Class Summary – 28 Mar – Earthquake Damage Case Studies
I reviewed the impact of shaking on human-built structures, presenting examples of the types and amount of damage that the strong shaking near a strong earthquake can produce.
No in-class exercise.
Class Summary –18 Mar – Location and Magnitude
We discussed Wednesday’s M7.3 earthquake off the coast of Japan.
I lectured on some things we can do with an understanding of seismic waves and seismograms – location and magnitude. Students completed the in-class exercise on location, and took the exercise on magnitude home to complete (as a homework).
Class Summary –16 Mar – Seismograms and Seismic Waves
I reviewed the four types of seismic waves and how to “read” seismograms.
Students completed an in-class activity related to reading seismograms.
Class Summary – 14 Mar (π-day) – Observing EQ: Seismic Intensity
I reviewed seismic intensity measures, older, but still relevant measures of the damage and impacts of earthquakes that provide one way to compare historic and modern earthquakes.
Students complete an in-class exercise related to the 2016 Pawnee, OK earthquake and the information available for significant earthquakes on the US Geological Survey web site.
