Typhoon Durian, known in the Philippines as Super Typhoon Reming, was a deadly tropical cyclone that wreaked havoc in the Philippines and later crossed the Malay Peninsula in late November 2006, causing massive loss of life when mudflows from the Mayon Volcano buried many villages.
Durian first made landfall in the Philippines, packing strong winds and heavy rains that caused mudflows near Mayon Volcano. After causing massive damage in the Philippines, it exited into the South China Sea and weakened slightly, before managing to reorganise and restrengthen into a typhoon shortly before its second landfall, this time in Vietnam near Ho Chi Minh City, causing further damage of more than US$450 million. In all, Durian killed almost 2,000 people,[1] [2] and left hundreds more missing. Damages in the Philippines from the typhoon amounted to 5.086 billion PHP (US$130 million).[3]
See main article: Meteorological history of Typhoon Durian. Typhoon Durian formed as a tropical depression on November 24, 2006 near Chuuk State. Situated south of a ridge, the system tracked west-northwest through a region of low wind shear and good upper-level divergence.[4] Late on November 26, the depression intensified into a tropical storm and was named Durian by the Japan Meteorological Agency (JMA) Steady strengthening took place over the following two days as the system approached the Philippines. After attaining typhoon status on November 29, Durian underwent a period of rapid intensification,[4] culminating with it attaining peak 10 minute maximum sustained winds of 195km/h and a central barometric pressure of 915 mbar (hPa; 27.02 inHg). Durian brushed the southern coast of the Catanduanes at this intensity on November 30, where a record gust of 320km/h was observed.[5]
Slight weakening took place before the storm made landfall in the Bicol Region. Land interaction precipitated further degradation of storm, though it retained typhoon status upon emerging over the South China Sea on December 1,[4] having passed just 80km (50miles) south of Metro Manila. Some re-intensification occurred, with Durian reaching a secondary peak on December 3. Subsequently, increasingly hostile conditions caused the system to weaken to a severe tropical storm as it turned southwest. The storm had initial intensifies before struck southern Vietnam early on December 5 as a minimal typhoon before diminishing to a tropical depression. The system turned westward once again and crossed the Malay Peninsula. The JMA ceased tracking the storm on December 6 when it crossed west of 100° E and into the North Indian Ocean basin, although the Joint Typhoon Warning Center (JTWC) continued tracking it through the Bay of Bengal. Failing to reorganize, Durian degenerated into a remnant low on December 6, before ultimately dissipating three days later off the coast of Andhra Pradesh, India, on December 9.[6]
The Bicol region, where Durian first struck, is located at the southeastern portion of the Philippine island of Luzon, and is affected by an average of 8.4 tropical cyclones per year.[7] Before Durian made its damaging landfall in the Philippines, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued various tropical cyclone warnings and watches, including Public Storm Warning Signal #4 for Catanduanes, Albay, and both Camarines Sur and Norte provinces; this is the highest warning signal, in which winds of over 100 km/h (60 mph) were expected.[8] PAGASA turned off its weather radar in Virac to prevent damage. The Philippines' National Disaster Coordinating Council issued severe weather bulletins and advisories, and overall, 25 provinces in the archipelago were placed on storm alert.[9] Residents in warning areas were advised of the potential for storm surge, flash flooding, and landslides.[10]
The severe threat of the typhoon prompted over 1.3 million people to evacuate their homes, many of whom stayed in the 909 storm shelters.[10] Officials advised residents in low-lying areas to seek higher grounds. School classes in Sorsogon and in Northern and Eastern Samar were suspended,[10] and many buildings opened up as storm shelters.[11] In Naga City, about 1,500 citizens left for emergency shelters. 1,000 were evacuated elsewhere in the region,[12] including 120 in the capital city of Manila and more than 800 in Legazpi City.[9] The threat of the typhoon caused ferry, bus, and airline services to be canceled,[11] stranding thousands of people for several days.[8] All shipping traffic was halted in the Mimaropa region.[13] The Philippine Coast Guard grounded all vessels on open waters, stranding around 4,000 ferry passengers in Quezon province.[9] PAGASA turned off its weather radar in Virac to prevent damage.[11]
