“…For instance, Harbi et al [51] performed a clear and comprehensive analysis of the historical seismicity, proposing the re-appraisal of several historical events located in the region. On the other hand, recent instrumental seismicity recorded by the Algerian seismic network has also been the subject of several works [58][59][60][61][62]. Figure 1c depicts the shallow depth (h ≤ 30 km) focal mechanism data compiled in the region [44,45]; the Frohlich diagram [63] is displayed, and the Zoback classification [64] is used.…”

Earthquake Magnitude and Frequency Forecasting in Northeastern Algeria using Time Series Analysis

This study uses two different time series forecasting approaches (parametric and non-parametric) to assess a frequency and magnitude forecasting of earthquakes above Mw 4.0 in Northeastern Algeria. The Autoregressive Integrated Moving Average (ARIMA) model encompasses the parametric approach, while the non-parametric method employs the Singular Spectrum Analysis (SSA) approach. The ARIMA and SSA models were then used to train and forecast the annual number of earthquakes and annual maximum magnitude events occurring in Northeastern Algeria between 1910 and 2019, including 287 main events larger than Mw 4.0. The SSA method is used as a forecasting algorithm in this case, and the results are compared to those obtained by the ARIMA model. Based on the root mean square error (RMSE) criterion, the SSA forecasting model appears to be more appropriate than the ARIMA model. The consistency between the observation and the forecast is analyzed using a statistical test in terms of the total number of events, denoted as N-test. As a result, the findings indicate that the annual maximum magnitude in Northeastern Algeria between 2020 and 2030 will range from Mw 4.8 to Mw 5.1, while between four and six events with a magnitude of at least Mw 4.0 will occur annually.

“…Inside this plain, the most known and studied-one is the Guelma Neogenic intra-mountainous basin, “pull-apart” type, which is tectonically very active ( Harbi et al., 1999 ; Yelles-Chaouche et al., 2006 ). It is delimited by faults' borders (Bouchegouf and Hammam N’baïlis faults) which generated a seismic event such as 21/12/1980 Ms = 5.2, 19/01/1997 Ms = 4.0 and 26/09/2003 Ms = 4.8 ( Harbi and Maouche, 2009 ; Bendjama et al., 2021 ). These faults might be related to the hydrothermal activity in the region ( Maouche et al., 2013 ).…”
