2. Tsunami Mitigation Plan for Manakarra Beach of West Sulawesi Province, Indonesia Achmad Yasir Baedaa, Dadang Ahmad Suriamihardjab, Hasdinar Umara, Taufiqur Rachmana* aOcean Engineering, Hasanuddin University, Tamalanrea, 90245, INDONESIA bPhysics, Hasanuddin University, Tamalanrea, 90245, INDONESIA Abstract Due to the increasing activities of underwater earthquake … Most waves are generated by strong winds blowing across vast stretches of the ocean. Tsunamis are giant walls of water. In order for a volcano to produce a tsunami you need: 1. 2001. To make less rigorous or penal. As for the study site, the damaged area by the 2011 Japanese tsunami around the Torinoumi Lagoon located on the south side of the Abukumagawa River mouth in Miyagi Prefecture was selected. This requires cooperation in sea level and seismic networks and data sharing, standardization and understanding of tsunami threat criteria, and effective dissemination of useful tsunami information. Definition: Mitigation means reducing risk of loss from the occurrence of any undesirable event.This is an important element for any insurance business so as to avoid unnecessary losses. 2. One of the best known examples of investment in disaster mitigation is the Red River Floodway. 2. The water then recedes, and more waves follow at intervals of 10-20 minutes. The following material is excerpted from Tsunami! 2. Landslides that enter fjords or lakes can cause tsunamis, which endanger people and infrastructure far from the landslide itself. Mitigation activities are critical for preparing local governments and community populations for the potential of tsunami impact. This makes a tsunami wave far more powerful and dangerous than surfing waves. They speed along as fast as jet planes. In Hawaiʻi, tsunamis have killed more people in the last hundred years than earthquakes, volcanoes, hurricanes, brushfires, and floods combined. Greenbelt tsunami prevention in South Pacific region. For these earthquakes, there is a warning time of a few hours. Disaster mitigation measures are those that eliminate or reduce the impacts and risks of hazards through proactive measures taken before an emergency or disaster occurs. Causes of the Tsunami. Defining the Hazard: The City of Newport’s risk to a tsunami is approximately 100 times higher than the risk to a tornado anywhere in the United States. They are caused by hurricanes, heavy rainfall, overflowing rivers, broken dams, overfilled urban drainage basins, tsunamis, water channels with steep sides, and ice- or snow-melt. Therefore, in the pre-earthquake phase, preparedness, mitigation and prevention are concepts to work on. Comprehensive tsunami mitigation programs require complementary and … MITIGATION. Tsunamis are sometimes incorrectlycalled "tidal waves" -- tsunamis are not causedby the tides (tides are caused by thegravitational force of the moon on the sea).Regular waves are caused by the wind.•If the first part of a tsunami to reach land is atrough—called a drawback—rather than awave crest, the water along the shorelinerecedes dramatically, exposing normallysubmerged areas. One of the best known examples of investment in disaster mitigation is the Red River Floodway. Ongoing and sustained action to reduce the probability of, or lessen the impact of, an adverse incident. Therefore, this study aims to clarify the tsunami mitigation effect of a lagoon on the surrounding area. Instead the water is forced to stack up in height and rush far inland at tremendous speed. The UNESCO IOC Tsunami Glossary includes the definition of tsunami-related technical terms, and information on the global intergovernmental coordination groups for tsunami warning and mitigation. Source(s): India - government . Therefore, this study aims to clarify the tsunami mitigation effect of a lagoon on the surrounding area. The tsunami was generated by a large earthquake in the Southern Pacific Ocean. The source of the plant is known that 90% of the tsunami is caused by tectonic earthquake activity, 9% due to volcanic activity and 1% by soil landslides that occurring in water such as in the lakes or in the ocean or landslides that came from land which is enters to the ocean. Tsunami victims suffer psychology problems in the days and weeks after the destruction. They can be similar to a tide cycle occurring in just 10 to 60 minutes instead of 12 hours. Tsunami Event Data A coordinated U.S. national effort to mitigate the impact of tsunamis through public education, community response planning, hazard assessment, and warning coordination.
