In this study, the waiting time, spatial distance, and migrating trend pattern ofsuccessive large earthquakes in Iran have been investigated. In order to carry outthis work, the earthquake data of Iran with M >= 4.5 (1976-2018) have beenobtained from the USGS catalog. Then, the statistical distribution of the Intereventtime, migrating distance, and directional trend of migration of successiveevents were studied using different lower magnitude thresholds. The statistical andprobability distributions of inter-event times of earthquakes were assessed andmodelled by different distribution models. Furthermore, the directional analysisof migrating trends, as well as the spatial distances of successive events withdifferent lower magnitude, was carried out. It is observed that the inter-event timedistribution of earthquakes can be quite well fitted by the Gamma distributionmodel. The results obtained also indicate a decreasing trend in spatial distancedistribution and a meaningful correlation between the directional pattern of themigrating trends of successive events and the dominant trends of the active faults ofthe region. The results of this study can be considered as an effective step to betterunderstanding the temporal-spatial pattern of seismicity in Iran and also as anattempt to achieve earthquake prediction in this country, in a regional scale.
