- •
We modeled the track rupture front and orientation of the most energetic events in Puerto Gaitan, Colombia during 2014.
- •
We applied the Moment Tensor Retrieval for estimating focal mechanisms.
- •
We applied a joint inversion focal mechanism to find the stress tensor in the area.
- •
Based on spatial and temporal distribution, we hypothesize that seismicity is induced by oil operations in the study area.
