Shaking all over: Map of every major earthquake since 1898 reveals stunning image of planet's danger zones

If you are looking for somewhere safe from an earthquake, this might help.

For this map shows the where every major quake has struck since 1898, and as you can see, the edge of the Pacific Ocean appears particularly dangerous. In total there are a staggering 203,186 of them, dotted all over the world.

The neon-coloured map was created as a side-project by mapping manager John Nelson, in a case of taking his work home with him, as he works for data-visualisation software maker IDV Solutions.

John revealed on the IDV blog: 'I've been looking at really general sources of existential risk and visualizing them via the kitchen sink school of thematic mapping.  So the earthquakes map was just a matter of time.

'Here, data from NCEDC.org and the USGS and UC Berkeley have been sliced out into veneers based on magnitude, then glued onto and image that began it's life at Nasa's Visual Earth and wrung into the Times projection (centered at the interesting bits).

'The result looks an awful lot like a fleet of Nickelodeon tankers spilled the world's supply of floam.'

Among the quakes John has mapped are the Great San Francisco Earthquake that killed 3,000 people and last year's disaster in Christchurch, New Zealand, which killed 185 people and destroyed many buildings.

As well as earthquakes, he has also created maps to show the path of each tornado in America over the last six decades using the Fujita Scale, or F-Scale, measures tornadoes based mainly on the amount of damage they cause to buildings and vegetation.

The map, which uses U.S. Government data of where tornadoes 'touched down' between 1950 and 2011, has spread around the world in the last few weeks.

Fuelled by the success of this map, the creator is looking to bring out a new, interactive version, which will include 2012's data and allow you to filter the map by strength, year, location, seasons and other factors.
