Interactive Quake Maps
Check out a very cool interactive presentation of the recent earthquake events in Japan. The Japan Quake Map is built on Google mapping technology by Paul Nicholls, who also created the Christchurch Quake Map for the recent New Zealand devastation. The map is highly interactive, allowing users to pick a quake from the accumulating list to highlight on the map, and the graphics are coded by color for depth, and size for magnitude. The northwest portion of Japan is taking a beating.
Paul has a second interactive graph showing the total energy released each day and the number of quakes contributing to the total.
For the quake map, set the display options to "Sticky Dots", turn on the quakes and set it to fast forward for an impressive display of the activity since the magnitude 9.0 quake. The data is pulled from the USGS earthquake monitoring system.
