Analysis of tower videos is complete and accurate.

Journal entries on tower testing includes annotated diagrams showing tension and compression and uses data to document and explain what happens to the towers during testing.
Needs Improvement

Analysis of images regarding the modified Mercalli Intensity scale is included with few observations of how the scale helps to inform the design of a building in an area.

Analysis of tower videos is somewhat complete, but missing detail.

Journal entries on tower testing uses data to document and explain what happens to the towers during testing, but may be missing annotated diagrams, or the entries lack detail.
Warning