On November 30, while the typhoon was over the Philippines, the Central Committee for Flood and Storm Control and the National Committee for Search and Rescue sent telegraphs advising of the typhoon to search and rescue teams stationed along the entire coast of the country (Quảng Ninh province to Cà Mau). All provinces along the South China Sea were advised to assist an estimated 14,585 vessels in the path of the storm.[14] All craft were later banned from leaving harbors.[15] Requests were also made to neighboring countries to allow Vietnamese fishermen to take refuge in their ports.[16] Strong wind warnings were disseminated to residents between Phú Yên and Bà Rịa–Vũng Tàu provinces by December 2. These areas, as well as the inland provinces of Đắk Lắk, Lâm Đồng, and Bình Phước redirected all focus on the typhoon and the potential for life-threatening flash flooding.[17] Evacuation orders for southern provinces were issued by December 3, with Deputy Prime Minister Nguyễn Sinh Hùng stating, "the evacuation must be completed by Monday morning [December 4]."[15] Threatening an area not frequented by typhoons, many residents did not heed warnings as weather conditions ahead of the storm were calm. Approximately 6,800 people in Ninh Thuận province complied with the evacuation orders; however, officials requested the assistance of the Vietnamese Army to relocate roughly 90,000 people.[18] Following an unpredicted southerly shift in the storm's track towards the Mekong Delta, Hung later urged residents and officials to prepare for the storm, such that "all provinces should prepare so that we do not have another Linda."[19]
Early in its duration, Durian produced light winds on Yap in the Caroline Islands, gusting to 56km/h, as well as light rainfall totaling 52mm. Ahead of the storm, the National Weather Service on Guam issued a tropical storm warning for various islands in Yap State.[20]
Typhoon Durian affected about 3.5 million people in the Philippines,[10] of whom about 120,000 were left homeless.[21] Durian damaged 588,037 houses, including 228,436 that were destroyed, many of which were made out of wood.[10] Across the country, the storm wrecked 5,685 schools, estimated at US$63.5 million in damage. The Bicol Region accounted for 79% of the damaged schools, affecting around 357,400 children. Damage was estimated at ₱5.45 billion (PHP, US$110 million).[10] As of December 27, 2006, the death toll stood at 734, with 762 missing.[10] The International Disaster Database listed 1,399 deaths in the Philippines related to Durian, making it the second deadliest natural disaster in 2006 after an earthquake in Indonesia.
While crossing the Philippines, Durian dropped 466mm of rainfall at Legazpi, Albay in 24 hours,[22] including an hourly total of 135mm. The 24 hour total was the highest in 40 years for a station in the Bicol region.[7] Heavy rainfall caused rivers and irrigation canals to exceed their banks. Many creeks and small streams were flooded in the Bicol region.[7] Gusts were estimated as high as 260km/h.[23]
While the typhoon moved through the country, it caused complete power outages in Albay, Sorsogon, Camarines Sur, and Camarines Norte,[11] affecting tens of thousands of residents.[9] Initially, disrupted communications prevented details about the damage in the worst struck areas. The worst of the storm effects were in Albay, Camarines Sur, Catanduanes, Mindoro, and Quezon.[24] On Catanduanes Island, Durian destroyed about half of the houses in the capital city of Virac.[13] The powerful winds of the typhoon blew away houses and uprooted trees,[12] All of the trees in Bacagay were knocked down, affecting the livelihood of half of the residents. Throughout the country, about 30000ha of rice fields were destroyed,[25] accounting for 65,481 metric tons of corn; 19,420 metric tons of rice were also damaged. However, the crops were already harvested, so the storm's agriculture effects were minor.[10] The storm also wrecked 1,200 fishing boats, severely affecting the local fishing industry, and killed many livestock.[25]
The eye of Durian passed near Mayon Volcano as it struck the Bicol region. In the mountainous region, a process known as orographic lift produced heavier rainfall than near the coast, with totals possibly as high as 600 mm (24 in).[23] On November 30, the rainfall became very heavy and prolonged, saturating the soil.[7] Lahars - a type of landslide originating from a volcanic ash - formed quickly along the southern and eastern rims of Mayon Volcano, which had produced a fresh layer of ash in August 2006. The lahars destroyed dykes and dams meant to contain the debris flow,[23] which were not designed to prevent major landslides.[22] Warnings were issued for potential lahars, but the rapid development of the debris flows as well as power outages meant populations did not receive adequate warning. Initially, the lahars were contained by a layer of grasslands, although the unstable nature of the volcanic soil caused the grounds to collapse. Within 21 minutes, the lahars descended Mayon Volcano, quickly covering and wrecking six communities. After the initial series of lahars, further ash flow descended to the ocean to the north of Mayon Volcano.[23] Areas around the volcano were inundated with 1.5 m (5 ft) of floodwaters.[26] Widespread flooding was also reported in Legazpi City.[9]
