MANILA - The storm surge that devastated Tacloban City and many parts of the Visayas on November 8 was not a unique phenomenon. The storm surge flood map based on the surveyed water limit points for Haiyan in 2013 did not match the storm surge hazard map provided by the municipality of Tanauan. Updates as of Tuesday, Nov. 12 Busuanga The United Nations reported severe damage to housing and public infrastructure, and said that food and water would run out in two days. In other words, the stronger the winds or the larger the storm the higher the surge. The storm surge simulation maps identify the parts of your community which will be reached by a storm surge. Philippines - Modelled Storm Surge Map of Quezon - 2 metres height - NOAH Storm Surge Hazard maps based on predicted storm surge height. : Identification of storm surge vulnerable areas in the Philippines Figure 1. The 4 groups are SSA 1 (0.01m to 2m), SSA 2 (2.01m to 3m), SSA 3 (3.01m to 4m), and SSA 4 (4m and above). Haiyan was a super Storm surge both destroys built infrastructure, like roads,a nd undermines foundations and building structures. You are in the STAGING environment. Philippines - Modelled Storm Surge Map of Quezon - 2 metres height - NOAH Storm Surge Hazard maps based on predicted storm surge height. A storm surge is the rising of the sea level associated with the passing of a tropical storm or typhoon. It is measured as the rise in water level above the normal tidal level, and does not include waves. Storm surges are caused primarily by high winds pushing on the ocean’s surface. 3 .

The storm surge inundation map can also be used as basis for disaster preparedness plans of coastal communities threatened by approaching typhoons. A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. The flooding accompanying the storm surge is the main threat to the lives and infrastructure of those Filipinos living near the coast, especially those residing in in low lying coastal areas on the Eastern side of the Philippine archipelago. Storm surge is responsible for significant property damage and loss of life as part of cyclones. 1.

Maximum storm surge height (m) map for the (a) Philippines, (b) Metro Manila, (c) Iloilo, (d) Leyte. This is due to the push of strong winds on the water surface, the piling up of big waves, pressure setup and astronomical tide moving towards the shore. This is due to PAGASA DOST the push of strong winds on the water surface (wind When a tropical cyclone reaches landfall it can bring a deadly surge of water generated by a rise in sea level caused by the storm. But perhaps other other definitions are welcome as long as proper citation is included. using the data gathered during the surveys in reference to the significant tropical cyclone occurrences and from storm surge model results. The Storm Surge Hazard Map shows areas of different inundations categorized as: 1-meter surges; 1-meter to 4-meter surges; and, 4-meter to 12-meter surges. This extreme event emphasized the necessity to forecast storm surge height and inundation in the Philippine coastal regions. Surge levels were computed using Delft3D two days after landfall. The model shows maximum surge levels over 5 metres near Tacloban City (tides were not included). On the western coast of Samar, the storm surge … The tsunami hazard data is from Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), 2008. Storm Surge Advisory 4 Source : Project NOAH and subject to ground validation. erating an average of 26 tropical cyclones per year (National Oceanic and … Storm surge forms primarily on the right side of the storm track (in the Northern Hemisphere) because the cyclone's rotation and its steering winds move in the same direction there and push water ahead. For storm-surge prone communities, the most important considerations are: 1. The maps produced show the storm-surge-vulnerable areas in Metro Manila, illustrated by the flood depth of up to 4 m and extent of up to 6.5 km from the coastline. Disaster Risk; SENDAI Framework; Countries & Regions; Themes; Hazards By 7th November, storm signal warnings had been raised by PAGASA, including storm surge warnings in many parts of the country. The project completed all 67 coastal provinces in the country using a 1:20,000 scale Digital Terrain Model from NAMRIA as a base map for the storm surge hazard simulations. Waves of 4.6 m (15 ft) were also estimated. Select and confirm item options from the list below before adding it to cart, NOAH works to raise Filipinos' awareness of natural hazards. Along the airport, a storm surge of 4 m (13 ft) was estimated. The storm surge map of Tanauan, which is shown in Fig. The wind fields are based on JTWC data. The inundation coverage is estimated based on geomorphologic analysis and observation in the areas during interviews or surveys. The study’s objective is to identify the areas in the Philippines that are most susceptible to MANILA - The storm surge that devastated Tacloban City and many parts of the Visayas on November 8 was not a unique phenomenon. It is this combined effect of low pressure and persistent wind over a shallow water body which is the most common cause of storm surge flooding problems. The storm tide levels were categorized into four groups based on their peak height to create the SSA – SSA 1 (2.01m to 3m), SSA 2 (3.01m to 4m), SSA 3 (4.01m to 5m), and SSA 4 (5m and above). Storm Surge Advisory 1 (SSA1): 2 meters Other countries are also working on improving storm surge forecasts, including the US, where the National Hurricane Center this year introduced an experimental map for the East and Gulf Coasts, and Mr. Lagmay’s team is working closely with them to beef up the Philippines’ own storm-surge advisory system. If we ask ourselves where in the world the greatest threat from storm surge is, the Philippines may not immediately come to mind. Dev’t. This is due to the push of strong winds on the water surface, the piling up of big waves, pressure setup and astronomical tide moving towards the shore.

The flood area is shown in pink in Fig. 1474 J. P. Lapidez et al. Although Typhoon Haiyan was a weather hazard which had an impact on several countries, the Philippines bore the brunt of the damage. The wind causes the water to pile up higher than the ordinary sea level. Low pressure at the center of a weather system also has a small secondary effect, as can the bathymetry of the body of water. Identification of storm surge vulnerable areas in the Philippines through the simulation of Typhoon Haiyan-induced storm surge levels over historical storm tracks J. P. Lapidez1, J. Tablazon1, L. Dasallas1, L. A. Gonzalo1, K. M1, 11 Furthermore, the official storm surge hazard map did not consider storm surges with a height of 7 meters (the forecasted height of PAGASA) and therefore it was not possible to relate this map to the predicted surge. proper citations be referred to the sources mentioned above; and, c.) all logos appearing on the map should also appear on your document. The storm tide levels are then categorized into 4 groups which is based on its peak height, this is done to create a storm surge advisory (SSA) based on the probable storm tide height.
