Seismicity, seismic input and site effects in the Sahel—Algiers region (North Algeria)

Seismicity of Algeria from 1365 to 2013: Maximum Observed Intensity Map (MOI2014)

“…(Benouar, 1994;Mokrane et al, 1994;Harbi, Maouche, Ousadou, et al, 2007;Harbi, Maouche, Vaccari, et al, 2007) in which significant earthquakes have occurred over the last 50 years, such as El Asnam (1954, M 6.5; 1980, M 7.3), Constantine (1985, M 6.0), and Al Hoceima (1994, M 5.8; 2004, M 6.0) (e.g., Bezzeghoud et al, 1995;Bezzeghoud and Buforn, 1999;Bounif et al, , 2004Cakir et al, 2006, Ousadou et al, 2014. However, there is no record of the intensities for the events used to draw the map in Figure 3.…”

The large Algerian earthquakes (267 A.D.-2017)

“…Many Algerian historical events have been described in the past as major events because of their important effects (Harbi, 2007, El Mrabet, 2005. However, the instrumental period demonstrates that moderate earthquakes with a magnitude no greater than 5.5 are also destructive because of the vulnerability of the buildings.…”

“…Their works were later updated by other new catalogs of Mokrane et al, (1994);Benouar (1994); Harbi et al, (2007); , 2007 and Hamdache et al (2010).…”

“…We know for example that Algiers, the capital of Algeria was repeatedly shake by important earthquakes (Harbi et al, 2007;Sebai et Bernard, 2008). For the more recent instrumental period, seismic catalogs report many damaged earthquakes (Mokrane et al, 1994, Benouar, 1994.…”

Seismicity of Eastern Algeria: a revised and extended earthquake catalogue

“…The reappraisal of historical seismicity, whose results have been used in this work (Fig. 1), represents the first steps in a larger process of analysing historical seismicity since the available Algerian and European archives are the so far main examined sources (Harbi et al 2003a(Harbi et al , 2007Sebaï and Bernard 2008;). From the catalogue (ESM Appendix), the gap in seismic events, rather related to a gap in sources, is noticeable particularly before 1850.…”