North of Legazpi, the ash flow covered or damaged portions of the Pan-Philippine Highway.[23] In the small barangay - small town - of Maipon, nearby streams coalesced into a valley filled with muddy waters. The landslide arrived quickly and washed away or destroyed houses in the path. Several people died while attempting to cross to higher grounds. Similar conditions affected nearby Daraga, where 149 people died. Around that city, the landslide reached 2m (07feet) deep and 307m (1,007feet) wide, enough to cover 3 story buildings, while floods enlarged the nearby Yawa River by 600%.[7] About 13,000 families had to leave their homes due to the landslides.[27] Many roads and bridges were wrecked around the volcano, which halted transportation and impacted relief work.[28]
In Albay province alone, there were 604 deaths and 1,465 people who sustained injuries. Damage in the province totaled $71 million (USD).[29] The storm also damaged 702 of the 704 schools in the province.
Durian brought maximum 10-mins sustained winds up to 110 km/h and gusted to 150 km/h to the southern Vietnamese coastline. Strong winds capsized several boats offshore Vietnam, killing two with one missing.[30] In Bình Thuận Province alone, 820 boats sank,[31] and throughout the country 896 fishing boats sank.[32]
Heavy rainfall from the typhoon destroyed 22 schools and 1,120 houses in Bình Thuận Province. Strong winds from Durian blew off the roofs of about 500 houses in Bà Rịa–Vũng Tàu province.[31] Throughout the nation, the passage of the typhoon destroyed 34,000 homes, with an additional 166,000 damaged. Typhoon Durian killed 85 in the country and injured 1,379 others. Total damages were 7.234 trillion VND (US$450 million).[33]
On December 3, Philippine President Gloria Macapagal Arroyo declared a state of national calamity, due to the successive impacts of typhoons Xangsane, Cimaron, and Durian.[10] Arroyo ordered the immediate release of 1 billion Philippine pesos ($20.7 million, 2006 USD) for relief in areas affected by typhoons Durian, Xangsane, and Cimaron.[34] This relief fund was increased to 3.6 billion pesos ($74.8 million, 2006 USD) on December 6, including an additional 150 million pesos ($3.1 million) for power grid repair.[35] The government used over ₱500 million (PHP) from their Countryside Development Fund.[36] Soon after Durian exited the country, workers began restoring power lines and clearing debris and trees from roads,[13] which was required before relief agencies reached the hardest hit areas.[8] As of December 1, 3,316 families had fled their homes to storm shelters.[37] Immediately after the storm's landfall, reports of deaths or injuries had not yet reached the media centres.[12] As officials made contact with the hardest hit areas, the death toll quickly rose to 190 by December 1,[8] and to 720 by two weeks later.[38]
On December 17, the Philippine government issued a $46 million appeal to the United Nations for financial assistance coping with Durian.[10] This was after the country already depleted its yearly emergency funding for disasters.[39] In response, various United Nations' departments provided about $2.6 million in emergency funding, and by late December 2006, 14 countries had provided donations to the Philippines.[10] By the end of January, only 7.1% of the appeal was raised.[40] By the end of April 2007, four Asian countries - China, Indonesia, Malaysia, and Singapore - donated ₱54 million (US$2.2 million) worth of emergency supplies, such as clothing, medicine, and food.[41] [42] Various companies and local organizations donated to the relief effort, such as medicine, food, water, transport supplies, clothes, and money.[43] Individuals and corporations donated ₱68 million (US$1.4 million) in cash and supplies.[41] The international response came shortly after the calamity status was declared. On December 3, Canada released $1 million (US$860,000) for local relief through its embassy in Manila and through the International Red Cross and Red Crescent Movement.[34] [44] UNICEF donated 4,000 packages containing food, mattresses, and blankets, and UNOCHA donated $1– 2 million (USD) for relief supplies.