Tsunami Mitigation

The coastal areas are vulnerable areas to disaster threats, especially the geological hazards of earthquakes accompanied by tsunamis. Palu City, which is located on the west coast of Sulawesi, experienced a natural disaster of an earthquake, tsunami, and liquefaction on September 28, 2018. Based on the Map of Disaster Prone Index in Central Sulawesi Province, Palu City is a tsunami-prone area that is crossed by the Palu-Koro Fault. Tsunami disaster mitigation efforts in coastal areas can be done by planting mangrove ecosystems as a green barrier. The purpose of this study is to analyze the characteristics of the coastal landscape in Palu City and plan the landscape of tsunami mitigation based on mangrove ecosystems in Palu City. The method used spatial analysis method and descriptive method, as well as the research stage, consists of preparation, data analysis, data synthesis, and landscape planning stage. The basic concept of tsunami mitigation landscape planning is to reduce or eliminate disaster risk in coastal areas based on mangrove ecosystems. The concept of spatial pattern concept consists of high hazard zones, medium hazard zones, and low hazard zones. The concept of vegetation refers to the diversity of mangrove and native plant species as green open spaces and green barriers.

Tsunami Disaster

Indonesia coastal areas have considerable natural disaster potential including in Kalianda District South Lampung Regency. Natural disasters such as earthquakes, tsunamis and volcanic activity are likely to occur in coastal areas. The disaster has an impact on economic losses in the marine tourism area. In order to mitigate tsunami disasters in the marine tourism area of Kalianda District, South Lampung Regency, 3 (three) types of tsunami mitigation are needed, namely: construction of coastal protection, installation of the Tsunami Early Warning System (TEWS) and planting of coastal vegetation. This study aims to determine the value of willingness to pay (WTP) of community and tourists in supporting the management of the three types of tsunami disaster mitigation above by using economic valuation / Contingent Valuation Method (CVM). The results of this study indicate that the WTP value of community for coastal protection management is Rp 15.547/person/month while the WTP value of tourist is Rp 12.030/one time entry. Meanwhile, for the WTP value of TEWS management is obtained Rp 12.174/person/month. WTP value for the management of coastal vegetation is Rp 12.444/person/month. The WTP calculation is based on consideration of 3 (three) factors, namely age, income, livelyhood and education level. This research shows that the community and tourists are willing to pay for the management of the three types of tsunami disaster mitigation through BUMDes and entrance fees for marine tourism area. The three types of tsunami disaster mitigation can protect, provide security and calm to the community and tourists in the marine tourism area of Kalianda District, South Lampung Regency from future tsunami.

ABSTRACT Coastal Landscape Planning in Pangandaran Based on Tsunami Disaster Mitigation The Indonesian archipelago has a long coastline of about 81,000 km. Some coastal areas in Indonesia, classified in areas with high risk of tsunami. The objective of this research was to develop a coastal planning in Pangandaran and provide recommendations related to tsunami disaster mitigation. The tsunami ever occurred at the site studied, namely in 2006. The method used in this study is a modification of the method of planning (Gold 1980) which comprise the step of preparation, inventory, analysis, synthesis, and planning. Analysis is conducted analysis of regional vulnerability to tsunamis. The results from the analysis found that Pangandaran beach is classified as an area highly vulnerable to tsunami, based on an assessment of the slope, elevation, land use, distance from the river and distance from the coast. Analysis of the suitability of the area for evacuation was conducted to determine the exact area used as a tsunami evacuation. The concept of planning is divided into space concept, the concept of activity, the concept of infrastructure, circulation concept and the concept of vegetation. The concept that there is then developed to produce a landscape plan, plan activities, circulation plan, vegetation plans, and plan infrastructure facilities.

This paper describes tsunami disaster mitigation in the West Sumatra region with participatory technology assessment (pTA), which promotes direct interaction among member and experts to discuss issues and reach consensus for mitigation through provision of information and knowledge of science and technology. Two areas were examined: Padang, the capital city; and Painan city, a town in southern West Sumatra Province, Indonesia. Tsunami have damaged these areas at least three times: in 1797, a 5–10-m-high tsunami wave height hit the area; in 1833, a 3–4-m-high tsunami came; and in 2007, an 8.4 Mw earthquake generated a local tsunami with maximum wave height of 1.5 m, as observed near Painan. Because of the high level of tsunami risk resulting from its flat topographic conditions, their respective populations of 820,000 people and 15,000 people are developing tsunami mitigation efforts with support of national institutions and international experts. These cities had different starting points and approaches. Efforts were introduced to produce official tsunami hazards maps. Insights from these lessons and ideas arising from the ongoing process after the 2007 South Sumatra and 2009 Padang earthquakes are discussed herein.

