(The Steamy Peninsula) is the name of the southwesternmost tip of the
country. The area is and looks very volcanically active and barren. The
most conspicuous are the old shield volcanoes and the crater rows, most
of which probably were created in historical times.
four (or five) volcanic regions are called
Reykjanes-Grindavik-Vogar, Trolladyngja (often split into two
regions), Krysuvik, Brennisteinsfjoll-Blafjoll and Hengill-Selvogur.
The drift zone cuts through all four or five regions and is
the source of frequent earthquakes and high temperature areas have
been created within it, such as at Reykjanes (the heel of the
peninsula), in the Eldvorp area, the Svartsengi area, the Krysuvik
area and the Mt Brennisteinsfjoll area.
