The global positioning system (GPS) is in the process of providing faster Tsunami alerts, which the long sea wave caused by an earthquakenews24 . This was done by the German researcher, citing data collected after the last year’s deadly Japan earthquake which is a sudden violent shaking of the ground. On the occasion of the Fukushima earthquake the analyzed data from more than 500 GPS stations showed that a correct estimate of the magnitude of 9.0 generated Tsunami could have been possible in just three or four minutes after the earthquake. This shows us what kind of potential a GPS shield has on the Tsunami’s early warning systems, not forgetting that this also proves how much technology keeps improving on a daily basis. These are the findings that are presented lately. If an earthquake occurs near the coast, it can take just 20-30 minutes before it hits the land, but GPS measurements taken almost while the earthquake is in progress, would enable a faster assessment of its scale. The GPS’s traditional methods require more time to provide an accurate picture, often underestimating the magnitude of a quake at first. In the case of last year’s earthquake which happened at Japan, the authorities became aware of its scale only 20 minutes after the event. Possibly leading to many more casualties than if a warning had gone out earlier. This just proves to us that here in South-Africa we should be grateful we do not have any natural disasters. About 19000 people died when a 9.0 magnitude earthquake took off the northeastern coast of Japan on 11 March 2012. This is one of the useful gadgets that we could consider as it saves lives so that the people can be able to know when to take measures when Tsunami is about to occur.
