The GICHD perceives the debate on explosive weapons in populated areas (EWIPA) as a humanitarian issue. Motivated by its strategic goal to improve human security and equipped with subject expertise in explosive hazards, the GICHD established a research project to characterise explosive weapons in January 2015. Our work is made possible by core contributions, project funding and in-kind support from more than 20 governments and organisations. Based at the Maison de la paix in Geneva, the GICHD employs around 55 staff from over 15 countries with unique expertise and knowledge. That resulted in billions of cubic yards of water - trillions of pounds - suddenly shifting position.The Geneva International Centre for Humanitarian Demining (GICHD) is an expert organisation working to reduce the impact of mines, cluster munitions and other explosive hazards in the world, in close partnership with states, the UN and other human security actors. In a rough guess, Harry Yeh, a professor of ocean engineering at Oregon State University, said that the earthquake on Friday pushed a section of sea floor 250 miles long and 50 miles down by an average of one yard. That changes the height of the water above it - what physicists call potential energy - and the potential energy quickly changes into the kinetic energy of the tsunami waves. An earthquake suddenly pushes part of the sea floor up or down. The power of a tsunami comes from straightforward physics. Even if the wave only comes up to the knees, the force is enough to knock a person down. Those added projectiles can create more destruction as they crash into other objects. It also gathers debris - dirt, cars, trees - as it flows. As a fluid, it can slip around some objects like round columns, while slamming full force when a large wall is in its way. Water does not act quite the same way as speeding cars.
