Japanese earthquake – disaster/response maps

Here are some links to maps and map apps related to the Japanese earthquake and tsunami.  I’ll add more as they are released.

  • JapanQuakeMap, an animated, time-lapse visualization of the earthquake and its aftershocks created by Paul Nicholls, developer of the Christchurch Quake Map website.  From the website:
    The Japan Quake Map on this website pesents a time-lapse visualisation of the Sendai earthquake and its aftershocks, primarily to help those outside the affected area understand what the people of Japan are experiencing. It plots earthquake data from USGS on a map using the Google Maps API, with the size of the circle denoting the magnitude (the higher the magnitude, the larger the circle) and the colour showing the focal depth (see the legend below the map).
  • Click here to view the main page for Ushahidi’s Japan crisis mapping tool (in Japanese). Click here to view the Big Map. These pages use the Ushiadi platform to collect and display crowdsourced info (SMS, e-mail, Twitter, Flickr, YouTube, etc.). About the Ushahidi site:

Anyone on the ground can text in the location of a trapped person, and these locations are then collected on a map. You can also text in where to find aid, a pop-up hospital or a precarious building that should be avoided.  Good.is

  • Also from Ushahidi, a Radiation Map that uses the Crowdmap platform.  The radiation map is in both Russian and English and has other language options available.
  • Map of seismic activity in the 7 days leading up to the earthquake – from MapLarge (note: as of Wed. March 16th the MapLarge site is down – too much traffic?)
