Figure 1bDetailed map of the JVF (Jordan Valley Fault) segment between the Sea of Galilee and the Dead Sea. The segment itself is organized as six 15-km to 30-km-long right-stepping sub segments limited by 2 km to 3 km wide transpressive relay zones. The active trace of the JVF (Jordan Valley Fault) continues for a further ~10 km northward into the Sea of Galilee (SG) and ~20 km southward into the northern Dead Sea (DS). Ferry et al (2011) |

Figure 3aGeomorphology of the Jordan Valley fault. Central section of the JVF (Jordan Valley Fault) (see location on Fig. 1b), showing drainage (outlined) that is systematically left-laterally displaced at the passage of the fault. The active trace of the JVF (Jordan Valley Fault) is pointed out by the arrows. Ferry et al (2011) |

Figure 3cGeomorphology of the Ghor Kabed site from a high-resolution total station topographic survey. The eastern fault strand shows a linear and continuous geometry with a gentle slope (the steep slope visible to the north is artificial), while the western strand displays a steeper slope and a left-step geometry. Two trenches were excavated at that site: T1 on the central strand north of the depression, and T2 on the eastern strand southeast of the depression (see logs in Fig. 5). Height curve spacing is 0.25 m. Ferry et al (2011) |

Figure 5aTrench T1 shows a distributed pattern of vertical faults that may be resolved within the uppermost layers but cannot be followed through massive clay units of Lisan age. Radiocarbon dates suggest the most recent event occurred before A.D. 1490-1800. Ferry et al (2011) |

Figure 5bTrench T2 displays a main fault zone filled with breccia that have been ruptured afterward and documents the most recent event, radiocarbon dated after A.D. 560-660. Combined, these observations suggest two surface-rupturing events occurred at Ghor Kabed between A.D. 560 and A.D. 1800, which may be related to the A.D. 749 and A.D. 1033 events.

Figure 3bGeomorphology of the Tell Saidiyeh site from a high-resolution total station topographic survey (contour spacing 0.5 m). South of the archaeological tell (located —100 m to the north, see inset in Fig. 8b), the morphology displays a recent terrace strath (Qto) affected and left-laterally displaced by the fault. The southern edges (dashed lines) of streams serve as piercing points because they are less likely to be eroded than the northern ones in a left-lateral setting. Stream El flows westward along the southern edge of Qto and is displaced by 7 ± 0.5 m across the fault. Stream W2 is a beheaded remnant of El and displays 114 ± 5 m of offset. A minimum emplacement age of 22 ka for W2 yields an average slip rate of 4.9 mm/yr for that period (see text for details). Solid rectangles represent trenches T3 and T4 (see text for descriptions), which display faulting evidence for the last 17 ka. Blanked areas could not be surveyed due to the presence of agricultural and military facilities. Ferry et al (2011) |

Figure 5cThe exposure of T3 is mainly composed of Lisan sediments. A series of fine-gained colluvial and alluvial units overlays Lisan clays and provides insight on recent events. Ferry et al (2011) |

Figure 5dTrench T4 is originally a road cut that was noticeably extended and cleaned. It is oriented 45° to the fault, which widens the deformation zone. This exposure provides the bulk of the paleoseismic dataset. See text for details. Ferry et al (2011) |

Figure 5eCorrelations of stratigraphic sections of trenches. The geological formations of Lisan and Damya are common basement-bottom units for trenches. Erosion processes (tilde lines) have major effects on soft sediments, and Trench T3 shows a significant hiatus of the Damya formation. The correlation between alluvial and lacustrine deposits and the related radiocarbon dating (see also Table 1 and Fig. 7) illustrate the different recent depositional environments at trench sites.
