The Tectonics of Greece

In a tectonically active region, the Earth's crust is subject to strong forces causing it to deform. In the case of Greece, the region is being pulled apart (it is extending), and we can see this extension in the topography of the landscape.

Satellite images are an ideal tool for studying the topography of a region because they cover large areas and contain detailed information. The images in this area of the site are Thematic Mapper (TM) images from the Landsat 5 satellite (shown on this page).

Each image contains information on seven different wavelengths, which can be combined to highlight different surface features such vegetation and rock type. The images are a combination of one visual and two infrared wavelengths shown in red, green and blue.
