OPENING QUESTIONS:
The cliffs & bluffs around Puget Sound are prone to collapse from time to time. Work with your team to sketch such a cliff here in the Narrows.
Be sure to sketch all the way from the top of the cliff to the bottom of the sound.
LEARNING TARGET: I will evaluate the impact of Puget Sound landslides on the formation of tsunami waves during today's class.
WORDS O' THE DAY:
WORK O' THE DAY:
There was a M 6.8 earthquake centered in Nisqually in 1949 (nearly identical to the 2001 earthquake). That even loosened up already unstable parts of the bluffs above the Narrows on the Tacoma side-- resulting two or three days later in the landslide shown below
Here is the geophysical data of that situation

Work with your team and find historical information about the slide -- VERY briefly

Now let's flip our sheets over and draw a more accurate representation of that slide in light of the project which we will begin... now!
Probably the MOST important aspect of all of our conversations regarding waves (Ocean Waves, Tsunami Waves, Megatsunamis waves, Earthquake Waves, Light Waves etc...) is that waves always carry energy, not particles.
Towards that end we are going to make our best efforts at measuring the amount of energy *imparted* to Puget Sound as a result of all that material sliding into Puget Sound.
