The verdict

What if a great earthquake hits Chile's copper belt?

For this scenario, about 6.3% of the world's copper exports would be exposed to the disruption, and the 60-day assumed stockpile cover outlasts the 30-day disruption.

No close historical match in our records — this scenario is outside our recorded experience.

Guided scenario

What if a great earthquake hits Chile's copper belt?

Chile and Peru mine about a third of the world's copper. Past quakes stopped mines for hours or days — but structural damage has no modern analog. Model the harder case explicitly.

1The setup

Chile produces roughly a quarter of the world's mined copper — about a third together with Peru — and 18.0% of world copper exports ship from Chile (2024 vintage). The subduction zone off its coast has delivered three measured shocks: the 2010 Maule quake (M8.8) shut mines holding ~20% of Chile's output and COMEX copper jumped 9.25¢/lb before mines restarted within days; the 2007 Tocopilla quake (M7.7) spiked copper 6.29% intraday; 2015's Illapel (M8.3) added 1.1%. The pattern is consistent: even great quakes interrupted output for hours to days, and the price spikes faded. A quake that damages a concentrator or a tailings dam would be outside the modern analog set — the top magnitude band models that case on purpose. The dial covers Chile's exports; Peru's mines sit in the same seismic belt but outside the monitor's exporter data.

Closest live contract — whether a 6.0+ quake hits Chile within the calendar month, on a monthly clock. It is not a forecast of a great (M8+) earthquake, and it is not a contract on copper prices. Thin market — few traders; small bets move these odds.

Resolution: Assumed days of stockpile cover — an assumption, not a measured buffer

What this assumes
  • Exposure: Target share 18.0% × severity 35% = 6.3% exposed.
  • Uncovered days: max(0, 30 − 60) = 0.
  • Exposed ≠ lost: affected trade can reroute, draw down stocks, or find substitutes — this number sizes the exposure, not the damage.
  • Exporter share ≠ spare capacity: rivals may not be able to surge supply to fill the gap.
  • Stockpile cover of 60 days is your assumption, not a measured buffer.
  • Results are physical-exposure arithmetic from your stated assumptions — not a price forecast.

How the shock travels

Mine output

Quakes stop mines through power outages and safety inspections: the 2010 M8.8 shut mines holding ~20% of Chile's output, and 2015's M8.3 idled ~2.2 Mt of capacity — all restarted within days.

Evidence: USGS event pages + Cochilco monthly output (2010, 2015) — mines restarted within days of M8.8 and M8.3 shocks

LME copper price

Even great quakes moved copper briefly: COMEX jumped 9.25¢/lb in 2010, 6.29% intraday in 2007, 1.1% in 2015 — each faded as mines restarted.

Evidence: Exchange price history — Tocopilla 2007 +6.29% intraday, Maule 2010 +9.25¢/lb, Illapel 2015 +1.1%

Concentrate and cathode shipping

Port closures and road damage can delay concentrate shipments for days; Chile's coastal mines ship through quake-exposed ports.

Evidence: 2010 reporting — outages, not building damage, stopped the mines; ports reopened with the grid

Caveat: No measured modern analog for port-outage duration at Chilean copper ports — this channel is the least evidenced

No single corridor — share not applicable — Chilean copper loads at Antofagasta / Mejillones Pacific ports; no single chokepoint. No route share applies -- this is not missing research.

How we map this

Exporter and importer shares are 2024 vintage · annual data, 1–2y lag from UN Comtrade and OEC (BACI/CEPII); an importer counts as exposed when ≥20% of its copper imports come from a shocked exporter. The shock geography is the scenario’s own focus selection. Annual data with a 1–2 year reporting lag — the structure moves slowly, the prices don’t.

For perspective, not prediction

No structured comparable records for this scenario yet. Where the setup above narrates historical episodes, those are drawn from contemporary reporting — they have not yet been structured into comparable records.

What to watch

  • USGS magnitude and location — the 2010 Maule quake was M8.8, Tocopilla 2007 M7.7
  • Which mines report shutdowns: Escondida, Collahuasi, El Teniente, and Andina sit in the seismic zone
  • Chilean port status and grid blackouts — in 2010 the power outage, not building damage, stopped the mines
  • LME 3-month copper: the grading line is a sustained ≥10% rise over 30 days, not the intraday spike
  • Cochilco's monthly Chilean mine output — the physical confirmation
