Tsunami is a Japanese term that describes a large seismically generated sea wave which is capable of considerable destruction in certain coastal areas, especially where underwater earthquakes occur.
In Japanese, "Tsunami" means "Harbor Wave" or "Wave In The Harbor" It is now internationally accepted as the term that defines a "Seismic Seawave."
In South America, the term "Maremoto" is frequently used to describe a Tsunami.
Tsunami is pronounced: (sue-NAM-ee)
Tsunami's have been incorrectly referred to as "tidal waves." A tidal wave is a non-technical term for a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth (high water is the crest of a tidal wave and low water is the trough).
Tsunami's are formed by a displacement of water. This can come from the slippage of the boundaries between two tectonic plates, volcanic eruption, under-water earthquake, or even landslides.
Out in the open ocean, Tsunami's might only be 1 meter in height, but as it reaches the shore in shallow water, it can rise to heights of 15-30 meters or more. Think about how a normal wave comes into a shore: the water moves away from the shore and then comes crashing back. This movement "heightens" the destruction power of a Tsunami.
Tsunami's can also reach speeds ranging from 400 to 500+ miles per hour? about the same speed as a jet airliner.
The enormous energy that a Tsunami can possess allows it to travel across entire oceans. They often proceed as an ordinary gravity wave? having a 15 to 60 minute intervals.
From a destruction perspective, Tsunami's have cost not hundreds of thousands, but millions of human lives over the recorded history of Earth.

747 Onboard Laser Might Cause Mistake and Identity
Remember when the Russians shot down a Korean Airlines 747 accidentally, which was 4 degrees off it's course and flew over Russian Airspace. Migs shot it down with two missiles, one hitting the tail and one hitting the left wing, everyone on board died.
Tunneling Concepts for Advanced Warfare
I propose research be done to make unmanned tunneling machines to help in warfare. Today more than ever we see the problems with urban warfare.

Earthquakes, Tsunamis, Mudslides: Extreme Events - What Do They Mean?
In lieu of recent, tumultuous occurrences, people are more compelled than ever to discover the mystery of these modern-day, earth-changing events.One day, Earth(1) is experiencing the fourth largest earthquake in a century - a 9.
Hobbits and Lice
HOBBITS AND LICE:In late 2004 the media was all agog with the small hominids found on Flores Island where I had written about artifacts showing sea travel technology must have existed. I had argued with many people about the issue and their argument had some merit in that we had no proof of a connection to humans or the nearby Mungo Man.
Paternity Testing - Are You Raising Someone Elses Child?
The dawn of the DNA testBack in the 1700s, the best way to determine paternity was by a good hard look and the child, followed by a good hard look at the father. Enough coincidences and maybe a relationship could be proposed.

An Immortal Horse
Egyptian scholars know there is little other than fiction that can be written about the civilization that lived on the banks of the Nile in far more recent times than the beginning of the 'Old Copper Culture'. All these things are related and the old fictions are replaceable with the story of a worldwide culture with trading posts in each and every part of the world.

Acoustic Transducers for High Altitude Balloon Control
Using acoustic transducers it maybe possible to create a small region of thicker air underneath a blimp and use that patch as a platform of air to float on while blowing ever so slightly low pressure air underneath the blimp like a hover craft. Although this idea sounds like a long shot it can be done by use of a screen, which shoots the directed frequency waves into the waves created by the acoustic transducers.

Composite Materials in Ships, Pipelines, Liners and Aircraft
One future problem, which has not sufficiently been addressed, is that of the fumes and smoke created when composite material burns. Composite material is a truly great human achievement in material science, however as we use this material in more and more places we need to be acutely aware of the risks and potential consequences of their use.
Institute of Noetic Sciences
The possibility of sentient beings on earlier solar systems said to be many billions of years older than our own, developing travel and transposition of some teleportational nature seems one of the most stable and down to earth possibilities when we consider these spheres. Other ideas flit through our mind as we imagineer the conscious wisdom of refined metallurgical objects beyond mere silica microchips and revisit what Dr Robins termed the megaliths - macrochips.

The Valuable Individual
How can we, as individuals, participate in waste management? Because some of us are so overwhelmed with Earth's problems, we feel that our contributions have no real consequence in the end. For others, social barriers can be an issue.
Down Scrolling Text to Find Patterns
I believe a program can be written to scan text such as an email, story or article in Western Languages, which might indicate a pattern which maybe of valuable insight. By Down Scrolling Text, which we have all done, whether thinking about it or not, we will most likely Find Patterns Which Indicate Hostile Intentions, sadness, stress or vengefulness.
