 "I'm Yours"

Well, you done done me and you bet I felt it
I tried to be chill but your so hot that i melted
I fell right through the cracks, and i'm tryin to get back
before the cool done run out i'll be givin it my best test
and nothin's gonna stop me but divine intervention
I reckon it's again my turn to win some or learn some

I won't hesitate no more,
no more, it cannot wait i'm yours

Well open up your mind and see like me
open up your plans and damn you're free
look into your heart and you'll find love love love
listen to the music at the moment maybe sing with me
Ah, la peaceful melody
It's your god forsaken right to be loved loved loved loved Loved

So, i won't hesitate no more,
no more, it cannot wait i'm sure
there's no need to complicate our time is short
this is our fate, i'm yours

*scat*

I've been spendin' way too long checkin' my tongue in the mirror
and bendin' over backwards just to try to see it clearer
my breath fogged up the glass
and so I drew a new face and laughed
I guess what I'm a sayin'is there ain't no better reason
to rid yourself of vanity and just go with the seasons
it's what we aim to do
our name is our virtue

I won't hesitate no more, no more
it cannot wait, i'm sure
(there's no need to complicate
our time is short
it cannot wait, i'm yours 2x

no please don't complicate, our time is short
this is our fate, im yours.
no please don't hesitate no more, no more
it cannot wait, the sky is yours!)

well open up your mind and see like me
open up your plans and damn you're free
look into your heart and you'll find love love love love
listen to the music of the moment come and dance with me
ah, la one big family
it's your god forsaken right to be loved, loved, loved, loved
open up your mind and see like me
open up your plans and damn you're free
look into your heart and you'll find love love love love
listen to the music of the moment come and dance with me
ah, la happy family
it's our god forsaken right to be loved loved loved loved
listen to the music of the moment come and dance with me
ah, la peaceful melodies
it's you god forsaken right to be loved loved loved loved...

Tsunami

A tsunami (pronounced /tsuːˈnɑːmi/) is a series of wave created when a body of water, such as an ocean, is rapidly displaced. Earthquakes, mass movements above or below water, some volcanic eruptions and other underwater explosions, landslides, underwater earthquakes, large asteroid impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami. The effects of a tsunami are always devastating due to the immense volumes of water and energy involved. Since meteorites are small, they will not generate a tsunami.
The term tsunami comes from the Japanese meaning literally (tsu)harbor (nami)wave.
The Greek historian Thucydides was the first to relate tsunamis to submarine quakes, but understanding of the nature of tsunamis remained slim until the 20th century and is the subject of ongoing research.
Many early geological, geographic, oceanographic etc; texts refer to "Seismic sea waves" - these are now referred to as "tsunami."

