Coal Mining Causing Earthquakes, Study Says
`The most damaging earthquake in Australia’s history was caused by humans, new research says.
The magnitude-5.6 quake that struck Newcastle, in New South Wales, on December 28, 1989, killed 13 people, injured 160, and caused 3.5 billion U.S. dollars worth of damage [..]
That quake was triggered by changes in tectonic forces caused by 200 years of underground coal mining, according to a study by Christian D. Klose of Columbia University’s Lamont-Doherty Earth Observatory in Palisades, New York.’
