I was not given the summons, but found it on my doorstep after returning from a long weekend away (I live alone, so no one was home when it was delivered). First, I want to know if it was properly served, and if so,...
Fracking itself can also induce earthquakes, but the technique has never caused earthquakes greater than magnitude 4. For comparison, an Oklahoma injection well is thought to have triggered a magnitude-5.6 earthquake in 2011. Mining blasts and geothermal energy plants can also trigger earthquakes. Quake road map.
We have talked above seismic waves and how they vibrate the ground which can lead directly to the collapse of structures. There are other, secondary effects that are caused by earthquakes, most often a result of strong shaking. A simple example common in many earthquakes are landslides. The shaking causes regions of the rock and soil to slide downhill. The same material would eventually fail with increased time, but earthquakes trigger many slides that do much bit of damage.
