Visualising faults as focal mechanisms

Part of "The Shear Zone" video channel. This uses four examples to illustrate how to plot tectonic fault kinematics on a stereonet in a way comparable to earthquake focal mechanisms (beach balls).

Always brief, concise, and comprehensive as well! Thank you prof. Butler

Dear Rob Butler, thank you for the video, it clarified many things for me regarding the topic. Greetings from Bolivia.

Glad it helped!

Thank you. Easy to understand.

thanks - glad it was useful

Thanks.

Wholly heck diagraming the numbering system on that graph makes so much more sense than the other videos Ive watched trying to suss out how what strike, dip, and rake represent! Which as a Californian it worries me this kind of geology is not a bigger part of our curriculum. Also, much like how to mathematicians a sphere with a hole in it is called a torus and to physicist its a doughnut, I find it hilarious we Americans call a stereogram a 'beach ball'.....I mean, it makes sense, it does look like a beach ball, just [🙄sigh😏] stay classy, America.... Anywho, awesome explanation, mate! You taught me something new today, on a level I actually understand how it works! I wish I had teachers that explained things as clearly as you have [virtual internet high fives].

This is amazing! Thank you!

When you “look down,” do you orient yourself north or along the fault plane

[@robbutler2095]

for kinematics, view the fault - but for regional tectonic significance, the geographic context (N) would be important.
