Dubai, United Arab Emirates

Dubai is situated on the Persian Gulf coast of the United Arab Emirates and is roughly at sea level (16 m/52 ft above). The emirate of Dubai shares borders with Abu Dhabi in the south, Sharjah in the northeast, and the Sultanate of Oman in the southeast. Hatta, a minor exclave of the emirate, is surrounded on three sides by Oman and by the emirates of Ajman (in the west) and Ras Al Khaimah (in the north). The Persian Gulf borders the western coast of the emirate. Dubai is positioned at 25.2697°N 55.3095°E and covers an area of 4,114 km² (1,588 mi²), which represents a significant expansion beyond its initial 1,500 sq mi (3,900 km2) designation due to land reclamation from the sea.
Dubai lies directly within the Arabian Desert. However, the topography of Dubai is significantly different from that of the southern portion of the UAE in that much of Dubai's landscape is highlighted by sandy desert patterns, while gravel deserts dominate much of the southern region of the country. The sand consists mostly of crushed shell and coral and is fine, clean and white. East of the city, the salt-crusted coastal plains, known as sabkha, give way to a north-south running line of dunes. Farther east, the dunes grow larger and are tinged red with iron oxide.
The flat sandy desert gives way to the Western Hajar Mountains, which run alongside Dubai's border with Oman at Hatta. The Western Hajar chain has an arid, jagged and shattered landscape, whose mountains rise to about 1,300 meters in some places. Dubai has no natural river bodies or oases; however, Dubai does have a natural inlet, Dubai Creek, which has been dredged to make it deep enough for large vessels to pass through. Dubai also has multiple gorges and waterholes which dot the base of the Western Al Hajar mountains. A vast sea of sand dunes covers much of southern Dubai, and eventually leads into the desert known as The Empty Quarter. Seismically, Dubai is in a very stable zone—the nearest seismic fault line, the Zagros Fault, is 200 km (124.27 mi) from the UAE and is unlikely to have any seismic impact on Dubai. Experts also predict that the possibility of a tsunami in the region is minimal because the Persian Gulf waters are not deep enough to trigger a tsunami.
