Matlab codes are generated to compute the fault parameters of nodal plane 2 or the auxiliary plane.
Normally, the DMT inversion creates two nodal planes. Only one nodal plane agrees with fault lines in a topographic map (Figure 2), which is specified and presented in Table 2 as the values of strike, dip, and rake.
They were characterized by a shear mechanism and the nodal plane trend was in NE-SW direction (such as the fault VIa).
The plane of the nodal plane agrees well with the structure by the locations of AE.
The shallow, normal mechanism was determined by the ETHZ Swiss Moment Tensor Solution for the main earthquake on November 30, 2004: h = 4km, [M.sub.o] = 6.3E+22dyn cm, [M.sup.W] = 4.5, Nodal Plane 1: strike = 246, rake = -80, dip = 66, Nodal Plane 2: strike = 43, rake = -112, dip = 26, (http ://www.seismo.
With respect to SUW, as will be discussed later, SUW happened to be located close to the nodal plane of P waves and in the direction of maximum Sg waves (compare seismograms in Figure 4).
Each mechanism consists of steep or moderately dipping WNW-ESE to NW-SE trending nodal plane and of another steep NNE-SSW to NE-SW trending nodal plane.
The strike and dip of the first nodal plane are 355[degrees] and 57[degrees] respectively.
The main idea is then to determine if matching the nodal planes of both elements in the annular array may enhance the synergy of both elements and have some positive influence on achieving a more uniform displacement of both elements and a more reduced cross-talk.
