ISS016-E-008436 (26 Oct. 2007) --- Beirut Metropolitan Area, Lebanon is featured in this image photographed by an Expedition 16 crewmember on the International Space Station. The capital of Lebanon, Beirut is located along the southeastern shoreline of the Mediterranean Sea. According to geologists, the metropolitan area is built on a small peninsula composed mainly of sedimentary rock deposited over the past 100 million years or so. The growth of the city eastwards is bounded by foothills of the more mountainous interior of Lebanon (sparsely settled greenish brown region visible at upper right). While this sedimentary platform is stable, the country of Lebanon is located along a major transform fault zone, or region where the African and Arabian tectonic plates are moving laterally in relation to (and against) each other. This active tectonism creates an earthquake hazard for the country. The Roum Fault, one of the fault strands that is part of the transform boundary, is located directly to the south of the Beirut metropolitan area. Other distinctive features visible in this image include the Rafic Hariri Airport at lower right, the city sports arena at center, and several areas of green and open space (such a large golf course at center). Also visible in the image are several plumes of sediment along the coastline -- the most striking of which are located near the airport. The general lack of vegetation in the airport may promote higher degrees of soil transport by surface water runoff or wind.
