Big Thanks btw go to Bastian Holst who has created this nice tutorial.
Vladimir: If you think that the TutorialPlugin wiki can get improved don't
hesitate to make some suggestions or fix the wiki :-)

Well, the very first thing that should also be taken into account is licensing of
Ideally these terms should be as free as possible (and have no "only for non-
commercial use" and no google-style "may only be used in a webbrowser" clause) .
So whatever source you are using please check the legal stuff first. We already
had some incident where we had to basically abandon the Online plugin source
code because of legal doubts. :-(
However with earthquakes I guess this shouldn't be much of an issue, since I
know that such data is offered via US gov sites which usually offer their data
under the FOIA "licensed" under the Public Domain. Still you need to verify
I just found this:
There are two options on this site:
* either parsing of XML (which would be suitable for the OnlinePlugin)
* or usage of the generated KML files. Marble has some capabilities to read kml.
However the kml files there are pkziped kmls and Marble doesn't support this
2.) Geonames is also a pretty cool source for geographic data: They also offer
earthquake webservices: See
The Geonames.org earthquake webservice is using JSON (which we also support in
Marble -- IIRC in the photo plugin):
