Human activity can cause, or at least trigger, earthquakes in an otherwise earthquake-prone region.
Underground mining, such as that done in coal mining, can trigger earthquakes. The very action of extracting coal and fluid can cause stress on the earth.
Instability due to excavation during construction of major engineering projects (e.g. dams) can also be a man-made trigger for earthquakes.
A 1961 study by scientists suggested that earthquakes could be caused by injecting fluid waste into the earth's crust under high pressure.
Extracting natural gas from the earth can trigger seismic activity. Drilling and fracking (which means using pressurised fluid to fracture rocks, thus releasing natural gas or coal seam gas) has links to earthquake activity.
fluid is used to fracture rock layers in the earth's crust in order to release petroleum (oil), natural gas, coal steam gas,

Can hurricanes and earthquakes happen underwater?
hurricanes no, earthquakes yes. thats what causes Tsunamis... underwater earthquakes.
What causes corrosion on manmade structures?
acid rain destroys man made structures
What are the manmade causes of tsunami?
collection of soil from rivers and lakes near to oceans on large scale causes landslides which are capable to cause tsunamis
What movement causes continents to grow outward?
Earthquakes
What causes both earthquakes and volcanoes?
Convection currents.
Are volcanoes and earthquakes manmade?
No. They are caused by the shifting of tectonic plates.
The science that studies earthquakes and their causes?
Seismology is the science of earthquakes and their causes. A scientist who studies earthquakes and their causes is called a seismologist.
What is earthquakes and its causes?
Earthquakes are cool...
What other manmade structures built in ancient times might also is considered Wonders?
Earthquakes and fires
Does deposition causes earthquakes?
i think that earthquakes can cause deposition
What causes a rockfall?
earthquakes

What is the cause for earthquakes in Japan?
The Movement of Techtonic Plates causes the earthquakes in Japan.
Causes of diastrophism?
its is cause of earthquakes
What are the causes and effects of earthquakes?
Earthquakes are caused by faulting, a sudden lateral or vertical movement of rock along the break of the surface - because of plate tectonics. The surface of the Earth is broken up into 'plates', and those plates are constantly shifting against each other. In this way, earthquakes occur. Effects of earthquakes are usually disastrous but it usually depends on the magnitude of the quake. They can include structural damage (to manmade structures), fires, landslides, loss of human and animal life, and tsunamis (or tidal waves).
