In this study, we present the work done to review the existing historical earthquake information of the Dead Sea Transform Fault Zone (DSTFZ). Several studies from various sources have been collected and reassessed, with the ultimate goal of creating of new homogenized parametric earthquake catalog for the region. We analyze 244 earthquakes between 31 BC and 1900, which are associated with the geographical buffer extending from 27 N to 36 N and from 31 E to 39 E. Of these, 93 were considered real seismic events with moment magnitude (Mw) greater than 5 that indeed occurred within this zone. While we relied on past parametric data and did not assign new macroseismic intensities, magnitude values, or epicenters for several controversial events, we did however resort to the primary sources to obtain a more critical perspective for the various assigned macroseismic intensities. In order to validate the derived parametric information, we tried to associate the events present in the historical records, with any evidence coming from past field investigations, i.e., geological or archaeological studies. Acknowledging the uneven quality and quantity of data reporting each event, we provided each entry with an uncertainty range estimate. Our catalog lists 33 events of Mw ≥ 6 absent from the latest published compilation with compatible time span and areal coverage. The whole catalog is considered complete down to Mw 7 and in certain areas down to Mw 6 after the year 1000, with majority of the larger earthquakes located in the part of DSTFZ, which extends from the southeast part of Dead Sea lake till Antioch.

死海变换断裂带周围历史地震的更新参数目录

在这项研究中,我们介绍已完成的工作,以回顾死海转换断层带(DSTFZ)的现有历史地震信息。收集并重新评估了来自各种来源的几项研究,最终目的是为该地区创建新的均质化参数地震目录。我们分析了公元前31年至1900年之间的244次地震,这些地震与从27 N到36 N以及从31 E到39 E的地理缓冲区有关。在这些地震中,有93次被认为是具有矩震级(M w)大于该区域内确实发生的5个。虽然我们依赖于过去的参数数据,并且没有为几个有争议的事件分配新的宏观地震烈度,震级值​​或震中,但是我们确实求助于主要来源,以获取各种宏观地震烈度的更为关键的观点。为了验证派生的参数信息,我们尝试将历史记录中存在的事件与过去田野调查(即地质或考古研究)中得到的证据进行关联。确认报告每个事件的数据的质量和数量参差不齐,我们为每个条目提供了不确定范围估计。我们的目录列出了33个M w事件≥6缺少最新发布的具有兼容时间跨度和区域覆盖范围的编辑。整个目录被认为是完整的到中号w ^ 7,并在某些领域到中号W¯¯ 1000年后6,与多数位于DSTFZ部分较大的地震,从死海湖,直到安提阿的东南部分延伸。
