I'm beginning to explore possible causes of earthquakes in or near my area. I am suspecting that the pain does not just come from larger scale activity all over the world. I have a feeling there could possibly be something going on closer to where I am. I have discovered that the pain comes from a feeling like something is about to pop. I have an idea of what makes it hurt before an earthquake. I know the difference between a natural earthquake and an artificial event such as an explosion. In the past, it is like a bubble is about to burst before an earthquake. Stress suddenly increases or a small amount spikes to a critical point, it gets really tight and hot and then it lets go. That is what it feels like. I am aware that there is a vast quarry in my area and I'm thinking that can lead to induced seismicity. There are also some fracking sites around TN. I'm trying to understand the mechanisms in earthquakes on this part of the country. I understood them quite well back over in California on a tectonic plate zone. An earthquake is very much a release of energy after a build up of stress deep in the ground. They typically occur in a fault or disturbance in the earth. When it comes to intraplate earthquakes, it does not involve tectonic plate movement. Some of the causes are pre-existing zones of weaknesses that can reactivate(e.g. New Madrid Seismic Zone). There are also suggestions of them being caused by mantle plumes. I have a feeling a number of earthquakes go undetected in this part of the country. I do feel a lot out here at times. It can be confusing and difficult where it feels like I'm being pulled in different directions.
