Ch Person/Attorney Filing: - Superior Court - Maricopa County - superiorcourt maricopa. When the tension becomes too great, the fault slips, causing an earthquake. Using historical seismographs, engineers forecast the strength or magnitude of earthquakes and make predictions and determine building codes and safety protocols. HTn0"H@w=s(vxk8OM1px-{$_!o5|CS7RPr#V(0CUa%ZkuT9t};D Jj=.9,z!#@n5YCu>R88tfFRX=iRK You learned that seismologists determine the distance to the earthquake epicenter using the difference between S and P wave arrival times. Do limits exist on what science can predict? 61 0 obj <> endobj xref 0000006984 00000 n Material is sheared side to side, perpendicular to the direction of wave propagation. Pwaves have the greatest velocity and reach theseismic station first. Short for "primary wave" or "pressure wave." In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; A little under 30 seconds, maybe around 26 seconds. Though they may weaken with distance, seismographs are sensitive enough to still detect these waves. The spot where those three circles intersect is the epicenter (Figure 13.12). For purposes of this activity, the least complicated and probably most accurate approach is to just use the term "magnitude," without needing to say "on the Richter scale" or "on the moment magnitude scale."

How is the magnitude of an earthquake determined? To make a magnitude determination, two measurements are needed: the S-P interval (already determined earlier in the tutorial) and the maximum amplitude of the seismic waves. Resources.

This activity is designed around the Earthquakes Living Lab, a resource and online interface that uses real-time U.S. Geological Survey seismic data from around the world. 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. It travels faster than the same earthquake's S wave (almost double the speed) and is similar to sound waves. Introduction: Before student pairs look at the Earthquakes Living Lab, direct them to complete the Engage section of the Finding Epicenters and Measuring Magnitudes Worksheet, which asks them to apply any prior knowledge and/or speculate as to what the Richter magnitude scale is and what an epicenter is. Section A - Operator Information 1. I contacted the persons listed below to find out the location of the following people entitled to notice Name of Person Measure the difference in arrival times between the first shear (s) wave and the first compressional (p) wave, which can be interpreted from the seismogram. The nations most famous fault is the San Andreas Fault, which runs along a north-south trend in southern California, and happens to run directly through Los Angeles. =Cv :~4yrXP 62{_,*Uq/O-oUNBr-$y~:G},#3e^CS6U*_zVGY7ZNUWk2f?? {%!,"{u5E&OOqA_"/uxn-kx+Vz*EQb)Q To do this, have the students use, Find the epicenter of the earthquake on the map (.
