Implication

Observational analysis identifies hidden faults linked to micro-seismic activity in the Maros-Pangkep region, suggesting significant environmental risks.

Key Points

  • The analysis revealed clustered hypocenters indicating potential hidden faults, with a striking geometry of 333° to 346° and low-stress regime in the region.
  • 191 earthquake events were relocated, producing a b-value of 1.34, suggesting a significant presence of small-magnitude seismicity linked to the area's geology.
  • Data-driven techniques using the double-difference method were employed to analyze micro-seismicity and characterize the local tectonic settings effectively.
  • The results highlight the necessity for integrating seismicity data in assessing hazards and managing karst environments that face risks like land degradation.
