The Grand Challenges Exercise…

Seven grand challenges in computing for the next twenty years are outlined by the British Computer Society.

- In Vivo-in Silico (iViS): the virtual worm, weed and bug;
- Science for global ubiquitous computing;
- Memories for life: managing information over a human lifetime;
- Scalable ubiquitous computing systems;
- The architecture of brain and mind;
- Dependable systems evolution;
- Journeys in non-classical computation.

Plate Tectonics of the 2004 Sumatra-Andaman Earthquake & Tsunami

The epicenter occured where the Indian Plate and the South-East Asian Plate are converging off the coast of Sumatra.

Elasticity of tectonic plates and their tendancy to want to return to an original shape dictated by the crystalline lattice structure of basalt minerals is the reason why earthquakes occur. As two plate boundaries press against each other, friction causes each to hold on to each other until they slip. The elastic nature of each plate springs it back to a state of equilibrium and in that millisecond of action, meters of distance are returned, and the shockwave can be heard all over the world. Geological Survey of India

Tsunami Early Warning Systems for the Indian Ocean

Early warning systems for earthquakes and tsunamis in the Indian Ocean will be coming online soon and then the world will be a little safer. The technologies used for these warning systems will include pressure recording systems laid on the ocean floor and linked to surface data buoys to regional emergency management agencies and then broadcast over an Emergency Broadcasting System. Development of all of this will unify many nations as they make improvements to the communications infrastructure and create a truly robust and effective system.

Makers of ocean observation systems include Sound Ocean Systems and National Oceanic and Atmospheric Administration.

Sources for emergency broadcasting systems include Information Station Specialists and US Federal Communications Commission.
