximately 0.82%. The probability of exceedance increased as the time period increased. The return duration was greater for earthquakes of higher magnitudes.

“…Important examples of long-term earthquakes and, therefore, seismic hazards are: -On December 8, 1058 earthquake with a magnitude of 6.5-7.0 in eastern Iraq [21]. -September 22, 1666, Mw-7:0 earthquake near Mosul [22]. -Earthquake December 7, 1864 MW 6:5 southeast of Iraq [23].…”

This study deals with addressing the scientific achievements and the history of earthquake prediction in Iraq, in addition to attempting to discuss the possibility of machine learning to predict earthquakes from a theoretical perspective. The idea of predicting earthquakes gives at least a little time to protect people and reduce earthquake damage. In Iraq, we notice an increase in the occurrence of earthquakes, especially in the southern regions, where they form a strange phenomenon because they are plain areas and far from the seismic fault line, due to the errors that accompany excessive oil extraction and in random and unstudied ways, and geological studies raise fears in predicting an increase in earthquakes for the coming years. We have explored the possibility of applying machine learning technology to predict earthquakes in Iraq, and follow-up recording of tremors at different stations in Iraq through three centers of seismic sensor networks. In addition to the earthquake catalog in Iraq (1900-2019). This study may pave the way for more research to develop an integrated and accurate earthquake prediction system using machine-learning technologies.

“…The deformation kind that occurs during the earthquake usually exists along with rocks fracture zones that generate faults. The seismic activity in Iraq is long and well documented, with 79 events documented as having significant and/or minor impacts on society (Alsinawi & Ghalib, 1975). Earthquakes in Iraq are more known after 1900 within the boundary of the Iraq earthquake map in with most of the shocks in the depth of the Earth's crust.…”

Earthquakes are significant natural geohazards that threaten life and property. Iraq lies in a seismically active region, and most earthquakes result from the collision of the Eurasian- Arabian plates. On Nov. 12, 2017, an earthquake with 7.3 MW shook a large area of the Zagros Belt at the Iran-Iraq border. This work aims to use the InSAR technique for emphasis on the processing and analysis of Sentinel-1 data pre and post-earthquake supported by field, geological and tectonic information to map the ground deformation and fault activity caused by the Nov.12 earthquake. The case study involves a region located at the Iraq-Iran political boundaries. The results reveal that InSAR is a powerful tool to detect ground displacement and allow positioning faults. The interferogram results show that deformation extends to an area ~ 6300 km 2 and 7000 km 2 , with a maximum line-of-sight horizontal displacement ~87 cm and ~55 cm, vertical displacement ~121 cm uplifting and ~59 cm subsidence for ascending and descending data respectively, While pre-earthquake results show clearly neither displacement nor deformation took place. According to InSAR analysis, displacement direction, fault position detection, aftershock distribution, and the general geometric fault context, the blind back-thrust fault SW-dipping steeply occurred on the Zagros Front Fault was interpreted, in addition to new minor faults ruptured on the surface and displacement on old faults were detected. Many faults derived from the geological map coincide with the results of interferometric phase maps. Most recentlydiscovered faults appear to be related to the Nov.12 earthquake.
