Lab Four ¶ Data Analysis ¶
The first thing any researcher wants to do with their data is look it. They want to see if it goes up or down, has any patterns, changes suddenly, or fits a model. Seismology Data ¶
In this lab, we're going to look at data from the U.S. Geological Survey National Strong-Motion Project. Seismology data is an excellent choice for data analysis, for many reasons. The U.S. Geological Survey has done an excellent of making data publicly available, and the data often has a high signal-to-noise-ratio. (Which means you can get an idea of what it's doing without a lot of processing.) Assignment ¶
- Pick a dataset from the Project's list.
- On your wiki page, tell which quake you picked, and link to it.
- Download the corrected and uncorrected accelerations.
- Write a Python module to transform the SMC file into a file with two columns: time and acceleration.
- Plot both versions of accelerations, and their difference.
- How significant is the correction? Does the average change? Does the maximum change?
- Put your plots on your wiki page, and commit any code to the repository.
