“…When available, we include earthquake magnitude. For our area, only the magnitude Mw ~6.3 of the 1927 AD event was recorded 43 . The magnitude Mw ~6.3 is smaller than the magnitude that would be derived from the scaling laws using the rupture length associated to the 1927 event.…”

Temporal distribution of earthquakes is key to seismic hazard assessment. However, for most fault systems shortness of large earthquake catalogues makes this assessment difficult. Its unique long earthquake record makes the Dead Sea fault (DSF) exceptional to test earthquake behaviour models. A paleoseismological trench along the southern section of the DSF, revealed twelve surface-rupturing earthquakes during the last 8000 years, of which many correlate with past earthquakes reported in historical chronicles. These data allowed us building a rupture scenario for this area, which includes timing and rupture length for all significant earthquakes during the last two millenaries. Extending this rupture scenario to the entire DSF south of Lebanon, we were able to confirm the temporal-clustering hypothesis. Using rupture length and scaling laws, we have estimated average co-seismic slip for each past earthquake. The cumulated slip was then balanced with long-term tectonic loading to estimate the slip deficit for this part of DSF over the last 1600 years. The seismic-slip budget shows that the slip deficit is similarly high along the fault with a minimum of 2 meters, which suggests that an earthquake cluster might happen over the entire region in the near future.

“…On 11 July 1927, at approximately 3:00 p.m. (local time), a strong earthquake affected Mandatory Palestine in its entirety, resulting in several hundred fatalities, about a thousand injured casualties, and considerable damage to cities and villages [36]. The magnitude (size) was determined to be M6.2 and the epicenter (focus) was located to the north of the Dead Sea [37,38] (Figure 1). The wealth of information regarding this event includes professional reports [39][40][41][42], popular sources and newspapers [43][44][45][46][47][48], letters, documents, accounts [49,50], and photographs [51,52] as well as scientific studies [53][54][55][56][57][58][59][60].…”

The evaluation of earthquake damage is central to assessing its severity and damage characteristics. However, the methods of assessment encounter difficulties concerning the subjective judgments and interpretation of the evaluators. Thus, it is mainly geologists, seismologists, and engineers who perform this exhausting task. Here, we explore whether an evaluation made by semiskilled people and by the crowd is equivalent to the experts’ opinions and, thus, can be harnessed as part of the process. Therefore, we conducted surveys in which a cohort of graduate students studying natural hazards (n = 44) and an online crowd (n = 610) were asked to evaluate the level of severity of earthquake damage. The two outcome datasets were then compared with the evaluation made by two of the present authors, who are considered experts in the field. Interestingly, the evaluations of both the semiskilled cohort and the crowd were found to be fairly similar to those of the experts, thus suggesting that they can provide an interpretation close enough to an expert’s opinion on the severity level of earthquake damage. Such an understanding may indicate that although our analysis is preliminary and requires more case studies for this to be verified, there is vast potential encapsulated in crowd-sourced opinion on simple earthquake-related damage, especially if a large amount of data is to be handled.

“…The Stylite Tower at Umm ar−Rasas was heavily damaged by a strong earthquake occurred in 759 A.D., which caused the fall of the covering (dome and vaulted roof) and the upper part of the structure. The most recent destructive seismic event that affected the area was the Jericho earthquake, occurred on July 11 th , 1927 (Ml = 6.2), which caused heavy damage in the close cities of Salt and Amman and probably also to the Stylite Tower [Avni, 1999;Zohar and Marco, 2012]. According to the Jordan seismic map ( Figure 6) the area is characterized by high seismicity with a Peak Ground Acceleration of 0.2g and a shear waves velocity Vs = 760 ÷1500 m/s, typical of rigid soil [Menahem, 1991;Thomas et al, 2007].…”

The stability and vulnerability analyses carried out on the Stylite tower at Umm ar−Rasas, Jordan, are presented in this paper. The tower is a unique example of this kind of structure still existing. The soil and the structural material were analyzed by means of in situ ex− perimental tests. These consisted of Schmidt−hammer tests on stone blocks and passive seismic measurements. The stability of the tower was first analyzed, assuming an elastic-perfect plastic behavior in compression for masonry. Then the push−over seismic analysis was carried out, which was based on a single−mode approach and a finite solid element modelling with a Drucker−Prager yield criterion for masonry. The work is propaedeutic to the design of a retrofit intervention.
