Discovery channel asia.malam ini pk 9 (HK time) atau 8 malam WIB . RDP === Unstoppable Wave In an unprecedented effort to capture the impact of an underwater earthquake and in an attempt to understand what really caused the devastating 2004 Asian Tsunami, a crew of producers and internationally-renowned scientists - including Canadians David Mosher, the geophysicist in charge of seismic survey; and Kate Moran, lead oceanographer and co-director of the expedition - sent cameras deep into the abyss to analyze and photograph the evidence for the first time. Their goal was to develop an accurate warning system for when and where the next tsunami may hit. Among their significant discoveries: new geological evidence suggests that it was the seafloor uplift from the 9.1 magnitude Great Sumatra earthquake - and not a giant underwater landslide as previously thought - that caused the devastating 2004 tsunami. This special chronicles a voyage of remarkable scientific discovery, 260 kilometres off the coast of Banda Aceh, Indonesia, as 24 geologists, geophysicists, oceanographers, biologists, computer modellers and tsunami experts - with the aid of seismic survey equipment and remotely operated underwater vehicles (ROVs) - the team collects the data required to not only understand last year's tsunami, but to develop a computer model that could be used to predict the size of future tsunamis elsewhere in the world, and ultimately, help save thousands of lives. Almost five kilometres below the ocean surface, one ROV reveals evidence that the sea floor was pushed upwards during the earthquake. The size of the uplift far exceeds anything scientists had predicted - in some places the displacement measures over 12 metres. Scientists now confirm that this uplift caused the deadly tsunami - 1,200 kilometres of the fault line ruptured in just 500 seconds, causing a drastic uplift, raising the ocean waters above, and triggering the deadly wave. The expedition scientists have created a computer model capable of calculating the height and speed of future tsunamis, a powerful tool that will enable governments to improve natural coastal protection systems, plan for levels of destruction and prepare evacuation measures. Researchers have studied global fault lines and identified the south coastline of Sumatra and the northwest United States as the next most likely areas for a future tsunami strike. Sumatran authorities have identified areas that will be above the wave height and now conduct regular emergency evacuation exercises; authorities in Oregon and Washington have implemented early warning systems, identified evacuation routes and safe areas. It's a start, but the expedition's computer model shows that these plans are hopelessly inadequate - a 9.1 Richter scale earthquake would create a tsunami double the height for which the region was prepared and would affect over 500,000 people in just 15 minutes. -- --Writer need 10 steps faster than readeR -- --------------------------------------------------------------------- To unsubscribe, send email to: iagi-net-unsubscribe[at]iagi.or.id To subscribe, send email to: iagi-net-subscribe[at]iagi.or.id Visit IAGI Website: http://iagi.or.id IAGI-net Archive 1: http://www.mail-archive.com/iagi-net%40iagi.or.id/ IAGI-net Archive 2: http://groups.yahoo.com/group/iagi Komisi Sedimentologi (FOSI) : Ratna Asharina (Ratna.Asharina[at]santos.com)-http://fosi.iagi.or.id Komisi SDM/Pendidikan : Edy Sunardi(sunardi[at]melsa.net.id) Komisi Karst : Hanang Samodra(hanang[at]grdc.dpe.go.id) Komisi Sertifikasi : M.
