Main topic of this report will support RTerg than forecast volcanic eruptions in terms of technological advanced level and frequency of each natural disaster. Therefore, at the conclusion section, RTerg will be state as one of the greatest scientific inventions and it will prevent the people from tsunami. 1.0 Introduction The purpose of this report is research to compare and contrast two recent scientific advances. The two scientific advances that choose are “New system can warn of tsunami within minutes” and “Oscillating ‘plug’ of magma causes tremors that forecast volcanic eruptions”. Because of too many casualties from tsunami, seismologists have developed RTerg, which is warm tsunami only minutes after the initial earthquake. In addition, geophysicists have developed seismic tremors, which are forecasting explosive volcanic eruptions. Through the research about both scientific advances inventions, RTerg can be more incredible advances better than seismic tremors in terms of level of technology degree. Forecasting a volcanic eruption by seismic tremors is just a method of measurement, but RTerg is highly technological system that warns of tsunami within minutes. 2.0 Methodology For the exact research about this report, using the “E Science News" site to compare and contrast two scientific advances inventions. Because this site contains information about both of RTerg and measure the Oscillating ‘plug’ of magma by seismic tremors. For purpose of gathering more information about RTerg, using websites such as “The Christian Science Monitor” and “Vanuatu Meteorological Services” for reinforce the information about RTerg. In addition, for the purpose of compare and contrast by both scientific advances, investigate more about forecasting methodology of volcanic eruptions in websites such as “Nova Beta”. 19/7/2012 page 1 GAC013 AE#2 Seonguk Cho HUK21740 3.0 Findings The new system which is known by RTerg can helpful to reduce casualties of Tsunami. RTerg was developed by Andrew Newman, who is an assistant professor in the School of Earth and Atmospheric Sciences in 2011. In contrast, oscillating ‘plug’ of magma by seismic tremors is advanced method of predict volcanic eruptions. This system was developed by Mark Jellinek, who is associate professor in the University of British Columbia Department of Earth and Ocean Sciences in 2011. The background of developing RTerg is preparing for the destructive Tsunami earthquake such as the magnitude 7.8 2010 Sumatran earthquake. In addition, by Figure 1 and 2, how tsunami is frequent in every decade and results numerous number of casualties. In contrast, the purpose of developing a new explanation for seismic tremors to forecast volcanic eruption is prevent explosive eruptions such as Mount Pinatubo in Philippines, Chaiten Volcano in Chile, and Mount St. Helens in Washington State. However, by Figure 3 and 4, volcano does not occur frequent than tsunami. Figure 1. Count of all tsunamis for 10-year periods from 1701 to the present.

(Thordarson and Larsen, 2006) 19/7/2012 page 4 GAC013 AE#2 Seonguk Cho HUK21740 4.0 Discussion After examine the findings, RTerg is highly technological scientific advancement than the method of forecasting volcanic eruptions by seismic tremors. Because, when tsunami is occur slowly, RTerg uses algorithmic tools to find out occurrence point only minutes after. In addition, RTerg gets information about the quake’s location, magnitude and depth. The incredible facts about this system is when earthquake in the sea is determined to be of magnitude 6.5 or higher, it send the information to the around 150 seismic stations all over the world in only couple of minutes. However, Oscillating ‘plug’ of magma by tremors is just forecasting volcanic eruptions simply, not a highly technological system. In addition, when RTerg detect earthquake from the sea only couple of minutes, this tremors system preceded volcanic eruptions from hours to weeks. Therefore, there are possibilities that this system contain inaccuracy of forecasting volcanic eruptions. Another reason that this system is far from science advanced technology is simple principle of its working. According to Mark Jellinek, who is an associate professor in the University of British Columbia Department of Earth and Ocean Sciences said that it simply oscillates about the magma rises and forecasting by generating tremors frequencies. Therefore, it can’t be scientific invention compare to the RTerg. In other point of view that RTerg can be more essential scientific advancement for us than forecasting volcanic eruption system by tsunami frequencies and its impacts on casualties. By the figures in the findings, number of the tsunami that occurrence is more than volcanic eruptions. In addition, by Figure 2, numerous people were died by tsunami last 300 years. Through these data, how RTerg is really necessary scientific advancement for our life. Even though, volcanic eruptions are very dangerous natural disaster, but the system that invented by Mark Jellinek is work by just simple principle. Therefore, it can’t be achieved great scientific advancement compare to highly technological invention RTerg. 19/7/2012 page 5 GAC013 AE#2 Seonguk Cho HUK21740 5.0 Conclusions and Recommendations RTerg can be one of the most scientific advanced inventions and it can give significant contribution to prevent tsunami, which is dangerous natural disaster. In the future, tsunami warning system can be more develop and this improvement results people to move safer places quickly. Therefore, people can living feel relief from anxiety about sudden tsunami and also reduce casualties from this dangerous disaster in the future. 19/7/2012 page 6 GAC013 AE#2 Seonguk Cho HUK21740 Appendices Figure 1.
