We always say that displaying data on a map is one of the best ways to bring information to life, especially when the information has a geographical element. One obvious place where this is true is when looking at the pattern of earthquakes. <a title="Bing Maps Silverlight Earthquake Map" href="http://www.earthware.co.uk/demos/slearthquakemapper/indexMarch2011.html" target="_blank"><img style="margin: 10px 15px 10px 0px; display: inline; border: 0px;" title="Bing Maps Silverlight Earthquake Map" src="http://earthware-website.azurewebsites.net/Content/images/wp-images/2011/03/image1.png" border="0" alt="Bing Maps Silverlight Earthquake Map" width="318" height="240" align="left" /></a>The <a href="http://earthquake.usgs.gov/" target="_blank">US Geological Survey</a> publishes a list of recent earthquakes. However, a list doesn’t show the patterns or relationships in the same way that displaying this data on a map will.

Which is why, given recent events in Christchurch and Japan in particular, we have done just this – embedded USGS’s earthquake data in a <a href="http://www.earthware.co.uk/what-we-do/bespoke-mapping-implementations/microsoft-bing-maps.aspx" target="_blank">Bing Map</a> using <a href="http://www.earthware.co.uk/what-we-do/bespoke-mapping-implementations/microsoft-bing-maps-silverlight.aspx" target="_blank">Silverlight</a> technology to create a <a href="http://www.earthware.co.uk/demos/slearthquakemapper/indexMarch2011.html" target="_blank">mapped sequence of earthquakes between 7th and 11th March 2011</a> as recorded by USGS).

In the sequence you can clearly see the build up of earthquakes<a href="http://www.youtube.com/watch?v=qXWrRMk-TAQ" target="_blank"><img style="margin: 10px 0px 10px 10px; display: inline; border: 0px;" title="Japan" src="http://earthware-website.azurewebsites.net/Content/images/wp-images/2011/03/image2.png" border="0" alt="Japan" width="244" height="189" align="right" /></a> in the northern part of the Ring of Fire along the Aeultian Islands starting from the 7th of March 2011.

As well as watching the sequence of events from 7th to the 14th of March 2011, you can experience the last seven days earthquakes or just the last one:
