My interest in Earth Topology grew considerably since my acquisition of an portable GPS, and I will post here any interesting matters regarding the devices I own themselves; as well as new data I acquire in my travels with them.

Here you will also find the geodetic dataset I used for the creation of the maps in the Links/Geology section, as well as the process I used to create the maps for you to reproduce and revise.

During the volcanic crisis lived in Tenerife during 2004, I found several sites to be of outmost interest:

http://www.todogeologia.com/

The "Diario de un Volcan" blog on the site's forum, being the most interesting to me.

This "Instituto Nacional de Geologia" link has realtime information on seismic events in Spain.

This is the link to the "Guayota" page on the "Instituto Tecnologico y de Energias Renovables" and keeps posted old and new bulletins on the volcanic activity in the archipielago.
