plot_strike() plots strike angle as determined by
phase tensor azimuth (Weaver et al.2003 [1] ; Caldwell et al. 2004 [2])
and invariants of the impedance tensor. In the following example, we called
a sample of EDI collected in Huayuan locality, Hunan province, China,
stored as inner datasets. Moreover, plot_strike()
uses either MTpy or pyCSAMT as dependency. Use pip for
installation if is not installed yet:
We start by importing the required modules as:
import os
from watex.datasets import fetch_data
from watex.utils.plotutils import plot_strike
from watex.datasets.io import get_data # get edidata stored in cache
Before we’ll make a collection of EDI data and call
watex.utils.plot_strike() for plotting as:
fetch_data ( 'huayuan', samples = 25 ) # store 25 edis in cache
edi_fn_lst = [os.path.join(get_data(),f) for f in os.listdir(get_data())
if f.endswith('.edi')]
plot_strike(edi_fn_lst )
by default, plot_strike() plots all period ranges into
one polar diagram for each strike angle estimation with kind=2. To plot
individual decades into one plot, set the kind parameter to 1 as:
plot_strike(edi_fn_lst , kind = 1 )
Total running time of the script: (0 minutes 6.634 seconds)
