Tsunami, a Japanese word meaning "harbor wave", is used as the scientific term for a class of abnormal sea waves that can cause catastrophic damage when it hits a coastline. Tsunamis can be generated by an undersea earthquake, an undersea landslide, the eruption of an undersea volcano, or by the force of an asteroid crashing into the ocean. The most frequent cause of tsunamis is an undersea earthquake.

A tsunami can have wavelengths, or widths (the distance between one wave crest to the next), of 100 to 200 km (60 to 120 mi), and may travel hundreds of kilometers across the deep ocean, reaching speeds of about 725 to 800 km/h (about 450 to 500 mph). A tsunami is not one wave but a series of waves. In the deep ocean, the waves may be only about half a meter (a foot or two) high. People onboard a ship passing over it would not even notice the tsunami. Upon entering shallow coastal waters, however, the waves may suddenly grow rapidly in height. When the waves reach the shore, they may be 15 m (50 ft) high or more. Tsunamis can also take the form of a very fast tide or boring, depending on the shape of the sea floor.

Tsunamis have tremendous force because of the great volume of water affected and the speed at which they travel. Just a cubic yard of water, for example, weighs about one ton. Although the tsunami slows to a speed of about 48 km/h (30 mph) as it approaches a coastline, it has a destructive force equal to millions of tons. Tsunamis are capable of obliterating coastal settlements.

The Blue Whale is the largest whale and the largest living creature on Earth. Blue whales were hunted a lot for oil, baleen, meat, and other products from the 1930s to the 1960s. This hunting almost caused the extinction of the species. They are now protected and may gradually be returning in several areas.

Blue whales are mainly found in very cold waters, like the Arctic and Antarctic waters. They migrate to the tropics in the winter and to the Arctic and Antarctic in the summer. Blue whales can reach over 24 m (80 ft) long; mature females are usually a bit longer than mature males. They weigh between 87,500142,500 kg. The skin has a light grey and white spotty pattern. Blue whales feed by opening its mouth into dense groups of small sea creatures like plankton, krill or fish. Blue whales are mammals. They give birth once every two or three years. Mating occurs during the summer season, and they give birth after about 11 months. The calf nursed for seven or eight months and gain weight of about 90 kg (200 lb) per day.

Streaming video is a sequence of "moving images" that are sent in compressed form over the Internet and displayed by the viewer as they arrive. Streaming media is streaming video with sound. With streaming video or streaming media, a Web user does not have to wait to download a large file before seeing the video or hearing the sound. Instead, the media is sent in a continuous stream and is played as it arrives. The user needs a player, which is a special program that uncompresses and sends video data to the display and audio data to the speakers. A player can be either an integral part of a browser or downloaded from the software maker’s Web site.

Streaming video is usually sent from prerecorded video files, but can be distributed as part of a live broadcast "feed". In a live broadcast, the video signal is converted into a compressed digital signal and transmitted from a special Web server that is able to do multicast, sending the same file to multiple users at the same time.
