2011 Oklahoma quake - man made? 2011 Oklahoma quake - man made? JAE (Structural) (OP) 27 Mar 13 09:02 Can humans cause earthquakes? According to this article, some think so (the Oklahoma 2011 5.6 mag. quake) Article on 20111 OK event RE: 2011 Oklahoma quake - man made? PicoStruc (Structural) 27 Mar 13 14:11 Similar theory exist about dam water level that can cause earthquake http://www.wired.com/wiredscience/2008/06/top-5-wa... And more seriously : Dam Induced Earthquale http://www.internationalrivers.org/files/attached-... RE: 2011 Oklahoma quake - man made? msquared48 (Structural) 27 Mar 13 14:31 And then there's HAARP.... I tend to believe the possibility of the water induced quakes due to the factor of induced lubrication, allowing any excisting faults to slip at a lower level, should they need to. Just makes sense to me. Mike McCann MMC Engineering RE: 2011 Oklahoma quake - man made? asixth (Structural) 30 Mar 13 20:29 There was a similar theory about the 1989 Newcastle quake (Magnitude 5.5) in Australia about mining activities de-stabilizing the plate. I didn't read too much into it but it was a significant event in Australia for engineers, really made engineers consider earthquake design. Prior to that it was thought of a "need not be considered" thing. RE: 2011 Oklahoma quake - man made? DSB123 (Mechanical) 26 Apr 13 07:20 asixth, You had me slightly worried there for a moment. I read 1989 Newcastle quake (magnitude 5.5). As I live about 15 miles from Newcastle (UK) I could not remember any such earthquake. Then I read on and "in Australia" eased my concern somewhat. That's the benefit of living in a Country that does not have significant Seismic activity.
