Comment induced quakes have been around for decades (Score 1) 166

The most famous induced earthquakes was Rocky Flats outside of Denver in 1965. It was a waste injection well like these fracking-waste wells. Colorado also has had M5 quakes from agricultural salt water injection in the west near Rangley and coal methane waste injection south near Trinidad.

Quakes may be associated witht loading or drainign of large water dams. The 2008 Sichuan China quake could have been one of these.

Geothermal energy projects sometimes have induced quakes. Most geothermal project inject water for heating.

Comment precedence of merging faluls in China & Japan (Score 1) 63

The 2011 quake that clobbered the nuclear reactors in Japan was three historic faults going off at once and one of the largest quakes in recorded history- a rare M9 quake. Although there was a Tsunami seawall and nuclear shutdown systems, they had not designed for this large an earthquake.

Ditto the 2008 China Sichuan quake- it broke several nearby faults, resulting in a unexepctedly large quake. Neither China nor Japan had seen quakes this large in these areas in over a thousand years of recorded history.

So USGS seismologists are rightly concerned whether this could happen in the US.
