Qademah Fault
Passive Data
28 Sept. 2014 -
3 Oct. 2014
OBJECTIVE:
In this field
trip we collect passive data to
1.
Convert passive to surface waves
2.
Locate Qademah fault using surface wave
migration
INTRODUCTION:
In this field
trip we collected passive data for several days (see table 1). This data will
be used to find the surface waves using interferometry and then compared to
active-source seismic data collected at the same location (Figure 1).
A total of 288 receivers are used. A 3D layout with 5 m inline intervals and 10
m cross line intervals is used (Figure 2), where we used 12 lines with 24
receivers at each line. Receiver order is shown in Figure 2.
