Hi everyone,
I am trying to plot FMS as per the instruction provided on pygmt web page. However, i did not get any result. Error message saying that my file is not in correct format. May someone suggest me how i can prepare a file including the label text for each FMS beach ball.
data=pd.read_csv("FMS.txt", sep='\s+')
fig.meca(spec=data, convention='aki', offset=True, scale='0.3c', C=True)
FMS.txt (280 Bytes)
Hello @Adnan,
You have to use longitude and latitude for the columns names, instead of lon and lat.
Futhermore it looks like you mixed up longitude and latitude for either the event location (colums longitude and latitude) or the plot location (colums plot_latitude and plot_longitude) in your FMS.txt file:
longitude latitude depth strike dip rake magnitude plot_latitude plot_longitude
73.47 34.38 12.0 334 40 123 7.6 73.67 34.42
71.27 32.95 15.0 237 5 79 6 71.40 33.05
73.85 32.83 14.7 246 10 52 5.9 73.95 33.00
73.21 33.92 22.1 148 82 6 5 73.31 34.00
73.51 32.62 24.7 246 21 61 4.9 73.39 32.50
To add labels to the single beachballs you need a column event_name containing the desired text:
longitude latitude depth strike dip rake magnitude plot_latitude plot_longitude event_name
73.47 34.38 12.0 334 40 123 7.6 73.67 34.42 event_1
71.27 32.95 15.0 237 5 79 6 71.40 33.05 event_2
73.85 32.83 14.7 246 10 52 5.9 73.95 33.00 event_3
73.21 33.92 22.1 148 82 6 5 73.31 34.00 event_4
73.51 32.62 24.7 246 21 61 4.9 73.39 32.50 event_5
Thanks for suggestions,
It works well but only without the event label.
For example, if i use the following format, it plots the FMS
longitude latitude depth strike dip rake magnitude plot_longitude plot_latitude
73.47 34.38 12 334 40 123 6.4 73.85 34.75
But when I add the event label, then error.
longitude latitude depth strike dip rake magnitude plot_longitude plot_latitude event_name
73.47 34.38 12 334 40 123 6.3 73.85 34.75 m6-2010
Plus, I also like to include direction from epicenter toward the source.
Try separating your values with a tab, not a space.
Good luck!
