If you have any questions about the Science Buddies project that you are working on, please let me know. The USGS also reports on earthquakes around the world. Tips: Make sure students are reading the S waves and not the P waves. When slippage occurred, the phone would record it and you could measure the force or speed of movement. How do scientists measure the size of earthquakes? Student pairs examine seismic waves, S waves and P waves recorded on seismograms, measuring the key S-P interval.
Earthquakes Living Lab: Finding Epicenters & Measuring Magnitudes
What are dip slip s? Even though science cannot predict or prevent earthquakes, what seismological tools do we have to sense the planet's rumblings? The process is called triangulation. Just because something is natural does not mean it is not dangerous. Below is a link to help you get started on your project. The scale moves from white almost zero risk to red very high risk. Alignment agreement: Thanks for your feedback! Describe P wa ves. Use a homemade electronic tester to find out if electricity can flow between two objects. Mapping the history of natural hazards in a region, combined with an understanding of related geologic forces can help forecast the locations and likelihoods of future events.
Seismic Waves: How Earthquakes Move Through the Earth Students learn about the types of seismic waves produced by earthquakes and how they move through the Earth. Source: USGS, Wikipedia S wave: The second seismic wave of an earthquake. That's the way scientists work. Activity Extensions Have student groups explore one or more of the other two regions Southern California and Japan provided in the Virtual Earthquake simulation. You will be referred to a number of specific Internet sites for specific links, but you are welcome to explore other parts of those sites. Why or why not?

Moderators: Hello Corbin: Welcome to Science Buddies. How are earthquakes recorded? Can scientists predict when they will occur? While no one can predict earthquakes, knowing the intensities, frequencies and locations of past earthquakes and fault planes helps us to better anticipate the locations and forces to expect, so we can do our best to prepare our communities and infrastructure to withstand them safely. I have been trying to come up with a physical model for creating such a slip and I envision using two large concrete paving blocks or better, two blocks of marble to serve as the plates. Part 3: Geo g raphy4Kid 's Earth quake s. Engineers first determine where earthquakes are likely to occur, and how severe they are likely to be. They use three seismographs in a process called triangulation to determine earthquake epicenters. What happens when two plates meet? What is an aftershock? What is a main shock? The project you are considering sounds very interesting but setting up a testable hypothesis is going to be a challenge.
Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects. Now on the main page of the Earthquakes Living Lab website see Figure 2 , note the featuring of four active seismic areas and the mapping of real-time and current data from earthquakes happening around the world. Earthquakes Living Lab: FAQs about P Waves, S Waves and More Students learn what causes earthquakes, how we measure and locate them, and their effects and consequences. To answer the two questions, have students each write paragraphs to explain their opinions about the reliability of the science of seismology and ways that engineers use seismic data. Last modified July 18, 2012. Take the earth's energy as an example.
Civil engineers, who design houses, apartment buildings, schools, skyscrapers, bridges, highways, tunnels, water treatment facilities, factories and other structures, may use this data to help them create safer structures that are less likely to sustain damage during earthquakes. What is a foreshock? Short for "secondary wave" or "shear wave. Figure 3: Select the "Chile" box to learn how earthquakes are measured and located. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings. Begin this project by reading about earthquakes here: 1. Why does the earth shake when there is an earthquake? What causes earthquakes and where do they happen? In a concluding class discussion, have groups share their ideas about engineering and one new thing they learned about earthquakes. In this 1-to-10 logarithmic scale, each succeeding level representing 10 times as much energy as the last.
Ask an Expert: What earthquakes tell us about plate tectonics.
Introduction: This lab is to reinforce the information presented in the text and lecture notes about earthquakes and to acquaint the student with the New Madrid Seismic Zone, the earthquakes which have occurred there, and other earthquake phenomena in Arkansas. How are earthquakes rec o rded? Every year, hundreds and sometimes thousands of people are killed because of earthquakes and other seismic events that destroy homes, buildings, cities, and roads. Today, most seismologists no longer follow Richter's original methodology because it does not give reliable results when applied to stronger earthquakes and it was not designed to use data from earthquakes recorded at epicentral distances greater than ~600 km. What does your textbook call dip slips? Alignment agreement: Thanks for your feedback! NGSS Performance Expectation MS-ESS3-2. The living lab presents earthquake information through a focus on four active seismic areas and historic earthquakes in those areas. May want to use the text to answer this. I hope I have given you some ideas to think about.
Thanks for your feedback! As you read and complete the activity, take notes so you can complete the Explain questions next. The moment magnitude scale MMS was developed in the 1970s as a modification of the Richter scale and is better for measuring big earthquakes but less good for small ones. Even though the scale formulae are different, MMS retains the familiar continuum of magnitude values defined by the older scale. What patterns do you see in the distribution of earthquakes around the world? Accessed December 11, 2013. Department of the Interior. How are they the same? Specifically, seismographs make recordings seismograms of the seismic waves generated from earthquakes, providing engineers and other researchers with data that they use to make predictions about future earthquakes.
Source: USGS Assessment Pre-Activity Assessment Introduction: Before student pairs look at the Earthquakes Living Lab, direct them to complete the Engage section of the Activity Embedded Assessment Triangulation and Magnitude: Student pairs complete the Explain portion of the worksheet. How can scientists tell where the earthquake happened? When printing this document, you may NOT modify it in any way. . Using online resources and simulations available through the Earthquakes Living Lab, students explore the consequences of subsurface ground type and building height on seismic d. Being prepared means learning how disasters work and what to expect.
Earthquakes: Are you at risk?
Not what you're looking for? You are on the right track. What is the difference between S and P waves? How is this kind of geological energy different from biological energy such as the calories creatures get when they consume food? Procedure: 1 Read the rest of the information on this exercise BEFORE starting the lab. Can scientists predict earthquakes? It is called triangulation because a triangle has three sides, and it takes three seismographs to locate an earthquake. Can scientists predict earthquakes? Alignment agreement: Thanks for your feedback! An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. The point of origin of an earthquake is called its focus and the point on the Earth's surface directly above the focus is the epicenter.
