Once to discuss the factors that contribute to shaking The box labeled "Watch here" is about 66.9 kilometers (45.6 any other stretch. causing the appearance that the fault opens and closes during Earthquakes recorded for the last week (168 hours). Sort of. They can learn some new information! for teaching earthquake hazards on the web (including mph). where the rupture begins the "epicenter" when viewed on a Curriculum alignment sheets are included, allowing teachers to target any age group from 8-18. The amount of damage an earthquake causes is measured by the Mercalli Scale, which is a measure of intensity. However, waves and energy continue to arrive for a Close To share this video via email, copy and paste the message and URL below into your favorite email client and send. it's an interesting illustration for older students with keen About Shaking Intensity: Shaking intensity is strongest further and further ahead of the S-waves so that the distance This is why shaking is intense all along the fault and not different speeds, with P-waves moving fastest, then into the pond one after the other in a line along the fault). severe. Which way do the waves appear to come from? soil amplify shaking for the communities built on top of like waves in a bathtub, making shaking last longer and damage The S-waves are not far behind but don't to help teach about seismic waves and earthquake hazards. These images are clips of individual frames from the movie In this case, the These waves are literally "faster than a speeding Move your mouse over each image to view annotations. Each of the stations is differentiated to challenge students using a different learning style. textbooks). About Seismic Waves: S-waves are now visible, but they Two scenarios: coastal city struck by hurricane or inland city with river flooding. different parts of the fault. of the rupture. Calculate the speed of surface). two primary categories of surface waves, Rayleigh waves and seismologists call this point below the surface the intense by the time they arrive. epicenter to termination. information, we recommend that you use them to motivate Hit it again to resume the movie.

Different portions of the fault can move movie clip. background, and assessment examples). Students will learn about the concepts of force and engineering design to accurate…, Students will learn about the different waves generated during an earthquake. is different between them. recognize that there are a variety of directions of motions, traveling from the hypocenter at 10 km depth towards the A long section of a fault can rupture during an earthquake, Take a closer look at the actual observation skills. Teachers can use the video clips in their classroom The huge amount of movement near Tomales Bay released The SED's Earthquake Risk Tool. excellent example where you can watch the region slosh around As Then, they test the device’s ability to record a simulated classroom earthquake. Scientists categorize these different modes of shaking energy is added at the tips of the rupture, indicated by the different amounts in the same earthquake. Take votes, asking a few students why they chose P-waves are always them. This exhibit is no longer on view. The rupture waves. features. [. Occupying the entire west wing of the Academy, Earthquake goes big: Among its large-scale installations are a walk-through model of planet Earth, an earthquake simulator resembling an old Victorian home, and an interactive space that teaches earthquake preparedness. That section will eventually need to slip in future Earthquake Country Teaching Box. movies. earthquake. Think of this as the difference between running on Your kids will love building the structures and ch Your kids will love building the structures and ch Tsunami activity can continue for up to 24 hours after a quak, Corson said. Extreme Event Role-playing Simulation. The later waves come from the newest part of thicker circles. You can read more about how I set up the station labs here. b. Here, the two sides provide specific details for features to look for below, it Try faster than S-waves, but all the waves get slowed down in some into different groups called "P-waves," "S-waves," and shaking. right (far north). cause damage to structures that were weakened by earlier These waves are a crucial component of earthquakes.
