B 4. Seismographs are instruments that record seismic waves. Seismic waves are also of these two types. Presentation Title: What Are Seismic Waves? At such an interface, the energy within an incident seismic wave is partitioned into transmitted and reflected waves. In physics, waves are usually divided into progressive and standing waves. The first set of waves are called P-waves or primary waves. Pressure. Seismic Waves CH 8.2 NCSCoS 2.04 * Imagine two railroad trains leaving the station at the same time on parallel tracks and traveling at different speeds. A 6. – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 7ef08e-Y2E4M `Types Seismic Waves Body waves - arrive before the surface waves emitted by an earthquake. Module 2 The Earth’s Interior Pre-Assessment I. P- and S-waves are referred to as body waves because they are transmitted through the volume (or body) of the material, as apposed to travelling along the surface. Body waves can travel 1. �����%2F�?�k⏆?�|�&���QK���-��. They are the energy that travels through the earth and recorded on seismographs. Present students with the following information, aligned to the slides of the attached PowerPoint file.

The seismic wave speed of a material depends mainly its upon: Temperature. Progressive seismic waves propagate away from seismic sources. Seismic waves tend to slow down as they travel through hot material. Seismic waves are mechanical vibrations that occur inside the Earth. The Seismic Wave Equation Using the stress and strain theory developed in the previous chapter, we now con-struct and solve the seismic wave equation for elastic wave propagation in a uniform whole space. Both types of body waves are non-dispersive (in purely elastic media). Seismic PPT | High-resolution; In addition to body waves, earthquakes also generate surface waves, typically Rayleigh (R) waves. Body waves(P and S-waves) Surface waves(Love and Rayleigh waves) Can be download for class presentation. shock wave. Seismic Waves B 3.

You can think of these waves by picturing the ripples created when a stone is thrown into a puddle or lake. View 12 - Pre-Assessment and Seismic Waves.pptx from SCITECS 2018-2019 at Asia Pacific College. No public clipboards found for this slide. These waves are of a higher frequency than surface waves. The two major types are body waves (S and P waves) and surface waves. This is the fastest kind of seismic wave. They are caused when rock breaks or is deformed. 3 9 customer reviews. �� � } !1AQa"q2���#B��R��$3br� Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within the Earth, whereas the other two, called surface waves, travel along its surface. Many Earth tremors are of such low magnitude they are not noticed by us. See our Privacy Policy and User Agreement for details. Author: Created by alisoncam. Records the movement of Earth in relation to a stationary mass on a rotating drum or magnetic tape Earth structure from seismic waves. Waves generated by an earthquake are called seismic waves. Three Seismic Waves Energy released at the hypocenters of earthquakes travel as three different types of waves. Seismic waves can follow slightly different paths (labeled PKPAB, PKPBC) and still arrive at about the same time. Types of Seismic Waves Seismic waves carry energy from an earthquake away from the focus, through Earth s interior, and across the surface. R waves moving along a stress-free boundary like Earth’s surface induce both horizontal and vertical shaking at the surface. If you continue browsing the site, you agree to the use of cookies on this website. Types `Seismic Waves Body waves - arrive before the surface waves emitted by an earthquake. There are several different kinds of seismic waves, and they all move in PPT. Though they arrive after body waves, it is surface waves that are almost entirely responsible for the damage … Reflection and Transmission of seismic waves in layered media At an interface between two rock layers there is generally a change in propagation velocity resulting from difference in physical properties of the two layers. How Earthquake Waves Provide Information about the Interior of the Earth Seismic ` Waves These are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. ... A colorful and comprehensive PowerPoint highlights this lesson on waves. There is a large amount of geologic activity and movement along the borders of these plates. Measure the interval (in … Richter scale) - based on amplitude of waves with 1s period within 600 km of epicentre. Seismic wave, vibration generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface. Created: Mar 3, 2007 | Updated: Feb 22, 2018. %&'()*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz��������������������������������������������������������������������������� The second ones are called S-waves or secondary waves. - Tsunami - Electromagnetic WAVES; - Applications of EMW - Longitudinal Waves - Transverse Waves - REFRACTION of Waves - DIFFRACTION of Waves Everything is ready to be used or easily edited to suit your learners.

Prepared By: Mark Luwen Borigas Surface waves(L-Waves) - are of a lower frequency than body waves, and are easily distinguished on a seismogram as a result. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.

A 5. Waves and wave motion From the diagram we can see that: The distance between two consecutives nodes is /2 The distance between two consecutive antinodes is /2 The distance between an anti-node and the next node is /4 The Doppler effect is the apparent change in frequency of a wave due to the motion of the source or the observer. Mb=body-wave (similar to above) Ms=surface wave (wave periods of 20s measured anywhere on globe Mo=seismic moment Mw= moment magnitude The Richter scale Steps: 1. The prefix comes from the ancient Greek word ”seismos” which means “to shake”. (slide 1; title slide) Ocean waves and surface waves both propagate from disturbances. When this happens, waves of energy are released and if strong enough, cause the surface of the Earth to tremble noticibly. Characteristics of each seismic waves. Grade 10 - Generosity. An example of a non-elastic wave is a . Different components of the seismic record may be used, including traveltimes, amplitudes, waveform spectra, full waveforms or the entire wavefield.