Warnings and prevention

Geologists, Oceanographers and Seismologist analyse each earthquake and based upon many factors may or may not issue a tsunami warning. However, there are some warning signs of an impending tsunami, and there are many systems being developed and in use to reduce the damage from tsunami. One of the most important systems that is used and constantly monitored are bottom pressure sensors. These are anchored and attached to buoys. Sensors on the equipment constantly monitor the pressure of the overlying water column - this can be deduced by the simple calculation of:
F = Gdh
where F = the overlying force or pressure in Newtons per metre square, G is the acceleration due to gravity, d = the density of the water and h = the height of the water column.
G = 9.8 m s2, d = 1.1 x 103 kg m3 and h is the depth of water in metres
Hence for a water column of 5,000 m depth the overlying pressure is equal to 9.8 x 1.1 x 103 x 5 x 103 or about 5.4 x 10 7 N m2 or about 5.7 Million tonnes per metre square.
In instances where the leading edge of the tsunami wave is the trough, the sea will recede from the coast half of the wave's period before the wave's arrival. If the slope of the coastal seabed is shallow, this recession can exceed many hundreds of meters. People unaware of the danger may remain at or near the shore out of curiosity, or for collecting fish from the exposed seabed. During the Indian Ocean tsunami of 26th December 2004, the sea withdrew and many people then went onto the exposed sea bed to investigate. Pictures taken show people on the normally submerged areas with the advancing wave in the background. Most people who were on the beach were unable to escape to high ground and died.Regions with a high risk of tsunami may use tsunami warning systems to detect tsunami and warn the general population before the wave reaches land. On the west coast of the United States, which is prone to Pacific Ocean tsunami, warning signs advise people of evacuation routes.
The Pacific Tsunami Warning System is based in Honolulu. It monitors all sesimic activity that occurs anywhere within the Pacific. Based up the magnitude and other information a tsunami warning may be issued. It is important to note that the subduction zones around the Pacific are seismically active, but not all earthquakes generate tsunami and for this reason computers are used as a tool to assist in analysing the risk of tsunami generation of each and every earthquake that occurs in the Pacific Ocean and the adjoining land masses.
As a direct result of the Indian Ocean tsunami, a re-appraisal of the tsunami threat of all coastal areas is being undertaken by national governments and the United Nations Disaster Mitigation Committee. A tsunami warning system is currently being installed in the Indian Ocean.
Computer models can predict tsunami arrival - observations have shown that predicted arrival times are usually within minutes of the predicted time. Bottom pressure sensors are able to relay information in real time and based upon the readings and other information about the seismic event that triggered it and the shape of the seafloor (bathymetry) and coastal land (topography), it is possible to estimate the amplitude and therefore the surge height, of the approaching tsunami. All the countries that border the Pacific Ocean collaborate in the Tsunami Warning System and most regularly practice evacuation and other procedures to prepare people for the inevitable tsunami. In Japan such preparation is a mandatory requirement of government, local authorities, emergency services and the population.
Some zoologists hypothesise that animals may have an ability to sense subsonic Rayleigh waves from an earthquake or a tsunami. Some animals seem to have the ability to detect natural phenomena and if correct, careful observation and monitoring could possibly provide advance warning of earthquakes, tsunami etc. However, the evidence is controversial and has not been proven scientifically. There are some unsubstantiated claims that animals before the Lisbon quake were restless and moved away from low lying areas to higher ground. Yet many other animals in the same areas drowned. The phenomenon was also noted in Sri Lanka in the 2004 Indian Ocean earthquake. The following two references whilst revelant, are media and not scientific - (BBC, (Kenneally,). It is possible that certain animals (e.g., elephants) may have heard the sounds of the tsunami as it approached the coast. The elephants reaction was to move away from the approaching noise - inland. Some humans, on the other hand, went to the shore to investigate and many drowned as a result.
It is not possible to prevent a tsunami. However, in some tsunami-prone countries some measures have been taken to reduce the damage caused on shore. Japan has implemented an extensive programme of building tsunami walls of up to 4.5 m (13.5 ft) high in front of populated coastal areas. Other localities have built floodgates and channels to redirect the water from incoming tsunami. However, their effectiveness has been questioned, as tsunami often surge higher than the barriers. For instance, the Okushiri, Hokkaidō tsunami which struck Okushiiri Islan of Hokkaidō within two to five minutes of the earthquake on July 12, 1993 created waves as much as 30 m (100 ft) tall - as high as a 10-story building. The port town of Aonae was completely surrounded by a tsunami wall, but the waves washed right over the wall and destroyed all the wood-framed structures in the area. The wall may have succeeded in slowing down and moderating the height of the tsunami, but it did not prevent major destruction and loss of life. (This reference is Japanese -)
The effects of a tsunami may be mitigated by natural factors such as tree cover on the shoreline. Some locations in the path of the 2004 Indian Ocean tsunami escaped almost unscathed as a result of the tsunami's energy being absorbed by trees such as coconut palms and mangroves. In one striking example, the village of Naluvedapathy in India's Tamil Nadu region suffered minimal damage and few deaths as the wave broke up on a forest of 80,244 trees planted along the shoreline in 2002 in a bid to enter the Guinness Book of Records. Environmentalists have suggested tree planting along stretches of seacoast which are prone to tsunami risks. It would take some years for the trees to grow to a useful size, but such plantations could offer a much cheaper and longer-lasting means of tsunami mitigation than the construction of artificial barriers.
