According to Appendix A-4 of the NSR-10, of the 25 municipalities of Sucre, all are in the intermediate seismic hazard zone. The capital, Sincelejo, has Aa = 0.10 and Av = 0.15, intermediate hazard. Across the department, Aa ranges from 0.10 to 0.15 and Av from 0.15 to 0.15.

What does it mean for design in Sucre?

Municipalities in the intermediate hazard zone. In reinforced concrete, the intermediate hazard zone no longer allows minimum dissipation (DMI): the structure is designed with moderate (DMO) or special (DES) energy dissipation capacity, with more reinforcement detailing requirements.

The municipality's value is only the starting point: the soil profile sets the coefficients Fa and Fv, and the occupancy group sets the importance factor. Work out the full spectrum with the NSR-10 design spectrum, or look up another municipality in the seismic hazard tool.

What the code requires in Sincelejo, with each city's soil and environment, is on its structural engineering page.
