## Data Visualization of Wells, NV Magnitude 6 Earthquake

8s Novice

### How does this data mimic a drop of water in a pond?

This set of animations was inspired by a visualization of ground motion resulting from the February 21, 2008 M 6.0 earthquake that occurred near Wells, NV sending a ripple of ground motion to hundreds of seismic stations. To understand how seismic waves migrate away from an earthquake, we combined the animation at lower right with the image of a faucet to illustrate the classic Earth science functional analogy; “Seismic waves radiate outward from an earthquake’s epicenter like ripples on water”. And then employed Dr. Geophysics to explain the Earth-science concepts in a nutshell.

Exploration of how an earthquake is LIKE ripples on/in water. Dr. Geophysics guides you through the simple physics of potential energy and energy release. Analogies are a useful instructional strategy, especially in the science classroom. In this case, the analog is a drop of water hovering above and then falling into a pool of water, while the target is an earthquake.

Part 2/2 Comparing seismic waves to ripples in water. This animation explores how seismic waves are UNLIKE ripples on water. Dr. Geophysics helps explain 4 significant differences.

Animation Novice

As earthquake waves travel along the surface of the Earth, they cause the ground to move. The ground motions can be captured and displayed as a movie, providing a visual demonstration of these often indiscernible movements.

Working in both small groups and as a whole class, students investigate the classic Earth science analogy: "Seismic waves radiate outward from an earthquake's epicenter like ripples on water". A discrepant image connects the unfamiliar concept of the spreading out of seismic waves to the more familiar scenario of ripples on water radiating outwards in all directions after a droplet falls onto a pool.
