3D-Graphic of the geology
The threedimensional geological map of Methana by (c) Dr. Lorenz Hurni, ETH-Zurich 1995
The geology of Methana consists about 32 lava domes (andesitic, dacitic) that erupted from 2.000.000 B.C. to 270 B.C. The universitiy ETH-Zurich designed a map of Methana in the size 1:25.000. Also there are some places with sedimentary rocks (triadic, jurassic, cretacious) and carstic systems (caves, katavothres). The digital map data were used to create also the first 3D applications for the use in the internet around 1998-2002.
