Based on damage and ...

Earthquakes are caused by the slow deformation of the outer, brittle portions of "tectonic plates", the earth's outermost layer of crust and upper mantle. Due to the heating and cooling of the rock below these plates, the resulting convection causes the adjacently overlying plates to move, and, under great stress, deform.Six Facts on Induced Earthquakes. Fact 1: In the United States, fracking is not causing most of the induced earthquakes. Wastewater disposal is the primary cause of the recent increase in earthquakes in the central United States.

Earthquakes can be measured using a device called a seismometer and a device that also records is known as a seismograph. They use an instrument to measure the magnitude of the earthquake, called a Richter scale. The big earthquakes not only occur on land but also in the sea. Such earthquakes give rise to giant waves called tsunami, …Determining the proportion of anthropogenic to naturally stored energy is very difficult, although in the case of larger earthquakes it is clear much of the energy is of natural tectonic origin. We use the term “induced” for both cases, which is in keeping with the convention of the Committee on Induced Seismicity Potential (Hitzman, 2013).Science agencies and regulators finally seem to be taking induced earthquakes seriously. For a long time, the Oklahoma Geological Survey was reluctant to link the earthquakes to oil and gas operations. But in a statement released on 21 April, the agency now says that it is "very unlikely" that the surge in earthquakes represents a …In Netherlands, there have been over 1000 induced earthquakes in the Groningen gas field since 1986.
