The main objective of the research was to obtain an image of the Dead Sea fault sub-surface geometry and a map of the sub-surface seismic velocities along the axis of the basin to a depth of 15-20 km at a resolution of ≥1 km.
Location
Galilee, Sea of Galilee, Israel, Middle East, Northern Israel, Jordan River Valley
Summary
Two perpendicular wide angle seismic refraction / reflection cross-sections were acquired in order to image the Dead Sea fault structure in the northern part of Israel; A west-east line, from the Mediterranean coast line near Acre in the west to the Syrian border in the Golan Heights in the East with total length of 72 km; A south-north line, from Kibbutz Kfar Rupin in the south to Almagor settlement in the north crossing the Sea of Galilee with total length of 50 km. The seismic energy sources were 12 underground explosive shots, 300–400 kilograms each located every ~10 km, while the 550 seismic receivers were located every ~200m along the lines. Local earthquakes and mining explosions were also recorded.
Info derived
