Almannagjá
Iceland

Almannagjá is a vast gorge, distinctive demonstration of a fault which marks the west part of a Þingvellir rift zone. It is one of a few places when one can easily walk inside a ridge zone normally hidden deep in worlds oceans. It is spreading with a constant rate of two centimeters per year. Unfortunatelly this movement is not smooth, it is rather done in big steps - earthquakes. Last tectonic activity was recorded in 2000. From time when Alþing was established in 930 the inside part of zone subsided to almost four meters.

More About Europe

Europe is generally agreed to be the birthplace of western culture, including such legendary innovations as the democratic nation-state, football and tomato sauce.The word Europe comes from the Greek goddess Europa, who was kidnapped by Zeus and plunked down on the island of Crete. Europa gradually changed from referring to mainland Greece until it extended finally to include Norway and Russia.Don't be confused that Europe is called a continent without looking like an island, the way the other continents do. It's okay. The Ural mountains have steadily been there to divide Europe from Asia for the last 250 million years. Russia technically inhabits "Eurasia".Europe is presently uniting into one political and economic zone with a common currency called the Euro. The European Union originated in 1993 and is now composed of 27 member states. Its headquarters is in Brussels, Belgium.Do not confuse the EU with the Council of Europe, which has 47 member states and dates to 1949. These two bodies share the same flag, national anthem, and mission of integrating Europe. The headquarters of the Council are located in Strasbourg, France, and it is most famous for its European Court of Human Rights. In spite of these two bodies, there is still no single Constitution or set of laws applying to all the countries of Europe. Debate rages over the role of the EU in regards to national sovereignty. As of January 2009, the Lisbon Treaty is the closest thing to a European Constitution, yet it has not been approved by all the EU states. Text by Steve Smith.
