Average Motion

“Cuadrilla said it appreciated the tremor [of 2.9 magnitude] had ’caused concern for local people’ and said ‘it is worth noting that this event lasted for around a second and the average ground motion recorded was 5mm per second. … This is about a third of that permitted for construction projects.'” https://www.bbc.co.uk/news/uk-england-lancashire-49471321

However, there is a much higher requirement for destruction projects.

Metaphord

As nearly 200 governments meet in the Peruvian capital, Lima, to thrash out a draft deal to cut carbon emissions in a bid to ward off more global warming, high in the Peruvian Andes, a region prone to earthquakes, “scientists warn that if a giant chunk of ice from the Hualcan glacier breaks off it could trigger a tsunami-like wave.” (http://uk.reuters.com/article/2014/12/11/us-climatechange-lima-glaciers-idUKKBN0JP21920141211)

“The surge in seismic activity [in Oklahoma] has left residents and experts alike wondering about the underlying cause.” (http://www.nature.com/news/wastewater-pumping-ups-oklahoma-s-seismic-activity-1.15512)

Underlying, it turns out, are millions of barrels of wastewater from fracking.

Quake

A government representative “dismissed concerns over water pollution from fracking in the UK, and the very small earthquakes caused … ‘It will not contaminate water supplies. It will not cause dangerous earthquakes.'” (http://www.theguardian.com/environment/2013/sep/09/fracking-shale-gas-ed-davey-climate-change)

Just non-dangerous ones.
