More induced seismicity resources.

I hope you are enjoying the summer. Things are especially busy this summer for reasons unknown.

For those who might be living in a cave somewhere, the investigation of background variation in earthquake frequency related to produced water injection has become a very hot topic.   Some earlier posts covered this, but here is another one.

An excellent USGS reports about the subject, focused on Oklahoma, can be found here.

An easily understood overview regarding these events can be found here.

A USGS OpenFile report: Incorporating induced seismicity in the 2014 US National Seismic Hazard Model–Results of the 2014 workshop and sensitivity studies. Can be found here.

A series of presentations and other documents from an excellent induced seismicity workshop, coincident with a major winter weather event in Oklahoma (!), can be found here. 

An important Science article, by William Ellsworth, can be found here. Be sure to carefully review this and his excellent and accessible presentations that can easily be found on the web.

A Virginia Tech resource related to induced earthquakes can be found here.

The Kansas Geological Survey (an excellent organization), has induced seismicity related information that can be found here.

As earlier posted, but very useful and helpful, the Lawrence Berkeley National Laboratory site discussing induced seismicity can be found here.

The induced seismicity wiki can be found here.

To prove that people are following this activity, take some time and read this popular press article about “Underground Weather”.

Predicting earthquakes–that should be easy eh?  IMO, if the appropriate tensor nature of the earth system,  multi-scale physics, heterogeneity, and anisotropy  are properly incorporated it should be a piece of cake.

  1. If I remember correctly, the potential for man to directly affect the seismic activity of a region, was first recognized due to an uptick in seismic activities when building and filling dams. I know some people freak out over the notion that fracking can induce earthquakes.

    But is it a bad thing?

    Are we not releasing tension before it can build to produce an even bigger quake? Or are we just shifting tensing that will be a bigger quake anyway when released?
