Detailed explanation-1: -The three main reasons are wastewater injection, hydraulic fracturing and enhanced oil recovery. Within the United States, each of these three activities has induced earthquakes to varying degrees in the past few years.

Detailed explanation-2: -The primary after effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, liquefaction, destruction of livelihood, death and injuries. Rainfall is not an after-effect of earthquake.

Detailed explanation-3: -“Induced” earthquakes are those where external anthropogenic activities cause stress and failure within a rock not close to natural failure. Earthquakes produced by hydraulic stimulation, including both fracking and the creation of Enhanced Geothermal Systems (EGS) can be either triggered or induced.
