- •
Focal mechanisms and Mw of 11 small events calculated at temporary local stations.
- •
Local stress field is typical for reverse faulting with minor strike-slip component.
- •
The optimally oriented fault (strike 254°) does not correspond to the Transbrazilian Lineament.
- •
Feasibility of waveform inversion of Mw 1–2 events at near stations <5–10 km and <2 Hz.
