Overview

  • Search teams completed the recovery on Monday, confirming that all five trapped miners died in the collapse
  • Authorities have launched criminal proceedings and safety evaluations to determine whether a natural quake or mining practices triggered the tunnel’s failure
  • Codelco has suspended operations at El Teniente and evacuated 3,000 workers pending regulatory clearance
  • President Gabriel Boric declared three days of national mourning to honor the fallen miners
  • The tragedy highlights the risks of mining in Chile’s seismic Andes region, where natural tremors and extraction activity intersect
