  • New Empirical Relationships Among Magnitude, Rupture Length, Rupture Width, Rupture Area, and Surface Displacement
    Bulletin of the Seismological Society of America, Vol. 84, No. 4, pp. 974-1002, August 1994 New Empirical Relationships among Magnitude, Rupture Length, Rupture Width, Rupture Area, and Surface Displacement by Donald L. Wells and Kevin J. Coppersmith Abstract Source parameters for historical earthquakes worldwide are com­ piled to develop a series of empirical relationships among moment magnitude (M), surface rupture length, subsurface rupture length, downdip rupture width, rupture area, and maximum and average displacement per event. The resulting data base is a significant update of previous compilations and includes the ad­ ditional source parameters of seismic moment, moment magnitude, subsurface rupture length, downdip rupture width, and average surface displacement. Each source parameter is classified as reliable or unreliable, based on our evaluation of the accuracy of individual values. Only the reliable source parameters are used in the final analyses. In comparing source parameters, we note the fol­ lowing trends: (1) Generally, the length of rupture at the surface is equal to 75% of the subsurface rupture length; however, the ratio of surface rupture length to subsurface rupture length increases with magnitude; (2) the average surface dis­ placement per event is about one-half the maximum surface displacement per event; and (3) the average subsurface displacement on the fault plane is less than the maximum surface displacement but more than the average surface dis­ placement. Thus, for most earthquakes in this data base, slip on the fault plane at seismogenic depths is manifested by similar displacements at the surface. Log-linear regressions between earthquake magnitude and surface rupture length, subsurface rupture length, and rupture area are especially well correlated, show­ ing standard deviations of 0.25 to 0.35 magnitude units.

  • A Storm Is Coming! Lessons in Hurricane Preparedness
    A Storm is Coming! Lessons in Hurricane Preparedness Georgia Redonet Long Middle School INTRODUCTION The busy 2004 hurricane season, with fifteen Atlantic storms certainly served to remind us that we should learn the essentials of hurricane preparedness. I find that a study of hurricanes and their effect on our state’s coastal areas provides an exciting and interesting start to the school year in my seventh grade Texas History classes. We study the causes and effects of the storms and how to prepare for emergency situations. While this unit will focus only on hurricane preparedness, in the classroom we will first study the formation and structure of hurricanes and round out our studies by investigating the Great Galveston Storm of 1900. I would suggest that those teachers living in coastal areas choose a storm from their own locale. When there was the possibility that our area might be struck by an approaching storm, as was the case with Ivan in September 2004, the energy level in my classroom was electrifying. Students eagerly watched the news and weather and were going to the school computer lab to check out weather web sites. On May 24, 2005, the American Red Cross reported that they had found many Americans in coastal regions who were not prepared for the coming hurricane season that lasts from June 1 to November 30: Waiting until the last minute to prepare for a hurricane, or assuming that a major storm will not hit your community is a mistake, said Joe Becker, Senior Vice President, Preparedness and Response for the American Red Cross.

  • Creating Educational Media for Students in the United Kingdom
    CREATING EDUCATIONAL MEDIA FOR STUDENTS IN THE UNITED KINGDOM An Interactive Qualifying Project Report submitted to the faculty of WORCESTER POLYTECHNIC INSTITUTE in partial fulfilment of the requirements for the Degree of Bachelor of Science By _____________________________ Nicholas Baker _____________________________ Allyson Barford _____________________________ Seth Borg ___________________________ Elizabeth Heneberry Date: March 1, 2002 Approved: _____________________________________ Professor Gregory Theyel, Major Advisor _____________________________________ Professor Stephen Matson, Major Advisor Authorship We, the Science Year IQP team submit that this report and our project work reflects a collaborative team effort from all four group members. 1. Abstract The WPI Science Year IQP intends to contribute to efforts to revitalise interest in science among students ages ten to nineteen by capturing their attention and interest with interactive web-based computer games focusing on the popular themes of sports and inventions. In developing these games, the project team researched student interest in science and web- based games, the UK national curriculum, and educational game design and production. Final deliverables include comprehensive game design documents, detailed storyboards, and two Flash-based Internet games. 2. Executive Summary Educators and industry representatives in the United Kingdom have expressed concern about the decline of interest in scientific study among children and young adults between 10 and 19 years of age. Resources and initiatives are needed for making science provocative and exciting to today’s youth. Science Year is a UK government-based initiative that seeks to spawn interest in this target age group through various educational resources such as web-based games, nationwide projects, and CD-ROMs for use in the classroom.

BOORE US Geological Survey, 345 Middlefield Road, MS 977, Menlo Park, CA 94025, USA Large modifications of seismic waves are produced by variations of material properties near the Earth’s surface and by both surface and buried topography. These modifica- tions, usually referred to as “site response”, in general lead to larger motions on soil sites than on rock-like sites. Because the soil amplifications can be as large as a factor of ten, they are important in engineering applications that require the quantitative spec- ification of ground motions. This has been recognised for years by both seismologists and engineers, and it is hard to open an earthquake journal these days without finding an article on site response. What is often missing in these studies, however, are discus- sions of the uncertainty of the predicted response. A number of purely observational studies demonstrate that ground motions have large site-to-site variability for a single earthquake and large earthquake-location-dependent variability for a single site. This variability makes site-specific, earthquake-specific predictions of site response quite un- certain, even if detailed geotechnical and geological information is available near the site. Predictions of site response for average classes of sites exposed to the motions from many earthquakes can be made with much greater certainty if sufficient empirical observations are available. Keywords: Site response; amplification; transfer functions; ground motion; variability; prediction. 1.
