I'm fine
Hey all. Just connecting from my cell phone. So will be brief. Well i am fine not in london today. Although if like normal i took my birthday off work, id have been there today. About 12 i was pulled out of a meeting to be told but it was not until 4 for hearing from family in town. I heard from my mom about 7 and felt much better. Friends all seem to be accounted for too :) i am still planning to head in tomorrow evening unless my friend cancels. Friends were near the bus bomb and heard it in off. Which is concerning, but even if i knew something was going to happen in london, id still go in as normal. I wonder why the places selected were chosen. They seem odd and ill understood. I hope that the death toll does not go up any more. I also hope they catch the little shits. I wish all you readers are well and have your family with you tonight. X

Tsunami
A few little things about Tsunami
1. The Tsunami that hit recently was caused by a subduction earthquake due to natural plate tectonics. The earthquake was not predictable with any accuracy at all! Similarly the Tsunami was also not predictable. Oil and gas activities as well as global warming had no effects. I can see why someone started these rumours on the internet. as the film the day after tomorrow showed a Tsunami and oil and gas exploration use seismic sensors which are in use in the Indian ocean. But these are totally erroneous and to be forgotten.
2. A Tsunami is a very different wave from those normally in the sea. I think that a good analogy is a pond with some wind generated ripples on the surface. They generally go in one direction at the same speed and with the same height etc. But if you throw a pebble in to the pond the ripples this create can be larger or smaller than the other ripples (depending on the size of the pebble) which can move at a speed independent of the other ripples. The new ripples also move out from the drop point in all directions. this is the same as a tsunami apart from instead of a pebble. The water surface was distorted by water pressure change in the ocean above a subduction zone.
3. The Tsunami wave contained far more energy than the normal Indian Ocean wave. But wave energy does not mean more wave height. instead they lead to a wave which has greater influence below the surface and penetrates deeper than the surrounding waves. They move faster than expected (I understand the recent Tsunami moved at nearing 500mph). in the ocean these waves are hard to spot especially with insitu wave sensors. As they come close to shore the deepest part of a wave influence would hit the seafloor and start to be pushed up making the wave height increase also. as with a normal wave. at a certain point on a beach the wave crashes and a face of wave rushes ashore in a bubble of turbulence. A tsunami will do this sooner than a normal wave with a huge amount of energy to continue moving across the land rather than just up a beach.
I'll try and get some links and images up later. But I am waiting till I can see if we have any data for that part of the world which may include it. If you have any questions let me know :^)
Here is a good link
