The Seven Wonders of the World (or the Seven Wonders of the Ancient World) refers to remarkable constructions of classical antiquity listed by various authors in guidebooks popular among the ancient Hellenic tourists, particularly in the 1st and 2nd centuries BC. The most prominent of these, the versions by Antipater of Sidon and an observer identified as Philo of Byzantium, comprise seven works located around the eastern Mediterranean rim. The original list inspired innumerable versions through the ages, often listing seven entries. Of the original Seven Wonders, only one—the Great Pyramid of Giza, the oldest of the ancient wonders—remains relatively intact.

In the twentieth century, earthquakes have killed hundreds of thousands of people and caused billions of dollars in damage. Seismologists predict the worst is yet to come.

With the help of astonishing footage and interviews, the show reveals the shocking and frightening secrets of this natural killer. You'll discover why New Yorkers and Bostonians should fear earthquakes just as much as Californians, why Tokyo could literally burn to the ground at any time, why Los Angeles could experience another major quake soon, and what will happen if the "Big One" hits.

Al Qaeda Plane Hijack - Documentary Film About Al Qaeda Plane Hijacking.

Al-Qaeda, translation: "The Base" and conversely meant al-Qaida and often al-Qa'ida) is a global militant Islamist organization started by Osama bin Laden, Abdullah Azzam, and several various other militants, at some point between August 1988 and late 1989, with sources traceable to the Soviet war in Afghanistan. During the Syrian civil war, al-Qaeda factions began battling each various other, as well as the Kurds and the Syrian government.

Al-Qaeda has actually positioned assaults on military and private targets in numerous countries, consisting of the September 11 attacks, the 1998 United States embassy battles and the 2002 Bali battles. The United States government reacted to the September 11 strikes by releasing the "War on Terror". With the loss of crucial leaders, winding up in the death of Osama container Laden, al-Qaeda's procedures have devolved from activities that were regulated from the leading down, to actions by franchise business connected teams and lone-wolf drivers.

The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.It has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes. It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt.
About 90% of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire. The next most seismic region (5--6% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt, which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic Ridge is the third most prominent earthquake belt.
The Ring of Fire is a direct result of plate tectonics and the movement and collisions of lithospheric plates. The eastern section of the ring is the result of the Nazca Plate and the Cocos Plate being subducted beneath the westward moving South American Plate. The Cocos Plate is being subducted beneath the Caribbean Plate, in Central America. A portion of the Pacific Plate along with the small Juan de Fuca Plate are being subducted beneath the North American Plate. Along the northern portion, the northwestward-moving Pacific plate is being subducted beneath the Aleutian Islands arc. Farther west, the Pacific plate is being subducted along the Kamchatka Peninsula arcs on south past Japan. The southern portion is more complex, with a number of smaller tectonic plates in collision with the Pacific plate from the Mariana Islands, the Philippines, Bougainville, Tonga, and New Zealand; this portion excludes Australia, since it lies in the center of its tectonic plate. Indonesia lies between the Ring of Fire along the northeastern islands adjacent to and including New Guinea and the Alpide belt along the south and west from Sumatra, Java, Bali, Flores, and Timor. The famous and very active San Andreas Fault zone of California is a transform fault which offsets a portion of the East Pacific Rise under southwestern United States and Mexico. The motion of the fault generates numerous small earthquakes, at multiple times a day, most of which are too small to be felt. The active Queen Charlotte Fault on the west coast of the Haida Gwaii, British Columbia, Canada, has generated three large earthquakes during the 20th century: a magnitude 7 event in 1929; a magnitude 8.1 in 1949 (Canada's largest recorded earthquake); and a magnitude 7.4 in 1970.

The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres (1,580 mi) long but has an average width of only 69 kilometres (43 mi). It reaches a maximum-known depth of 10,994 m (± 40 m) or 6.831 mi (36,070 ± 131 ft) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end, although some unrepeated measurements place the deepest portion at 11.03 kilometres (6.85 mi).

At the bottom of the trench the water column above exerts a pressure of 1,086 bars (15,750 psi), over 1000 times the standard atmospheric pressure at sea level. At this pressure the density of water is increased by 4.96%, making 95 litres of water under the pressure of the Challenger Deep contain the same mass as 100 litres at the surface. The temperature at the bottom is 1 to 4 °C.

The trench is not the part of the seafloor closest to the center of the Earth. This is because the Earth is not a perfect sphere: its radius is about 25 kilometres (16 mi) less at the poles than at the equator. As a result, parts of the Arctic Ocean seabed are at least 13 kilometres (8.1 mi) closer to the Earth's center than the Challenger Deep seafloor.

Xenophyophores have been found in the trench by Scripps Institution of Oceanography researchers at a record depth of 10.6 km (6.6 mi) below the sea surface. On 17 March 2013, researchers reported data that suggested microbial life forms thrive within the trench.
