Jun 21 32 This week’s 53 magnitude earthquake that struck near Moe in Victoria’s brown coal mining region of the La Trobe Valley brings to mind the 56 magnitude quake of in another coal mining Routine United States Mining Seismicity For these reasons it is likely that a small percentage of events that we have labeled as routine mining seismic events are in fact natural earthquakes that are unrelated to mining activities and another small percentage are probably unplanned rockbursts

Apr 24 32 Seismic monitoring is extremely important in any situation where human activity may change the stress regime in the crust of the earth be it through nuclear explosion testing geothermal energy production storing carbon emissions underground or extracting minerals or gases from the earthPennsylvania may not be famous for its earthquakes like some other states but seismic events happen every week at quarries and other mining areas as does the occasional earthquake When a seismic event occurs in the commonwealth the Pennsylvania State Seismic Network is the first to know

Jul 12 32 Background Human induced earthquakes have become an important topic of political and scientific discussion owing to the concern that these events may be responsible for widespread damage and an overall increase in seismicity It has long been known that impoundment of reservoirs surface and underground mining withdrawal of fluids and gas from the subsurface and injection of To analyze the problem USGS began setting up temporary seismic monitoring stations across the region This allows the department’s scientists to pinpoint more accurately seismic locations to determine if there is a relationship between mining fracking and wastewater injections and human induced earthquak

Earthquake Earthquake Volcanism A separate type of earthquake is associated with volcanic activity and is called a volcanic earthquake Yet it is likely that even in such cases the disturbance is the result of a sudden slip of rock masses adjacent to the volcano and the consequent release of elastic strain energy The stored energy however may in part be of hydrodynamic origin due to Jul 13 32 In terms of safeguards against earthquakes there’s very little In my experience in many countries in the mining industry the effects of earthquakes have been largely ignored Obviously tailings dams should be designed to take into account the horizontal accelerations associated with seismic activity and I think that’s generally the case
