If you've not heard there has been a massive earthquake off the North East coast of Japan this morning. This has caused devastation within the region, there are some staggering videos and images emerging. It has also triggered a pacific-wide Tsunami threat which may impact on many regions across that side of the globe. For those of you concerned by these events and keeping an eye on developments you may wish to take a look at an excellent Google Earth plug-in, developed in collaboration with the US Geological Survey, which provides you with a real-time visualisation of the seismic activity overlayed onto the Google Earth interface.

Update: You can see a further collection of maps from the US Geological Society relating to Japan earthquake here.

Naturally my thoughts are with all those affected by this event.
