To understand seismogenesis in shallow
parts of subduction zones, it is vital
to know about strength and frictional
parameters of subducted sediment.
For this purpose, PETROTEC,
as part of the TIPTEQ-Project, gathers
geotechnical data for sediments deposited
on the incoming Nazca Plate,
the trench and the slope off the southern
Chilean coast during the last 5 Ma, and
whose equivalents are now being underthrusted
into the seismogenic zone beneath
South America.
Material comes from gravity cores collected
during R/V SONNE Cruises
SO181 (Flüh E. & Grevemeyer I (Editors)
2005), SO102 (Hebbeln D, Wefer
G, et al. 1995) and SO156 (Hebbeln D,
et al. 2001), as well as from ODP Leg
141 (Behrmann JH, et al. 1992) drill
cores.
Sediment strength and frictional properties
are determined by triaxial testing,
ring shear testing and direct shear testing...
