The Parkfield Project
By: Jeanine Mejares Christina Washington
Basic Earthquake Info• What causes an earthquake?
When plates move over, under or slide past each other 1. Transform2. Convergent3. Divergent
• Where do earthquakes commonly occur?Anywhere in the world- commonly along fault lines
What tools are used to measure an earthquake?
1) Richter scale- Amplitude of the largest seismic wave recorded.
2) Mercalli scale- Observations of people
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?
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

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

Along The Way1990 Earthquake?
NO
How long?Approximately 14 years
Why?No definitive answer
Aftershocks?More than a week continuing

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

THANK YOU!!!
When will the next Parkfield quake
occur?
