	Background
	Current Research, Phase I
	Future Work, Phase II & III

	Need a new approach in vibration monitoring
		Current practice
			Measure ground motion and compare with house damage from past studies
		People see cracks in there houses
			Don’t understand ground motion
			Despite past evidence difficult to convince

	Create a system that will:
		Measure change in crack width due to both long term and dynamic effects
		Compare changes in crack width with temperature, humidity, and dynamic excitation
		Comparison should be
			Accessible easily to general public
			Regenerated often
			Graphically presented

	Hardware
	Automation of System
	Test House Data
	Web Site

	LVDT’s

	Electronic Drift
	Thermally Induced Hysteresis

	Null Sensor
		Near-by but not Across the Crack

	Graphical Interface Easily Understood by the Lay Public
		Quick Loading
		No Scrolling
		Consistent Feel
	Viewable on any browser
		Compatible with older computers
	Easily Extensible
		New Pages will be added in the Future

	Background Information About Crack Movement
	Location
		Sensors in House
		House in Neighborhood
	Weather Information
		Temperature
		Humidity
	Crack Displacement Information vs.
		Weather
		Vibration

	Crack Width Changes are Effected
		Most by Weather
			Humidity
			Temperature
		Moderately by Habitation Vibrations
			Near by – walking down stairs
			Far away – slamming a door across the room
		Least by Construction Vibration
			Blasting
			Pile Driving
			Etc.
	System that Works!!
		Autonomously Records, Analyzes, and Displays Data

	Sensors
		More Research Into Better Sensors
	Web Improvement
		Security
		Web Interactive Components
			Graphical Tutorials
			Self Guided Tours of Background Information
		Addition of Blast Induced Vibration
			Transducers
			Additional Programming
