• Compare/Contrast s, p and surface waves
• Calculate the distance to an eq epicenter by analyzing s vs p wave graphs
• A question or two about the tsunami lab

If time permits, please return to your write-up for the Shake Table Investigation:

Oh and also, several students have asked about the difficulties in drawing your structure to scale.

• The entire structure must be done accurately, to scale and with straight lines.
• You can use a larger piece of paper (up to 11 x 17) but you MUST include the whole structure on 1 single sheet of paper.

TITLE PAGE:

• All the usual items
• Include table of contents showing each sketch, drawing and the last page for your discussion
• No Abstract

PURPOSE:

The purpose of this activity is to see how tall we can build a structure that will survive a simulated "Full Rip" on the CSZ

METHODS & MATERIALS:

Provide a bulleted list building materials

SAMPLE CALCULATIONS:

None

DATA

A preliminary sketch (freehand) of your shake table - pencil and paper only (min 1/2 page, 1 full page preferred)

DISCUSSION:

Claim: Rewrite the purpose of the lab to clearly and concisely show your concluding statement

Evidence: Refer specifically to your graph and video. Describe how your structure survived (or) or how your structure failed.

Reasoning: Now describe *why* your structure survived or why your structure failed. Be sure to talk like Newton and apply any other physics principles you've learned this year.

Error Analysis: None

Day #1:

Choose materials and make preliminary sketch of your shake table as shown below:

Work on preliminary sketch of your building.

Determine how to attach your building to your shake table.

Day #2:

I need to sign off on at least one person's Engineering Diagram before you begin working on your shake table -- that needs to be done within the first 15 minutes of class.

Begin working on your shake table -- that should be substantially complete by the end of class

If time permits begin designing your building/structure:

• Your goal is to model human built/human inhabited structures. That means no solid block structures whatsoever
• Pay particular attention to how you will anchor your building to your shake table. You might also want to provide a back-up idea in case your primary idea fails during testing.
