Paleoseismic and neotectonic studies are being conducted in collaboration with Mustapha Meghraoui (IPG Strasbourg) as well as Syrian and Lebanese colleagues. Some examples are shown here.
Our first paleoseismic trench was opened along the Serghaya Fault zone
during the Spring of 2000 and revealed evidence of at least 5 large Holocene
earthquakes along this fault which has generally been regarded as inactive.
The photo above (facing south) shows the trench system parallel to and
crossing the 4 meter fault scarp. A mosaic of one of the trench walls
(left) depicts several.shear zones (click on photo for enlargement).
Spring of 2001, we excavated several trenches along the main Dead Sea fault
system (locally known as the Ghab fault) near the town of Misyaf (about
50 km north of the Lebanese-Syrian border). This area is particularly
interesting because a Byzantine aqueduct has been displaced by about 9
meters at the fault (see photo at right). Preliminary results suggest
that this part of the fault has not produced a large earthquake in the
last ~800 years. The precise timing of the 4 paleoseismic events
documented in the trenches is being refined with ongoing radiocarbon dating.
