It's taken me a while, but here is my first interferogram of the Venezuela earthquakes from Sentinel-1. It's an ascending track to the west of the epicenter, and the pattern of displacements is consistent with slip on a fault that runs close to and parallel to the coast.

Descending track data covering the epicenter and Caracas has been acquired... will be back with that later.

It’s been a minute since I’ve looked at interferograms… how much vertical displacement is represented by each cycle?

The symmetry of the pattern means it's almost certainly horizontal movement here. Each fringe is 2.8 cm of line-of-sight displacement, and assuming it's horizontal motion on an E-W fault represent about 4-5 cm of E-W displacement each.

This captures where the fault rupture ended (where the fringes pinch together, more or less). I would expect a lot more displacement in the data to the east.
