Seven days after the devastating Japan Earthquake the number of aftershocks keeps adding up. I’ve updated my earlier animated quake map to reflect this. Keep an eye on the count in the top right hand corner.
For a different take on this check out Jeffry Friedl’s animation. In addition to mapping aftershock epicentres he visualizes thousands of accelerometer readings around Honshu. Accurately representing just how strongly the ground movement would have been felt in different locations.
Last but certainly not least, the Japan Quake Map allows you to play back the time line of seismic events over a Google Map and interact with the data. Change the range of dates shown or alter the playback speed.
