Viz: Nine Point Five Earthquake Explorer

The second most powerful earthquake in Virginia's recorded history was felt Tuesday(today) by millions on the East Coast.

I was pretty sure there may already be a visualization for earthquakes and found "9.5 Earthquake Explorer".



http://www.ninepointfive.org/

It presents the most significant earthquakes on the globe. The magnitude of the earthquakes are displayed as particles, lines, rings, or takes you a tour. The higher height or bigger size of these attributes represent more significant earthquakes. The user can select the time range of data to display from 2000 to 2010. It enables to filter the magnitude of the earthquake with a slidebar at the bottom. Zoom-in and zoom-out of the globe are enabled. It also shows the significant earthquakes that occurred recently as a list on the right side of the page. The user may choose one of them which not only turns the globe to the occurred position with the details but also displays a cool effect on the globe.

It is written in WebGL.

The earth imagery and data is from NASA and the earthquake data is from the U.S. Geological Survey.
