GEOLOGY

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 Denver Earthquakes of the 1960s are a few of many examples of humans causing earthquakes. In fact, over the years, earthquakes have been attributed to human activities ranging from nuclear bomb detonation and dam impoundment to oil and gas extraction and underground mining.

Detailed explanation-3: -Earthquakes can be induced by a wide range of causes including impoundment of reservoirs, surface and underground mining, withdrawal of fluids and gas from the subsurface, and injection of fluids into underground formations.

Detailed explanation-4: -Induced seismicity is typically earthquakes and tremors that are caused by human activity that alters the stresses and strains on Earth’s crust. Most induced seismicity is of a low magnitude.

Detailed explanation-5: -While most earthquakes are caused by the slipping of tectonic plates, minor earthquakes can also be caused by volcanic eruptions, collapse of rock formations on Earth’s surface, or underground explosions.
