  1. The Parkfield Project By: Jeanine Mejares Christina Washington

  2. Basic Earthquake Info • What causes an earthquake? When plates move over, under or slide past each other • Transform • Convergent • Divergent • Where do earthquakes commonly occur? Anywhere in the world- commonly along fault lines • What tools are used to measure an earthquake? • Richter scale- Amplitude of the largest seismic wave recorded. • Mercalli scale- Observations of people

  3. Purpose of our Project • Identify the characteristics (dates, locations, depths, magnitudes) • Scientific reasoning • Inspect recent seismicity • Develop a 3-D visual demonstration organized according to time, location and depth • Draw conclusions: What happened during and after the 2004 Parkfield earthquake?

  4. What’s so Special about the Parkfield Earthquakes? • The sequence of Parkfield earthquakes: 1857, 1881, 1901, 1922, 1934, and 1966 • The 2004 Parkfield earthquake, took place almost a decade later than was predicted

  5. What is the Experiment? • A research project led by the United States Geological Survey (USGS) • Purpose: To discover a basis for earthquake prediction

  6. Procedure • We researched past Parkfield earthquakes • Then we made a prediction of the next giant quake • Next we graphed out earthquakes on a 3-D visualization software • Afterwards we uploaded pictures of Parkfield from before and after the earthquake hit • Finally, we drew conlusions to the main and minor problems of our project 3-D Colorwheel

  7. Along The Way 1990 Earthquake? NO How long? Approximately 14 years Why? No definitive answer Aftershocks? More than a week continuing

  8. Parkfield 3-D Data

  9. Look at that line!

  10. During and After

  11. Video Clip

  12. Conclusion • Pure logic and simple subtraction. With the continuing repetition of the Parkfield Earthquakes, it was evident that an earthquake would occur in Parkfield in approxamitely 1990 • Scientific reasoning, again is a matter of logic and continuing patterns, scientists noticed a rucurring pattern • During the 2004 Parkfield Earthquake, the San Andreas fault ruptured and created a 6.0 magnitude quake, leaving Parkfield with a month of aftershocks
