“…Some articles on coastal vegetation and resource destructions by tsunami mainly based on remote sensing and geographic information system. Chen et al (2005), Shofiyati et al (2005), Iverson and Prasad (2007), and Liew et al (2010) provided such examples. It should be noted that coastal vegetation studies in Northern Sumatra were very limited, both before and after the Indian Ocean tsunami disaster.…”

Abstract. Onrizal, Mansor M. 2015. Status of coastal forests of the Northern Sumatra in 2005 (after 2004's tsunami catastrophe).Biodiversitas 17: 44-54. The first intensive ecological study of coastal vegetation including mangrove, littoral and peat swamp forests after the 2004 tsunami catastrophe in Northern Sumatra was conducted from January to December 2005 where 16 sampling sites along 2960km coastline in Northern Sumatra were selected. In each site, one quadrate of 100 m x 100 m was established and divided into 10 m x 10 m subplots where all standing trees of ≥ 2 cm diameter at breast height (DBH) were identified to species level and measured. Overall 54,871 standing trees were recorded in 16 sites comprising 84 species in 65 genera and 37 families. Mangrove trees Rhizophora apiculata and R. mucronata were widely distributed and are dominant in most of the sampling sites. This indicated that these species have stronger resilient compared to other species. The highest value of Shannon-Wiener index of species and Evenness index of species was 3.03 and 0.85, respectively. It means that some sites were rich in biodiversity which harbors various species of plants. Subsequently, undisturbed coastal forests including mangroves, littoral forests and peat swamp forests characterized by dense stands, mixed species and structures play an important role in coastal protection against tsunami. Therefore, the coastal vegetation is needed to conserve the biodiversity and to maintain the production capacity as part of sustainable and longlasting vegetation bioshield.

“…High-resolution satellite imagery was widely employed in assessing damage caused by the 2004 Indian Ocean tsunami (Borrero, 2005;Chen et al, 2005;Ghosh et al, 2005;Miura et al, 2006). SPOT images were used in conjunction with IKONOS images for groundtruthing and change/damage detection to allow for rapid disaster response and assessment through measurements of tsunami inundation depth, run up height, and area of affected land (Chen et al, 2005).…”

Borrero (2005) combined QuickBird imagery and digital elevation models to assess the run up height (elevation above sea level), inundation distance, shoreline erosion, and co-seismic subsidence of the tsunami in Banda Aceh, Sumatra.…”

Since 2000, there have been a number of spaceborne satellites that have changed the way we assess and predict natural hazards. These satellites are able to quantify physical geographic phenomena associated with the movements of the earth's surface (earthquakes, mass movements), water (floods, tsunamis, storms), and fire (wildfires). Most of these satellites contain active or passive sensors that can be utilized by the scientific community for the remote sensing of natural hazards over a number of spatial and temporal scales. The most useful satellite imagery for the assessment of earthquake damage comes from high-resolution (0.6 m to 1 m pixel size) passive sensors and moderate resolution active sensors that can quantify the vertical and horizontal movement of the earth's surface. High-resolution passive sensors have been used to successfully assess flood damage while predictive maps of flood vulnerability areas are possible based on physical variables collected from passive and active sensors. Recent moderate resolution sensors are able to provide near real time data on fires and provide quantitative data used in fire behavior models. Limitations currently exist due to atmospheric interference, pixel resolution, and revisit times. However, a number of new microsatellites and constellations of satellites will be launched in the next five years that contain increased resolution (0.5 m to 1 m pixel resolution for active sensors) and revisit times (daily ≤ 2.5 m resolution images from passive sensors) that will significantly improve our ability to assess and predict natural hazards from space.

“…De la misma forma que las geoformas submarinas modifi can los trenes de ondas y su incidencia en la costa, las geoformas y los ecosistemas costeros juegan un rol relevante en la mitigación de los impactos de un tsunami, estos ya han sido demostrados en casos como Japón, Sri Lanka e Indonesia, especialmente a través del rol de humedales costeros (Chen, et al, 2005;Danielsen et al, 2005: Tanaka et al, 2007Chatenoux & Peduzzi, 2007). Playas, dunas y humedales atenúan la velocidad y altura de inundación y por lo tanto su poder destructivo, situación que en el área de estudio presentan alta degradación, en especial dada la tendencia erosiva de la costa de Escuadrón (Martínez, 2013a).…”

RESUMENSe evalúa el riesgo de inundación por tsunami en la localidad de Boca Sur, comuna de San Pedro de La Paz (37ºS), Región del Biobío. Se consideró un escenario extremo de tsunami generado por un sismo de magnitud Mw= 9.0. La inundación por tsunami se obtuvo mediante modelación numérica usando el código NEO-WAVE con 4 mallas anidadas de diferente resolución espacial y topo-batimetría de detalle. El análisis de vulnerabilidad consideró las dimensiones física, socioeconómica y organizacional, con datos obtenidos a través del Instituto Nacional de Estadística a nivel de manzana censal y encuestas a la población. Se determinó que el primer tren de ondas llega a la costa luego de 22 minutos de ocurrido el terremoto, alcanzando la cota de 5 msnm y alturas de fl ujo de hasta 2 m. Los factores de vulnerabilidad que explican el riesgo se asociaron a una alta precariedad de la vivienda, bajo nivel de bienestar social, alta densidad poblacional y bajo nivel de organización comunitaria de la población en caso de evacuación frente a tsunamis.Palabras clave: Costa, desastres socionaturales, vulnerabilidad social, planifi cación Territorial ABSTRACTWe assessed the risk of fl ooding due to tsunamis in the Boca Sur neighborhood, located in the Municipality of San Pedro de la Paz (37°S), Biobio region. We considered an extreme tsunami scenario generated by an earthquake of magnitude Mw 9.0. The tsunami inundation was obtained by means of the NEOWAVE model with 4 nested grids and detail topo-bathymetry data. The vulnerability analysis considered both physical, socioeconomical and organizational dimensions from statistical data given by the National Institute of Statistics (INE for its name in Spanish) at a block level as well as a fi eld survey. Results show that the fi rst tsunami waves would arrive 22 min post-earthquake and the maximum inundation reach up to 5 m above the mean water level with a fl ow depth of 2m. The risk level can be explained by several variables related to the vulnerability, namely, the prevalence of poor housing conditions, low level of social welfare, high population density and low level of community organization in case of necessary tsunami evacuation.
