Cross section with respect to a earthquake lcoation and strike

[aqeel-magsi]

Hi, I am new to GMT and using version GMT6.
How can we plot a cross-section line of 200km with respect to strike and given latitude and longitude?

I suggested to plot use GMT project but there is no option of the strike.

Thank you

How extend profile?

I have a profile (see below) that lengths ca. 15 km. and I want extend the profile that same distance in both direction. I.e. I want to add two extra points (at the beginning and the end following its azimuth) at a distance of 15 km (so the new profile would be 45 km). I think it should be easy but I can’t figure out how to do it. # Long Lat -66.04971205 -55.14285297 -66.01518493 -55.11524701 -65.97886793 -55.08903702 -65.94340697 -55.06219498 -65.90790703 -55.03662696
