Shallow seismic reflection investigations of the Big Creek
and its extension into the Memphis, Tennessee area:
Collaborative with Millsaps College, Jackson, MS.
The Big Creek Fault Zone is a poorly known fault included in the southern portion
of the New Madrid Seismic Zone. It's poorly known trend is projected from Arkansas
in a northeasterly direction across Mississippi toward Memphis, Tennessee. The
project goal is to better understand this fault zone and produce data to help
evaluate its potential to produce earthquakes. This project is a collaborative
effort with the Department of Geology at Millsaps College, which will obtain
land-based seismic profiles along the fault trend in Arkansas and Mississippi,
while the MMRI will obtain water-based profiles in the Mississippi River and
the Wolf River in Tennessee. The river seismic profiles will seek to identify
the location in the Mississippi River where the Big Creek Fault crosses from
Arkansas into Mississippi and to determine if there is identifiable faulting
in the Wolf River along the projected trend of the Big Creek Fault. Click here
to view the seismic profile
acquired in the Wolf River, in Memphis, Tennessee. It is also hopeful that
the river seismic profiles will elucidate faulting style and magnitude. The
Seistech high resolution seismic profiling system was the primary system used
to obtain the water-based seismic profiles.
