“…Gravimetric studies suggest that the SoG is composed of two units (Eppelbaum et al, 2004) with the northern sector being more affected by the kinematics of the DSF. A dense‐spaced grid of seismic reflection profiles has been collected in the SoG (e.g., Gasperini et al, 2020; Hurwitz et al, 2002; Lazar et al, 2019; Reshef et al, 2007; Tibor et al, 2004). Analysis of such profiles suggest the presence of two different sets of active faults oriented N‐S and NNW‐SSE.…”

Tectonics of the Dead Sea Fault Driving the July 2018 Seismic Swarm in the Sea of Galilee (Lake Kinneret), Israel

Northern Israel was struck during July 2018 by a M L 4.4 earthquake followed by a seismic sequence that lasted about 30 days. This seismic sequence occurred in the center of a temporary seismic network deployed around the Sea of Galilee (Lake Kinneret). The network was installed to investigate the regional kinematics of the Dead Sea Fault, which is a major transform fault running N-S for more than 1,000 km. The data allowed us to develop a local velocity model for the Sea of Galilee. We relocated more than 600 earthquakes and calculated 27 focal mechanisms pointing out a complex kinematic setting, possibly controlled by fluids at depth. The seismic sequence developed along a NNW-striking direction and it is bounded to the east by the N-striking Dead Sea fault. Hypocenter depths range between 6 and 13 km. Directions of the principal stress tensors suggest a transtentional deformation, in agreement with the overall kinematics of the region. We analyze and discuss our data set to investigate mechanisms that potentially triggered the observed seismic swarm, including exacerbated ground water pumping proposed by previous authors. We suggest that the seismic sequence is driven by the dissipation of the elastic load that accumulated in this region.

“…The south‐western part of the Sea of Galilee was surveyed in the summer of 2003, when the lake level was 210.7 m bmsl (Reshef et al ., ) (Figs a and b). Detailed mapping of the bottom morphology and bathymetry was obtained with Marimatech E‐Sea Scan 800 sidescan sonar (325 kHz) and ODOM Echotrack dual frequency (24 kHz and 200 kHz) echo sounder.…”

“…Reshef et al . () have reconstructed the ancient outlet of the Jordan River to the Sea of Galilee (through the channel of the present Yavniel creek) north of Bet Yerah. This reconstruction is based on a Chirp survey and sediment analyses that show that the old alluvial fan of Yavniel Creek occupies the south‐western part of the lake.…”

“…Hurwitz et al (2002) and Reznikov et al (2004) mapped NW-SE segments southwest of the earthquake belt (Figures 2c and 2d). It is possible that due to acoustic disruption of seismic images in gas-rich sediments, the faults were missed (Ben-Gai, 2011;Lazar et al, 2019;Reshef et al, 2007). Gasperini et al (2020), and Wetzler et al (2019 suggested that the clusters are swarms.…”

Seismicity Induced at the Northern Dead Sea Transform Fault, Kinneret (Sea of Galilee) Basin, by Shallow Creep Involving a Salt Body

et al. 2022

The Dead Sea Transform Fault (Figure 1), a sinistral plate boundary (e.g., Freund et al., 1970), is longer than 1000 km and links spreading in the Red Sea with the Anatolian Fault System (Garfunkel, 1981;Sengör, 1979). The N-S-oriented fault has accumulated approximately 100 km of slip since the Neogene (Bartov et al., 1980;Garfunkel, 1981). Freund et al. (1970) and Garfunkel (1981) have suggested that an initial phase of 60 km slip involved pure transform motion, before a divergence component appeared. The southern sector of the transform is dominantly divergent with morpho-tectonic pull-apart basins (Figure 1): Gulf of Aqaba, Dead Sea, Beit Shean-Kinarot Basin, Hula Basin, and Marj 'Ayun (e.g., Ben-Avraham, 1985). Lake Kinneret (Sea of Galilee) fills the northern reaches of the Beit Shean-Kinarot Basin (Figure 2a).
