A The focus of the earthquake is directly below the epicenter. A 29. Principle(s) Investigated: Energy transmission by seismic waves, differences in wave movement and effects, elastic rebound/plate motions, waves in all directions and differences in travel times compared to distance.. Standards: 1.g. This animation, called a Ground Motion Visualization (GMV), shows the motion of the ground as detected on seismometers across North America - each dot is a seismic station and when the ground moves up it turns red and when it moves down it turns blue. Surface Waves • Move along the Earth’s surface • Produces motion in the upper crust – Motion can be up and down – Motion can be around – Motion can be back and forth • Travel more slowly than S and P waves • More destructive Animation of wave types 20. – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 7ef08e-Y2E4M ... the level of damage each wave might cause in a residential area and test their predictions against several computer animations. B 28. The latest earthquakes on a map with news, lists, and links. The last type of earthquake wave to hit seismic stations is the surface wave. A visualization of earthquake waves traveling both through Earth's interior and radiating outward on the surface. Press the play button to begin. Surface waves move back and forth in a swaying motion in all directions. The focus is the origin of the earthquake Seismic Waves. PART I: Introduction to the Animations 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. This wave behaviour can also be used on a smaller scale by recording waves generated by explosions or ground vibrators in the search for oil and gas. Rayleigh Wave (R-Wave) Animation. Seismic waves travel fast, on the order of kilometers per second (km/s). Animations of water waves‎ (2 C, 7 F) Media in category "Animations of vibrations and waves" The following 150 files are in this category, out of 150 total. This animation produced in conjunction with KQED's QUEST Series, walks viewers through an easy to understand, playful introduction to Earthquake basics and various different seismic waves. Click to see the animation. The wave is seen as the motion of the compressed region (ie, it is a pressure wave), which moves from left to right. Deformation propagates. While textbooks describe how P waves are faster than S waves that in turn are faster than surface waves, this animation of seismic waves generated by the Mariana Islands earthquake visually reinforces these observed seismic wave velocities. Seismic Refraction (SR) is a surface geophysics method that utilizes the refraction of seismic waves on geology layers and rock/soil units to characterize subsurface geologic conditions. The lines represent P-waves radiating out from the earthquake. Seismology is the study of earthquakes and seismic waves that move through and around the earth. An earthquake generates a series of seismic waves that travel through the interior or near the surface of the Earth. Large low-shear-velocity provinces, LLSVPs, also called LLVPs or superplumes, are characteristic structures of parts of the lowermost mantle (the region surrounding the outer core) of Earth. In a homogeneous medium, a surface drawn through points of equal travel time is spherical, as depicted in the animation below. P-waves and S-waves are sometimes collectively called body waves. What you will see is explained here. No membership needed. Key 21. types of seismic waves. Animation 3: Seismic Waves. The different colors of the lines represent the velocity of the waves: Note that the lines turn blue as they cross t No membership needed. Seismic wave residential building icon animation - download this royalty free Stock Footage in seconds. P-waves Amplitude decreases with depth. Mapa de últimos terremotos incluso boletines, noticias y enlaces. A 30. Slides for PowerPoint - Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. Making Waves: Classroom Demos and Activities for Teaching About Seismic Waves 1 Larry Braile, Purdue University braile@purdue.edu, web.ics.purdue.edu/~braile S… Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Of the body waves, the primary, or P, wave has the higher speed of propagation and so reaches a seismic recording station faster than the secondary, or S, wave. Learn More. And just to be clear, seismic waves, they're normally associated with earthquakes, but they're any waves that travel through the Earth. These provinces are characterized by slow shear wave velocities and were discovered by seismic tomography of deep Earth. Richter scale: The Richter magnitude scale provides a measure of the intensity of earthquakes on a 1 to 10 (base-10 logarithmic) scale.
