Talk:Induced seismicity

message: Don't know a lot about this subject, but I think it's important enough to have an article, and have cobbled together a bit of info from the web about it. If anyone can provide specific examples where induced seismicity has occurred, that would improve the article greatly! --Lancevortex 13:17, 25 Sep 2004 (UTC)

replies: text: yes - the following pdf (Geothermal Reinjection at the Hengill Triple Junction, SW Iceland) confirms that - I'll be adding it as a reference for the CarbFix article. EdwardLane (talk) 11:09, 27 September 2011 (UTC)

message: It needs to be added that the research that produced the figures for this table is inconclusive (certainly after reading the abstract of the Cerro Prieto one). In fact, should this table be included at all?  It seems to set-in-stone something that isn't certain.  Thanks,  TheJoff (talk) 13:47, 14 November 2011 (UTC)

message: Hi,
Could we also add the Mohr-Coulomb failure criterion for faults? Most seismicity seem to be connected to this criterion due to effective stress going down as a result of the increase in pore pressure.

thread_title:  Mohr-Coulomb Criterion 

message: Nearly all the dates listed in the subsection on earthquakes and wells are recent - 2009 and newer, this may mislead readers into thinking this is a newly discovered phenomonom.  The link between injection wells and earthquakes has been known about for decades.  The examples are also local to Oklahoma, which is not the only location such quakes have been seen to occur.  That leads me to think the section is of fairly subjective content and could benefit from being changed to a more objective stance (read as: one state does not a world create, nor do a single individuals experiences cover the entire breadth of human knowlegdge - put some proper research into the subject because what's there now will lead people to wrong conclusions). 174.29.85.161 (talk) 08:37, 27 September 2016 (UTC)
thread_title:  Injection well quakes - old news 

message: Hello, we are a project group for UC Berkeley working on a Wikipedia editing  project and we would like to add a section to this article about induced seismicity due to carbon capture and storage.
We would like to add two sentences to the end of the lead section as follows:
Induced seismicity can also be caused by the injection of carbon dioxide as the storage step of carbon capture and storage, which aims to sequester carbon dioxide captured from fossil fuel production or other sources in earth’s crust as a means of climate change mitigation. This effect has been observed in Oklahoma and Saskatchewan [9]. Though safe practices and existing technologies can be utilized to reduce the risk of induced seismicity due to injection of carbon dioxide, the risk is still significant if the storage is large in scale. The consequences of the induced seismicity could disrupt preexisting faults in the Earth’s crust as well as compromise the seal integrity of the storage locations [10].

Other proposed changes to this article we would like to make are: 
Other plans and other sources:
Create a section for induced seismicity due to CCS
Make a comparison of risks associated with natural gas storage/hydraulic fracturing/ wastewater injection and CO2 sequestration (use examples of Castor gas project in Spain or induced seismicity in Oklahoma due to wastewater injections)
Describe the importance of understanding induced seismicity due to storing CO2 because the volumes of fluids injected in the case of CCS largely exceed volumes associated with waste water injection (see Figure 1 Verdon, J.P. (2014), Significance for secure CO2 storage of earthquakes induced by fluid injection, 2014, Environmental Research Letters, Vol. 9, doi:10.1088/1748-9326/9/6/064022.)
Describe Mohr-Coulomb failure criteria and explain how underground injection can lead to an increase in normal stress, shear stress or pore fluid pressure changes leading to failure on an existing fault plane.
