Does the drilling of oil and other underground excavations have any significance on major earthquakes?

This question was in discussion and I wondered if this has any bearing.Does the drilling of oil and other underground excavations have any significance on major earthquakes?
I don't know if this copy and paste will help you but I hope so.


';When a certain amount of explosive detonates at a specific depth


below the Earth鈥檚 surface, approximately 20 - 30 per cent of its


energy is utilised in fragmenting the rock or other surrounding


materials. As an explosion is an imperfect use of energy, there is


a loss of energy transmitted through the Earth in the form of


pulsating waves or vibrations. A part of the energy is also


dissipated in the air, which produces noise. Two groups of seismic waves are seen to be generated by detonation of


explosive charges in drill holes, classified as body and surface


waves. Body waves travel within a medium, while surface waves


are restricted to travel along free interfaces, such as the ground


surface. Body waves comprise of two discrete components 鈥?br>

compression or P-wave and shear or S-wave. Two types of


surface waves are usually produced from normal mine blasting 鈥?br>

Rayleigh (R) and Love (L) waves. Other less perceptible waves


are generated also. These waves and their effects on material


properties have been widely discussed in papers from explosives


suppliers and academics. Generally, a blast initially generates


high frequencies which decay into lower frequencies over


distance and the resultant amplitude is greatly affected by ground


conditions and the interaction of the various waveforms.


Wave propagation phenomena were first investigated by


Morris (1950) and his principles have been refined ever since to


attempt to determine peak particle velocity (PPV). PPV is the


unit of measure used for determining the ground vibration effect


of blasting and its formula can be employed to predict vibration


levels using empirical constants and determining the maximum


permissible charge weight per delay. Modern scientific blast


monitoring equipment can measure the actual versus predicted


vibration levels.';Does the drilling of oil and other underground excavations have any significance on major earthquakes?
well not exactly but if u r not careful and go down wayyyyyyyy low than i think it is possible





( i am learning about this : ) )
Oil extraction and mining can and does cause small, local seismic disturbances - HOWEVER: the key words here and small and local. There is no effect on large scale seismic events.
Sure it could just like mining for coal or drilling for gas. They all leave holes or gaps in the ground. Where I am from we have coal mines, and rooms under the ground were the coal was taken out of. If we ever get a earthquake, depending on how many layers and rooms there are we could sink (a room or shaft, up or down is like 6 feet, I am not a coal miner, they would know better) every time we take things out of the earth it will ether leave an open space or water will fill it in. Ether case this makes the ground more unstable. I live where we have very light earthquakes, Eastern Ohio, Northern W. Va., Western Pa. Shake the ground good and look out. This is how I feel.
