Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects. A seismograph is securely mounted onto the surface of the earth so that when the earth shakes, the entire unit shakes with it EXCEPT for the mass on the spring, which has inertia and remains in the same place.

The western U.S. has more faults than the eastern U.S., and therefore the western U.S. has more earthquakes. All rights reserved. inch = 500 km. First, determine the P-wave arrival, and read down to the bottom of the seismogram to note at what time (usually marked in seconds) that the P-wave arrived. seismogram. A minimum of three seismic stations is necessary to locate an epicenter. [N'. Mr Gneiss. HTAn Quick Tips. 1. Using the real-world data in the living lab enables students and teachers to practice analyzing data to solve problems and answer questions, in much the same way that scientists and engineers do every day. The process is called triangulation. Use of the TeachEngineering digital library and this website constitutes acceptance of our Terms of Use and Privacy Policy. The real-world earthquake data is viewable via a graphical interface using a scaling map. Notify the classroom teacher of technology needs (overhead projector). Figure 2. 11 minutes elapsed between the first P wave and the last measurable surface wave.

In this 1-to-10 logarithmic scale, each succeeding level representing 10 times as much energy as the last. Then locate and click the link in the center of the page under the question: "How is an earthquake epicenter located and how is magnitude determined"? Students learn what causes earthquakes, how we measure and locate them, and their effects and consequences.

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. It is called triangulation because a triangle has three sides, and it takes three seismographs to locate an earthquake. 0000002507 00000 n
Explain the difference between S and P waves, and how their time interval is used to determine the epicenter location. Engineers first determine where earthquakes are likely to occur, and how severe they are likely to be. Once three seismographs have been located, find the time interval between the arrival of the P-wave . How does the Mad Scientist. HlRnQ?R\>BjK' 0000106240 00000 n

Learn more How Can I Locate the Earthquake Epicenter? Earthquakes and Seismic Waves Key Concepts . What is an earthquake? The instrument detects and documents the intensity, direction and duration of ground vibrations, which are used to determine the epicenters and strength/magnitudes of earthquakes or other seismic events.

In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
important in helping seismologists determine the epicenter of the earthquake. Before going to the classroom, you will need to: Provide each student, with the following: Earthquakes occur every day all over the United States and all over the world. 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. Section 8.1 What Is an Earthquake? 0
