2 cards from this section. Quick, good the night before a test.
What is an error ellipse?
Think about how we represent uncertainties in measurements.
How does the density of seismic stations affect error ellipses?
Consider what happens when you have more data points.
What do error ellipses represent in epicenter determination?
Think about the concept of uncertainty.
True or False: A larger error ellipse indicates higher precision in determining the epicenter.
What does size signify in our context?
A seismic event occurs, and data is collected from a well-distributed network of 10 seismic stations versus a sparse network of 3 stations. Discuss how the difference in data collection will affect the error ellipses and the confidence in the epicenter determination.
Consider how data quantity can enhance precision.
How might geological structures like mountains and valleys affect seismic wave paths, leading to changes in error ellipse sizes? Provide examples.
Think about how obstacles might alter wave behavior.