Purpose – The purpose of this paper is to assess the vulnerability of the Kesennuma area in Japan to a tsunami disaster and to map the area of inundation. Design/methodology/approach – Digital elevation model (DEM) data and ALOS image were used to create maps of the parameters of this study area: elevation, slope, coastal proximity, river, and land use. An analytical hierarchy process was used to assign weights to each parameter and a spatial multi-criteria analysis was applied through cell-based modelling for vulnerability mapping. Findings – The vulnerability map shows that 17.679 km2 of the area could be inundated by a tsunami. High vulnerability areas were mostly found in coastal areas with a sloping coast and a cape area. A low elevation and the presence of rivers or water channels are factors that increase the impact of tsunamis. Inundation areas were predicted to spread in areas identified as having either high vulnerability or slightly high vulnerability. Research limitations/implications – Because of the limited geospatial data, the authors encourage further studies using DEM data with a high spatial resolution. Practical implications – The results of this research can be used as basic information for disaster mitigation and urban planning in coastal areas. Originality/value – This research creates a new approach for assessing which areas could be inundated by tsunamis, based on the vulnerability map generated through remote sensing and spatial multi-criteria analysis. Moreover, the parameters used are very close to those of actual inundation maps.

AbstractBeach vitex is a salt-tolerant, perennial, invasive shrub that has naturalized in coastal areas of the southeastern United States. Since its introduction in the 1980s, this Pacific Rim native has invaded many fragile beach-dune ecosystems along the Mid-Atlantic, Southern Atlantic, and Gulf of Mexico. Large-scale monocultures of beach vitex supplant native species through rapid vegetative reproduction and seed production. Fruits are capable of water-based dispersal, allowing for potential rapid range expansion in coastal areas. Ecosystem damage resulting from exclusion of native plant species by beach vitex and fears associated with potential negative effects on sea turtle nesting have served to promote the control and survey efforts presently underway in coastal areas of the Carolinas, Virginia, and Maryland.

Tsunami Mitigation

Many coastal structures or structures in coastal areas were destroyed by a tsunami attack. Such destructions were due primarily to the fact that such structures were not designed to withstand a tsunami. Those which were designed to withstand tsunami force may also have been destroyed due to some damaging factors which were not included in the design. The damage of the coastal structures is one of the important factors that have caused casualties. Especially, when the destroyed structures were originally aimed to mitigate the area against tsunami, they may cause higher fatalities. Examples of such structures are sea walls in many parts of Japan which were destroyed by the 2011 tsunami. This paper discusses the important factors relevant to the damage of seawall as tsunami mitigation structure such as impact force due to tsunami front, hydrostatic force, and hydrodynamic force, debris force and scour due tsunami. The study was carried out based on literature about the damages of seawall as tsunami protection structures and laboratory experiment reports. The destructions to the structures were divided into three classifications namely instantaneous direct destruction due to impact and drag forces, slowly direct destruction due to drag force, and slowly indirect destruction due to scour. Finally, important aspects to be considered in the design of seawall as tsunamis protection were proposed.

Serenting Beach is one of the beaches in the Mandalika Special Economic Zone (MSEZ), Central Lombok Regency. The MSEZ is located in the southern part of Lombok Island and faces the Indian Ocean. The Mandalika Special Economic Zone is prospected to expedite the sector of tourism at Province of West Nusa Tenggara which is very potential. A few hundred kilometers to the south part of Lombok Island is one of the large tectonic plates meeting zones which is a major source of potential tsunami earthquakes. With the geological conditions of Lombok Island which is prone to tsunamis and the existence of environmental degradation in Serenting Beach, MSEZ, it is necessary to conduct research about study of tsunami mitigation based on vegetation in Serenting Beach, MSEZ, Lombok Island. Based on the research, there are several types of plants that need to be planted as a tsunami disaster mitigation effort in Serenting Beach, MSEZ, namely: Casuarina equisetifolia, Pandanus odoratissimus, Cocos nucifera, Hibiscus tiliaceus, and Terminalia catappa. The government and various related parties need to provide education to the public, tourism managers, and tourists to take an active role in protecting vegetation and not through illegal logging.

The Impact

The first objective of this activity is to increase knowledge and understanding of the rescue procedures, evacuation routes, and emergency response plans when a large earthquake occurs. The second objective is to increase the knowledge and ability to mobilize available resources. With this knowledge and capability, the community can choose and sort out the resources that must be prioritized, so that losses can be reduced as little as possible. Referring to the results of the study, reducing the impact of earthquake and tsunami disaster risk is greatly influenced by emergency response plan factors, disaster warning system factors, knowledge factors, policy and guidance factors, and the ability of team mobilization. The conclusion obtained from the results of this activity is that the Air Rami Sub-district community gained increased knowledge and understanding of earthquake and tsunami mitigation. This can be seen from the enthusiasm of stakeholders and the public in participating in socialization activities. It is also supported by the Wilcoxon statistical test, the result showed that socialization increases public knowledge in understanding disaster mitigation, especially earthquakes and tsunamis.

The Right

The establishment of native wildflower plantings in Florida can benefit agricultural producers as well as native pollinators and other beneficial insects (predators and parasitoids). The plantings do this by:  providing forage and nesting sites for bees, butterflies, and other pollinators, increasing wild bee numbers possibly across the farm, and increasing natural enemies of insect pests (that also depend on forage and nesting sites). This document discusses choosing the right mix of native plant species to benefit many pollinator species, as well as proper site selection, planting practices, and weed control techniques. Wildflower plots should be practical to manage, maximize benefits to wildlife, and fit into the overall management practices of the property.
