     Extractions: Earthquakes II Table of Contents Summary Measurement of Earthquakes Modified Mercalli Scale Richter Scale ... Appendix Summary This lecture discusses how earthquakes are measured and examines the global, national and regional distribution of earthquakes. After reviewing this material you should know: What methods can be used to measure an earthquake? What is the difference between earthquake intensity and magnitude? How is the Modified Mercalli scale used? What regions of the U.S. have a history of earthquake activity? What is the difference between great, major, and strong earthquakes? How is the Richter scale used? How many earthquakes occur each year? Where have the most recent earthquakes occurred in the U.S.? Is there a difference in the distribution of deep and shallow earthquakes? Does Ohio experience earthquakes?

103. Activity #3 -- Measuring Earthquakes
     Section 3 Measuring Earthquakes To locate earthquakes in this activity, youwill need to align the red arrow on each trace with the time of the Pwave

     Extractions: Section 3: Measuring Earthquakes Concept: Both the epicenter and origin time of an earthquake can be located with computations involving the exact arrival times of seismic waves at three or more seismometers. These arrival times can be picked by analyzing the waveforms recorded on seismograms. Materials: a frames- and layers-capable browser Procedure: The purpose of this activity is to learn how analysis and measurement of seismograms from three or more seismometers can, with relatively simple mathematical calculations, yield the map locations the epicenters of earthquakes. The online section of this activity will allow you to interactively analyze real seismic data from several earthquakes that have occurred in southern California. You will be picking the arrival times of the two body waves the P wave and the S wave and then, using travel-time circles on a map of southern California as your guide, marking the location you believe represents the epicenter of the earthquake. Your wave-arrival picks will also be used to calculate the origin time of the earthquake. Should your first attempt to pick the arrival times produce unsatisfactory results, you will be able to revise them, and see the changes in time and location produced by the changes in your picks. In fact, there is no limit to the number of times you can revise your analysis of the seismograms provided. This page will help you get started by previewing the basics of the activity. The

     Extractions: This Week Inventor Archive Inventor Search Inventor of the Week Archive Browse for a different Invention or Inventor Seismograph Geologist and engineer John Milne is known as one of the most significant contributors to the understanding and evaluation of earthquakes, having compiled a substantial body of observational research, developed the first international network for seismological data, and created what may be considered the world’s first modern seismograph. Born on December 30, 1850 in Liverpool, England, Milne attended King’s College and the Royal School of Mines where he earned the credentials to become a mining engineer. He first began working in Europe, performing mineral investigations for mines there and later, in Newfoundland. He also participated in an 1874 mining expedition to Sinai. At the age of 25, he accepted a professorial post at the newly established Imperial College of Engineering in Tokyo. He took an adventurous 11-month overland journey to get there, traveling across Siberia and arriving in Japan in 1876. An earthquake occurred there on his very first night. The study of earthquakes was relatively new then, having become a field of its own only in the mid-18th century, when a series of major quakes that hit England in 1750 was followed by a quake and tsunami in 1755 that devastated Lisbon, Portugal, killing nearly 70,000. At this time scientists began compiling observational data on quakes around the world, and as international communications improved, more and more information could be combined.
