Seismic wave

Have you ever thought of how scary nuclear testing in North Korea could be very scary? To you, nuclear testing may be no big deal. But, to others in our country it is very nerve racking for everyone. You never know where the bombs may end up. They could even be planning a secret attack on someone and nobody will know. In 2006, 2009, 2013 they tested atomic bombs every one of those years in North Korea. Nuclear bombs can be very powerful and even deadly to many. In 1961 it remained the most…

Discussion Points 1. Do some Internet research on Chevron’s use of seismic imaging technology? Briefly explain how it works and how it has helped Chevron discover new oil and gas reservoirs. Seismic waves are used to study earthquakes. Seismic imaging technology is widely used to explore underground oil and gas reservoirs by sending sound waves by ultrasensitive device, geophones which detect the appropriate location of oil and gas. This technology is successful in tapping the locations for oil…

They have large ears that function in many ways, specifically in the detection of vibrations and seismic cues due to their ear structure that have three essential parts: the outer ear which captures sounds, a middle ear which filters and amplifies sound, and the cochlea (the inner ear) which is a band-pass filter and transducer of sound into neural impulses…

mammals, 5, 401 birds, and 553 sea turtles” (Mooney, 46). Oil spills kill thousands of birds and fish. The integrity of the ocean water is depleted. Not only do oil spills affect marine ecosystems, but seismic testing is harmful to any marine mammal dependent on sound. Seismic testing shoots sound waves that can go through ocean depths and 500…

Tsunamis can start from anything that suddenly displaces the seafloor, causing water to compensate for it (Kusky, 2008, p.1). Tsunamis can also be referred to as seismic sea waves. Two tsunamis occur per year around the world, and one very destructive one every 15 years, on average (Department of Homeland Security, n.d.). One specific tsunami happened in the Pacific Ocean near Chile on September 16, 2015. A tsunami can cause massive damage, wreak havoc, and ruin anything it gets near. Some do…

technique senses the thermal emission from the body at wavelengths greater than 8 microns, revealing the temperature of the body. Infrared light can also be applied as a heat treatment to patients. 9.Please explain, what is the wavelength of the carrier wave used by your favorite radio…

1. What are Seismic Imaging Technology and Chevron use of the technology? Seismic Imaging is a tool/technique to find the availability of crude oils and natural gas underground. It is also known as reflection Seismology as it is a process of inspection geophysics to evaluate the properties of Earth’s subsurface by using the principles of seismology from the reflected seismic waves. Sound waves are recorded by Seismologists using an ultrasensitive device called geophone as they echo under the…

Canada is located near and on many fault lines. With fault, lines energy builds up and has to be expelled in the form of an earthquake. The regions for seismic activity in Canada are: the Cordillera region, British Columbia, the Arctic and to a smaller extend, and central Quebec. More than 4,000 earthquakes occur in Canada every year. The western regions are the most seismically active region in Canada. More than 100 earthquakes with a magnitude of 5 or more have occured in Canada over the past…

survey. The seismic survey determines the estimated reserve in the area, and the best locations to drill. The experts test the area for pre-existing seismic faults, ground water, and oil and gas deposits. The test begins by creating a small shock wave on the surface with either an explosive buried in the ground, or a “stomper” truck that vibrates the ground. When the shock waves strike items of different densities they reflect back to surface at different rates. On the surface, the shock waves…

Plate tectonics theory is essentially that the earth made up of different plates that move and cause seismic activity like earthquakes (Tarbuck & Lutgens, 2015). Earthquakes occur on plate boundaries, which is the area between the many plates that make up the earth’s lithosphere. There are 3 types of plate boundaries: divergent, convergent and transform…
