Flash Interactive Exercise: Creating a step-by-step, process-type infographic
(Content from the BBC. To be used as a class exercise only)
Explain how a tsunami is created and can cause widespread devastation in an interactive infographic. Viewer can click a button to navigate to each stage of the process to view the image and read the text. Design the layout, your individual buttons, and distribute the content (the images and text) along keyframes on the Timeline.

Subhead: Moving Plates
Tsumanis are caused by earthquakes at sea. Earthquakes happen when the plates that make up the Earth’s surface suddenly move against each other.
Subhead: Displacement of Water
A tsunami forms when energy from an earthquake vertically jolts the seabed by several meters, displacing hundreds of cubic kilometers of water.
Subhead: Waves Form
Large waves begin moving through the ocean, away from the earthquake’s epicenter.
Subhead: Waves at the Coast
When the tsunami reaches shallow water near coastal areas, the tsunami slows but increases in height.
Subhead: Kalutara Before
Coastal areas like the Sri Lankan tourist resort of Kalutara, as seen in this satellite picture, had almost no warning of the approaching tsunami on December 26, 2004.
Subhead: Kalutara During
The only sign came just before the tsunami struck when the waterline suddenly retreated, exposing hundreds of meters of beach and seabed.
Subhead: Kalutara Impact
The several waves of the tsunami came at intervals between five and 40 minutes. In Kalutara the water reached at least 1km (0.6 miles) inland, causing widespread destruction.
