Living in Ottawa, I’ve only felt one at magnitude 5, but it got me thinking that we aren’t entirely stable.
This was a little personal project in using some OSS tools: Data sets from Natural Resources Canada data portal which contains GeoJSON Data embedded in custom data; OpenLayers3 (which is a rewrite of OpenLayers and not backwards compatible) . Try it out here, and grab the source on my Github. Comments and feedback and pull requests welcome.
If you are moving to OpenLayers3, the documentation is autogenerated, but the constructors aren’t really described all that well. The changes were enough to warrant a demo site and a workshop site that cover a lot of cookbook tasks. Find out more about Quakes in Canada at the NRCan quake center. If you want to do something with the datasets at Open Data, you can submit them to their App catalogue here