[44] Spain donated $250,000 (USD) and sent medical teams, medicines, food, and supplies to affected areas.[45] The United States donated $250,000 plus supplies through the USAID program, and the Filipino community on Saipan contributed cash, food, and supplies.[44] Australia released $1 million (US$792,000) through its AusAID program.[44] Indonesia sent two C-130 Hercules aircraft to Legazpi City, carrying a total of 25 tons of food, medicine, and clothing valued at 1.17 billion Indonesian rupiah (US$129,000).[45] Japan pledged tents, blankets, generators, and water management equipment through the Japan International Cooperation Agency.[45] Malaysia donated 20 tons of food and medicines, and Singapore sent two batches of supplies valued at $50,000 (USD) through Singapore Airlines.[44] The Republic of Korea pledged $100,000 (USD) cash, while the People's Republic of China pledged $200,000 (USD).[45] Israel donated $7,500 (USD), mostly in medicines and medical supplies.[45]
The Red Cross, which responded to the repeated storms of 2006, launched an appeal that raised $9.67 million for the Philippines. In March 2009, the agency completed the missions responding to the 2006 storms and transferred the remaining funds to help repair from Typhoon Fengshen in 2008.[46] The International Organization for Migration developed the Humanitarian Response Monitoring System in response to problems in the management of the aftermath of Durian,[47] and also provided 12,750 metric tons of building supplies, medicine, and water in the storm's immediate aftermath. OXFAM built 242 latrines and 99 bath houses to ensure proper hygiene. The Tzu Chi Foundation set up a temporary medical camp in Tabaco to provide free health care to storm victims.[48] The International Labour Organization built a livelihood center in February 2008 to help provide jobs to storm victims.[49] The World Bank, in conjunction with the Philippines' National Power Corporation, funded a $21.6 million project to repair the damaged power lines in the typhoons' aftermath. The agencies also upgraded 118 electrical towers by 2008 to stabilize power supply during typhoons. As a result, there were minimal power outages during the passage of Tropical Storm Higos (Pablo) in 2008.[50]
Beginning in January 2007, the United Nations Food and Agriculture Organization distributed about 150 packs of vegetable seeds and farm tools to displaced residents in three Bicol provinces, as part of the sustainable recovery program planned by the Philippine government for storm victims.[51] [25] By a year after the typhoon, farmers had regrown their rice and vegetables, utilizing a rebuilt irrigation system. The World Food Programme supplied fishermen with materials to rebuild damaged boats, allowing them to resume catching fish by May 2007.[25] The agency also provided monthly food rations to displaced residents in Albay,[52] totaling 294 tons of rice to about 6,000 families;[53] however, the food distribution programs ended in December 2007, causing food shortages in the first few months of 2008 among those still displaced.[27] UNICEF distributed 1,750 water purification tablets, along with jerrycans and water containers, to ensure access to clean water.
After the successive impacts of Xangsane and Durian caused widespread power outages, the Bicol region lost about $250 million in economic output.[50] The unemployment rate in the Bicol region rose to about 30%, and many who retained their jobs earned less than before the storm.[49] In the aftermath of Durian, all relief activities were coordinated through the Philippines' departments of Health and Social Welfare and Development. A fleet of over 200 vehicles transported relief supplies - food, construction materials, clothing, and medicine - to the Bicol region on December 12. The Philippine Air Force airlifted supplies and medical teams to Bicol and offshore Catanduanes, with the National Disaster Coordinating Council supplying 17,350 sacks of rice to those areas. The Departments of Social Welfare and Development and the Department of Health sent teams to help victims cope with stress and consoled the families of the deceased, aided by psychiatrists. The Department of Health also distributed tents and sleeping bags, provided vaccines to people in evacuation camps, and ensured proper burial of storm casualties. There was a minor outbreak of diarrhea in the evacuation camps that affected 142 people in Legazpi, and other evacuees were also ailed by the cold, coughing, and fever. Local governments in Albay worked to ensure areas retained clean water by using disinfectants and temporary latrines.[10] The Philippine government provided ₱119 million (US$2.4 million) toward rebuilding the damaged schools in Albay, only 23% of the required cost to repair all of the schools.
