| Abstract |
An integrated multi-institutional effort of multi-scale seismic
imaging of the Mariana Subduction Factory (MSF). The PIs will conduct
multi-channel seismic reflection profiling, controlled-source wide-angle
reflection/refraction profiling and passive recording of local and
teleseismic earthquakes through OBS deployment to be carried out
with Japanese investigators. The data will provide a comprehensive
velocity and attenuation, structural and stratigraphic image of
the MSF. The principal objectives of the study are to understand:
1) velocity and attenuation structure of the mantle, 2) large-scale
flow of the mantle wedge, 3) velocity structure of the subducting
oceanic crust, 4) seismic stratigraphy and structure of the forearc,
arc and remnant arc, 5) the magma chamber below the volcanoes, 6)
a possible double seismic zone, and 7) updip an downdip limits of
the seismogenic zone. The study will also help in the planning and
eventual drilling in the Mariana island arc system. |
