Man-Made Earthquake
Did you know that there are such things as man-made earthquakes? Well, it’s been happening since the 19th century and human activity is what causes the problem. In fact, it has been one of the sources of more than 200 earthquakes, and other culprits are extraction of gas, oil, or water; fluid injection; and the creation of reservoirs. It is calculated that the losses caused by a quake that happened in Australia exceeded the total amount of money earned from mining since operations began in that area two centuries ago.