The government assessed that about 35% of those who lost their houses had the resources to rebuild without assistance; this meant that 144,692 houses had to be rebuilt.[40] Many of the storm victims left homeless resided in tent camps, schools, and temporary shelters, until more permanent buildings were built.[27] [54] The Red Cross housed about 60,000 people across ten provinces in temporary shelters.[55] The Philippine government planned to quickly build more permanent homes, although there were difficulties in securing land and materials for the new housing. By March 2007, government and international agencies only provided 6.9% of the necessary homes, forcing people to stay in shelters longer than expected.[54] By a year after the storm, over 10,000 families still stayed in transit camps in Albay and Camarines Sur.[56] Various organizations helped the homeless secure housing. The government of Italy funded a ₱26 million (US$525,000) project to rebuild 180 houses in Albay. The Italian government also helped build new livelihood centers to provide jobs, provided new boats, and donated about 80,000 coconut seeds to replant trees.[57] In the eight months after Durian struck, the Philippine National Red Cross, in conjunction with the International Red Cross, delivered building supplies to about 12,000 families to repair their homes or build new ones. The organizations encouraged residents to rebuild houses away from vulnerable areas.[58] The International Organization for Migration, in conjunction with the United States Agency for International Development, built 907 homes and new community centers.[59] The Philippine government released ₱76 million ($1.5 million) in funds to build 1,089 houses.[60] UNICEF provided emergency funding to rebuild 50 daycare centers that were damaged by the typhoon.[61] Habitat for Humanity helped repair about 1,200 homes,[62] build about 2,000 new houses, and rebuilt four schools in Sorsogon.[63]
Around Mayon Volcano, officials enacted search and rescue missions for victims affected by landslides.[10] Workers quickly excavated lahar-filled valleys, bridges, and river beds to rebuild dykes. Farmers quickly regrew damaged crops, while schools and homes were cleaned and rebuilt. Stronger concrete dykes were built around populated communities.[23] The government developed relocation plans for three landslide-prone areas in Albay.[10] In 2011, the Regional Development Council approved a budget to construct additional dams along the Mayon Volcano to prevent the deadly floods and landslides that occurred during Durian.[64] Dams were scheduled to be constructed around the volcano after a 1981 study, but these were delayed due to budget constraints.[7]
In Vietnam, which had recently been affected by Typhoon Xangsane, the national government released 150 billion Vietnamese đồng ($9 million, 2006 USD) in food and supplies to families in affected areas.[65] The United States donated $100,000 (USD), and its Oxfam organisation donated $200,000 (USD) to the most affected provinces.[65] The International Red Cross and Red Crescent Movement launched an emergency appeal for $2.47 million (USD) to support the efforts of the Vietnam Red Cross, which distributed over 2,000 packets of supplies and over 2 tonnes of rice, medicine, and clothes.[66]
The 39th session of the United Nations Economic and Social Commission for Asia and the Pacific/World Meteorological Organization's Typhoon Committee met in Manila, Philippines from December 4 - 9, soon after the onslaught of the floods from Durian. The committee's regional director stated in their report, "I wish to extend WMO’s sincere condolences and sympathy to your Government and to the Philippine people who were adversely affected by the past typhoons." During the session, the committee retired the name Durian,[67] replacing it with Mangkhut in 2008;[68] which was later retired after its usage in 2018.[69]
PAGASA also retired the local name "Reming" in 2006 and replaced it with "Ruby",[70] which was also later retired following its usage in 2014.[71]
