Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s): Marine Geohazards Sources and Probability (LQ00ENR)

Principal Investigator(s): Uri Ten Brink

Affiliate Investigator(s): Zvi Ben-Avraham (U. of Haifa); Eldad Levy (Geophysical Institute of Israel). Gideon Tibor (Israel Oceanographic and Limnological Institute); Steven Harder (U. Texas, El Paso). Organizations involved The Dr. Moses Strauss Department of Marine Geosciences, University of Haifa; Geophysical Institute of Israel; USGS

Information Specialist(s): Claudia Flores

Data Type(s): Seismics: Sonobuoy

Scientific Purpose/Goals: 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.

Vehicle(s):

Start Port/Location: Tel Aviv, Israel

End Port/Location: Tel Aviv, Israel

Start Date: 2018-03-20

End Date: 2018-04-11

Equipment Used: Seismic refraction

Information to be Derived: Velocity-depth model of the Dead Sea Fault and Galilee, northern Israel

Summary of Activity and Data Gathered: 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.
