چکیده
The variation of some seismic properties due to energy release and accumulation specifies a change in the seismicity pattern prior to large earthquakes. Attention to the behavior of smaller events before the large already occurred earthquakes can result in the recognition of the probable seismicity pattern in susceptible future earthquake areas. The plausibility of the proposed power law model of seismicity (Gutenberg–Richter parameters) with observed seismicity data by index of p-value, can be quantitatively examined by an estimation of these effective parameters and combining them with the collected data and observed evidences in the vicinity of the epicenter. In this study, the compatibility of Gutenberg-Richter parameters and the plausibility of synthetic models in comparison with the observed seismicity before 1st December 2017, Mw 6.1, Hojedk earthquake is investigated. The results demonstrate a higher efficiency for the introduced p-value in comparison with other statistical error (σ) in different studies.

Abstract
The variation of some seismic properties due to energy release and accumulation specifies a change in the seismicity pattern prior to large earthquakes. Attention to the behavior of smaller events before the large already occurred earthquakes can result in the recognition of the probable seismicity pattern in susceptible future earthquake areas. The plausibility of the proposed power law model of seismicity (Gutenberg–Richter parameters) with observed seismicity data by index of p-value, can be quantitatively examined by an estimation of these effective parameters and combining them with the collected data and observed evidences in the vicinity of the epicenter. In this study, the compatibility of Gutenberg-Richter parameters and the plausibility of synthetic models in comparison with the observed seismicity before 1st December 2017, Mw 6.1, Hojedk earthquake is investigated. The results demonstrate a higher efficiency for the introduced p-value in comparison with other statistical error (σ) in different studies.
