tsunami


Tsunami by Hokusai 19th Century
A tsunami (Japanese: "harbor wave"; English pronunciation: / tsoo-NAH-mee) is a series of water waves (also called a tsunami wave train) caused by the displacement of a large volume of a body of water, usually an ocean, though it can occur in large lakes. Tsunamis are a frequent occurrence in Japan; approximately 195 events have been recorded. Owing to the immense volumes of water and the high energy involved, tsunamis can devastate coastal regions.

Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides and other mass movements, meteorite ocean impacts or similar impact events, and other disturbances above or below water all have the potential to generate a tsunami.

The Greek historian Thucydides was the first to relate tsunami to submarine earthquakes, but the understanding of a tsunami's nature remained slim until the 20th century and is the subject of ongoing research. Many early geological, geographical, and oceanographic texts refer to tsunamis as "seismic sea waves." (read more)

roger, go with throttle up...


The Space Shuttle Challenger disaster occurred on Tuesday, January 28, 1986, when Space Shuttle Challenger broke apart 73 seconds into its flight, leading to the deaths of its seven crew members. The spacecraft disintegrated over the Atlantic Ocean, off the coast of central Florida, United States, at 11:38 a.m. EST (16:38 UTC).


Disintegration of the entire vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized hot gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB attachment hardware and external fuel tank. This led to the separation of the right-hand SRB's aft attachment and the structural failure of the external tank. Aerodynamic forces promptly broke up the orbiter.


The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. Although the exact timing of the death of the crew is unknown, several crew members are known to have survived the initial breakup of the spacecraft. However, the shuttle had no escape system and the astronauts did not survive the impact of the crew compartment with the ocean surface.


The disaster resulted in a 32-month hiatus in the shuttle program and the formation of the Rogers Commission, a special commission appointed by United States President Ronald Reagan to investigate the accident. The Rogers Commission found that NASA's organizational culture and decision-making processes had been a key contributing factor to the accident. NASA managers had known that contractor Morton Thiokol's design of the SRBs contained a potentially catastrophic flaw in the O-rings since 1977, but they failed to address it properly. They also disregarded warnings from engineers about the dangers of launching posed by the low temperatures of that morning and had failed to adequately report these technical concerns to their superiors. The Rogers Commission offered NASA nine recommendations that were to be implemented before shuttle flights resumed. (read more)

December 7, 1941


USS Arizona (BB-39) was a Pennsylvania-class battleship of the United States Navy and the first to be named "Arizona". On March 4, 1913, Congress authorized the construction of Arizona, named to honor the 48th state's admission into the union on 14 February 1912. The ship was the second and last of the Pennsylvania class of "super-dreadnought" battleships.

She is most remembered because of her sinking, with the loss of 1,177 lives, during the Japanese attack on Pearl Harbor on 7 December 1941, the event that goaded the US into World War II. Unlike most of the other ships sunk or damaged that day, the Arizona could not be salvaged, although the U.S. Navy removed several elements of the ship that were reused. The wreck still lies at the bottom of Pearl Harbor and was established as a memorial to all those who died during the Pearl Harbor attack. (read more)

Camp Hope

"hip hip hooray"

Chilean rescuers moving at a rapid pace pressed ahead with the operation to free 33 men trapped half a mile below the earth's surface for more than two months.

Rescuers freed the 27th miner as family members and hundreds of international media held vigil. The pace of the rescues quickened throughout the day, with some men rising to safety within 30 minutes of each other.

The 26th miner rescued, Claudio Acuña, 34, has worked in mining about 10 years. According to CNN, he's married, has a daughter and is the youngest of eight brothers.

"We have lived a magical night, a night we will remember throughout our lives, a night in which life defeated death," declared Chilean President Sebastian Piñera, who welcomed the miners as they emerged from the rescue pod one at a time. (latimes)

How Three Firms Came To Rule The World


"One often hears the statement that agriculture is changing and we must adapt to the changes", says William Heffernan, a professor of rural sociology at the University of Missouri. "Few persons who repeat the statement really understand the magnitude of the changes and the implications of them for agriculture and for the long-term sustainability of the food system. It is almost heresy to ask if these changes are what the people of our country really want or, if they are not what is desired, how we might redirect the change. These changes are the result of notoriously short-sighted market forces and not the result of public dialogue, the foundation of a democracy. Neither are the changes the result of some mystical figure or an 'invisible hand'."

Earlier this year the Farmers' Union hired Heffernan to undertake a study on consolidation in agricultural trade. Heffernan concluded that once you disentangle a web of subsidiaries, mergers, joint ventures, parternships, side agreements, marketing arrangements and alliances you find that "three food chains dominate the global food production system". These chains are: Cargill/Monsanto; ConAgra and Novartis/ADM. Even so, Heffernan notes that because of lax reporting requirements it's difficult to get a fix on precisely what these companies own and how they go about doing business. "Cargill has operations in 70 countries and it's a privately held firm. How do we get all of the necessary information? We've exposed the tip of the iceberg, but exposure only indicates the type of information needed to understand the global food system."

Heffernan points to the Cargill/Monsanto cluster as one of the most dangerous of the new alliances. In 1998 Monsanto and Cargill announced that Cargill had sold its vast seed operation to Monsanto (the world's leading biotech outfit) and entered into an agreement with the chemical company to develop new kinds of crop biotechnology. This alliance presents distinct benefits to both companies but dangers to consumers, farmers and the environment. A case in point is the alliances' so-called terminator gene. "No longer will Monsanto have to depend on access to farmers' fields for collection of tissue samples to make sure farmers do not keep seed from one year's crop to plant the following year", Heffernan warns. "Use of the terminator gene will mean that all crop farmers must return each year to obtain their seed from seed firms, just as corn producers have had to do for the past half-century."

If the press, which rarely mentions agricultural issues anymore, doesn't take this turn of events seriously, the corporate leaders of the agri-conglomerates certainly do. And they are not the least bit bashful about what's at stake. Dwayne Andreas is the politically wired former CEO of Archer Daniels Midland. He recently boasted to Reuters that he wanted to make ADM the world's dominant agriculture firm because, to his way of thinking, there's simply nothing more powerful than controlling the world's food supply. He said agribusiness is more powerful than the oil industry.

"The food business is far and away the most important business in the world," Andreas said. "Everything else is a luxury. Food is what you need to sustain life every day. Food is fuel. You can't run a tractor without fuel and you can't run a human being without it either. Food is the absolute beginning." (read more)
