“On the 11th of March 2011, the world’s media reported a massive earthquake off the East coast of Japan. It turned out to hit magnitude 9 on the Richter scale, and caused a devastating tsunami; the region’s nuclear power facilities have been experiencing major difficulties since the earthquake and tsunami triggered a series of events leading to massive overheating.

The Japan Quake Map on this website presents 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).” (Japan Quake Map)
