This catalog includes two different parts: historical earthquakes and instrumental earthquakes. The first part of the article describes the work done on the period 31 B.C.E. to the end of the nineteenth century. Numerous studies published in the last 30 yr, devoted to pre-instrumental earthquakes in Lebanon, had not been included in any parametric earthquake catalog. A thorough and critical review of these studies was devised to check their respective interpretations of available earthquake records in terms of seismic parameters (date, location, and size) and to select for each earthquake the most reliable interpretation. The second part provides the details on the selection of instrumental solutions for the period 1900-2015 and for magnitudes >= 4. From global instrumental earthquake catalogs, we build a unified earthquake catalog for Lebanon and bordering regions. A selection scheme is applied for the choice of the best location and the best magnitude among solutions available. The number of events in the catalog is relatively small, and all earthquakes can be checked one by one. The earthquake catalog is homogenized in moment magnitude. For 89% of the events, an M-w proxy was calculated from the original magnitude, applying conversion equations. The merging of the historical and instrumental periods highlights a specificity of this zone: the instrumental seismicity (1900-2015) corresponds to a relatively quiet period for Lebanon. The historical part, covering 2000 yr, includes similar periods of quiescence, as well as much more active periods with destructive earthquakes. specialized LIBAN 066 90 6 2236-2249 2019 0895-0695 https://www.documentation.ird.fr/hor/fdi:010077204 10.1785/0220180292 0895-0695 [F B010077204] https://www.documentation.ird.fr/hor/fdi:010077204 https://www.documentation.ird.fr/intranet/publi/2019/11/010077204.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-12-12 2019-12-16 fdi:010077204 fre
