Seismic wave

understand the dynamics of the Earth’s mantle are seismic snapshots and computer modeling. Seismic snapshots enable scientists to determine the temperature and density of the mantle. When an earthquake occurs vibrations are put into motion which create waves that can be detected by apparatuses, seismic waves. Using the instruments that are set up around the world, Geologists and Geophysics determine the amount of time it takes for the seismic wave to travel from the epicenter of an earthquake…

Ground motion is when the shaking of the ground causes the passage of seismic waves, especially surface waves, near the epicenter of the earthquake. Ground motion is responsible for the most damage during an earthquake and is thus a primary effect of an earthquake. Aftershocks are smaller earthquakes that occur after a main earthquake, and…

As human, we used to think ourselves as a superior species with the power to control and manipulate nature as we wish, but in fact we are very vulnerable to natural disasters like volcano, typhoon, tsunami and especially earthquake. For the last decade, we had to face with many super earthquake with magnitude from 7.0 to 9.0 Richter which caused devastating damage, some even send a country backward 10 years in development like Haiti earthquake in 2010 according to the UNICEF. With the power of…

There are two main ways scientist learn of earth saunterer is rock samples are rock sample from looking at the rock that comes from defence babanic explosion. The second main ways selected learn about earth centered is seismic waves seismic waves inderal travel thpro put where they travel speed path. Inconclusive this is how scientists learn about earth centered Crust Mantle and Core There are 3 layer of the crust mental and care. The crust is a layer that we stand on and a…

well as killing 160 people. The cause of this was an undersea earthquake off the Alaskan Coast. (This Day in History) “…13,000 feet beneath the ocean surface, a 7.4-magnitude tremor was recorded in the North Pacific.” A tsunami is a series of large waves generated by an abrupt movement on the ocean floor which could be caused by an earthquake. “However, powerful undersea earthquakes are responsible for most tsunamis,” states Voa News (What Causes a Tsunami?). Tsunamis have the power to, not only…

They are texts written by qualified professionals in the field so are very valuable and valid source of information and are frequently used as learning resources. Many texts and journals have been written in relation to seismic activity and the consequences that come from it. They also have many factors that make them both a very good source and a very bad source. The fact that academic journals are specially designed to talk about the specific topic means that they contain…

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 imaging is a tool that reflects the waves off the underground rock structures to show the possible crude oil and natural gas that are present underneath. People use the ultrasensitive devices that is called as geophones to capture the sound waves as they echo underneath the earth. So by studying those echoes,…

the magnetics properties of the nucleus. 2. Sound waves are longitudinal waves and they produce alternately states of compression and rare fraction at a point in a medium. Therefore when two sound waves of equal frequency travel simultaneously in a medium in the same direction then at some idea both waves produce compression that is they meet in the same place. At these points the amplitude is equal to the sum of the amplitudes for the two waves and the intensity of the sound is maximum. On…

The design of this report is to show the is to show the written report of an earthquake occurring either on the San Andreas Fault Line or the Hayward Fault Line. Designing bridges and seeing if the bridge that was built to survive an earthquake with the magnitude of 5.0-8.0 for Hayward and for San Andreas 5.0-9.0 the power of these earthquakes have the power to destroy lots of things at once. Some earthquakes are not noticeable but it 's the fact that earthquakes are so powerful that it can go…

One of the subfields of seismology is to study how and why earthquakes occur. Predicting and projecting when, how, and why earthquakes occur can save millions of lives, while also saving billions in public taxpayer funds to rebuild after the damage. There are several types of gravitational forces that occur within the earth and cause earthquakes, such as plate tectonics and seafloor spreading. Understanding these actions can allow us to have better understanding of the causation of earthquakes.…
