Earthquakes & tectonic plates on Selborne


The latest addition to Selborne is earthquake data. To be frankly honest: the relevance of this to a personal environmental data annotation website is only partly there but the data is out there, reliable, and easy to use. There are links in the menu that will add all earthquakes from the last hour, day, week & month. 

There are plenty of websites where said earthquake data can be watched. What I never recall seeing with it is data on plate tectonics. These I have also added. There are links for ridges, trenches, transforms and a link for all of them together. There is also a link to view all earthquakes of past week with plates. 

Another tiny addition is a link to show Vavilov's 'centres of origin', the regions where crop domestication is thought to have originated. I created this by drawing copying it on the map from a map provided by Wikipedia. You can do nice things like view these with the Steppe data from the terestrial ecoregion data and watch a historical pattern in action.

When viewed on its own you can see what each ridge, trench & transform is called.
