  1. Expansion and Contraction on Europa C. Culha EPS 109 Final Presentation

  2. Lineament Europa: • Bands • Width: 4-30 Km • Form through expansion • Analogous to mid-ocean ridges • Double Ridges • Narrow • Very long and abundant on surface • We know very little about these features Culha, Hayes,Manga, Thomas Culha, Hayes,Manga, Thomas Culha 2/40 8/40

  3. Reveal tectonic motion Europa: Contracting and Left Lateral Expanding and Right Lateral Culha, Hayes,Manga, Thomas Culha, Hayes,Manga, Thomas Culha 2/40 8/40

  4. example Europa: • LIMITATIONS • Features crossing under younger feature • Identifying lineaments • Angle variations • RESULT • There is a relation between angle at which features intersect younger features and the amount of offset they experience • METHODS • Recreate initial surface • PDE • Geometry • Matrix Manipulations • Interactive • Run code: • ExpandContract • 1 means yes • 0 means no Culha, Hayes,Manga, Thomas Culha, Hayes,Manga, Thomas Culha 2/40 9/40
