Haiti's Earthquake: Natural or Engineered - by Stephen Lendman
Human activity can cause destructive harm. Columbia University geophysical hazards research scientist, Christian Klose, studies how, including from mining. In a recent paper, he said:
"mining activities disturb the in-situ stress in the upper continental crust and can trigger earthquakes (human-triggered seismicity)."
Past examples are numerous:
-- from potash and other mining in Germany since the 19th century;
-- potash mining in Bulgaria;
-- copper mining in Silesia;
-- ore mining in Russia;
