A natural disaster is the highly harmful impact on a society or community following a natural hazard event. Some examples of natural hazard events include: flooding, drought, earthquake, tropical cyclone, lightning, tsunami, volcanic activity, wildfire. A natural disaster can cause loss of life or damage property, and typically leaves economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available. Scholars have been saying that the term natural disaster is unsuitable and should be abandoned. Instead, the simpler term disaster could be used, while also specifying the category of hazard. A disaster is a result of a natural or human-made hazard impacting a vulnerable community. It is the combination of the hazard along with exposure of a vulnerable society that results in a disaster.
The 2000 Mozambique flood was a natural disaster that occurred in February and March 2000. The catastrophic flooding was caused by heavy rainfall caused by Cyclone Leon-Eline that lasted for four weeks and made many homeless. Approximately 800 people died, 1400 km2 of arable land was affected and 20,000 head of cattle and food were lost. It was the worst flood in Mozambique in 50 years. The government of Mozambique distributed 15 million dollars to its citizens to account for damage property and loss of income.
The 1970 Bhola cyclone was a devastating tropical cyclone in the Bengal region, that struck East Pakistan and India's West Bengal on November 12, 1970. It remains the deadliest tropical cyclone ever recorded and one of the world's deadliest humanitarian disasters. At least 300,000 people died in the storm, possibly as many as 500,000, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. Bhola was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season.
Typhoon Chataan, known in the Philippines as Typhoon Gloria, was the deadliest natural disaster in the history of Chuuk, a state in the Federated States of Micronesia (FSM). The typhoon formed on June 28, 2002, near the FSM, and for several days it meandered while producing heavy rainfall across the region. On Chuuk, the highest 24-hour precipitation total was 506 mm (19.9 in), which was greater than the average monthly total. The rain produced floods up to 1.5 m (4.9 ft) deep, causing landslides across the island that killed 47 people. There was also one death on nearby Pohnpei, and damage in the FSM totaled over $100 million.
Typhoon Saomai, known in the Philippines as Super Typhoon Juan, was considered the most powerful typhoon on record to strike the east coast of the People's Republic of China. It was the eighth tropical storm, fifth typhoon, and third super typhoon of the 2006 Pacific typhoon season recognized by the Joint Typhoon Warning Center. According to the Japan Meteorological Agency, Saomai was the seventh tropical storm and fifth typhoon of the season. The name "Saomai" was submitted by Vietnam, and is from the Vietnamese word for "morning star", a reference to the planet Venus.
Typhoon Xangsane, known in the Philippines as Typhoon Milenyo, was a typhoon that affected the Philippines, Vietnam, and Thailand during the 2006 Pacific typhoon season. The name Xangsane was submitted by Laos and means elephant.
Extremely Severe Cyclonic Storm Sidr was a tropical cyclone that resulted in one of the worst natural disasters in Bangladesh. The fourth named storm of the 2007 North Indian Ocean cyclone season, Sidr formed in the central Bay of Bengal, and quickly strengthened to reach peak 1-minute sustained winds of 260 km/h (160 mph), making it a Category-5 equivalent tropical cyclone on the Saffir–Simpson scale. The storm eventually made landfall in Bangladesh on November 15, 2007, causing large-scale evacuations. At least 3,447 deaths have been blamed on the storm, with some estimates reaching 15,000.
Severe Tropical Storm Linda, also known as Typhoon Linda, Cyclonic Storm Linda , or in the Philippines as Tropical Depression Openg, was the worst typhoon in southern Vietnam in at least 100 years, killing thousands of people and leaving extensive damage. It formed on October 31, 1997, in the South China Sea, between Indochina and the Philippines. Strengthening as it moved westward, Linda struck extreme southern Vietnam on November 2 with winds of 65 mph (105 km/h), dropping heavy rainfall. Once in the Gulf of Thailand it strengthened further to minimal typhoon status, but weakened to tropical storm strength before crossing the Malay Peninsula into the Bay of Bengal, the first storm to do so in five years. It restrengthened in the Indian Ocean to typhoon status, but increasing wind shear and weakened steering currents caused Linda to dissipate on November 9.
The 2010 Mentawai earthquake occurred with a moment magnitude of 7.8 on 25 October off the western coast of Sumatra at 21:42 local time. The earthquake occurred on the same fault that produced the 2004 Indian Ocean earthquake. It was widely felt across the provinces of Bengkulu and West Sumatra and resulted in a substantial localized tsunami that struck the Mentawai Islands.
In late October 2010, Mount Merapi in border of Central Java and Special Region of Yogyakarta, Indonesia began an increasingly violent series of eruptions that continued into November. Seismic activity around the volcano increased from mid-September onwards, culminating in repeated outbursts of lava and volcanic ash. Large eruption columns formed, causing numerous pyroclastic flows down the heavily populated slopes of the volcano. The 2010 eruption of Merapi was the volcano's largest since 1872.
Typhoon Rananim, known in the Philippines as Typhoon Karen, was the strongest typhoon to make landfall on the Chinese province of Zhejiang since 1956. It formed on August 6, 2004, intensifying into a tropical storm on August 8. Rananim gradually intensified, initially moving northward before turning to the northwest and attaining typhoon status. After developing a small eye, the typhoon attained peak winds of 150 km/h (93 mph) as it passed between Taiwan and Okinawa. On August 12, Rananim moved ashore in China, and it dissipated three days later. The name Rananim means "hello" in the Chuukese language.
Intense Tropical Cyclone Japhet was a damaging tropical cyclone that affected southeast Africa in March 2003. It developed on February 25 near the southwest coast of Madagascar, and initially moved to the northwest before turning to the southwest. With favorable conditions for development, Japhet quickly intensified in the Mozambique Channel, reaching maximum winds of 175 km/h (109 mph), sustained over 10 minutes. After stalling briefly, the cyclone turned to the northwest, weakening slightly before striking Mozambique just south of Vilankulo on March 2. Japhet slowly weakened while progressing inland, dissipating over Zambia on March 6.
Flooding in Jakarta occurs on the northwest coast of Java, at the mouth of the Ciliwung River on Jakarta Bay, which is an inlet of the Java Sea and has happened recently in 1996, 1999, 2007, 2013, and 2020.
Cyclonic Storm Viyaru, operationally known as Cyclonic Storm Mahasen, was a relatively weak tropical cyclone that caused loss of life across six countries in Southern and Southeastern Asia. Originating from an area of low pressure over the southern Bay of Bengal in early May 2013, Viyaru slowly consolidated into a depression on May 10. The depression gained forward momentum and attained gale-force winds on May 11 and was designated as Cyclonic Storm Viyaru, the first named storm of the season. Owing to adverse atmospheric conditions, the depression struggled to maintain organized convection as it moved closer to eastern India. On May 14, the exposed circulation of Viyaru turned northeastward. The following day, conditions again allowed for the storm to intensify. Early on May 16, the cyclone attained its peak intensity with winds of 85 km/h (55 mph) and a barometric pressure of 990 mbar. Shortly thereafter Viyaru made landfall near Chittagong, Bangladesh. On May 17, it moved over the eastern Indian state of Nagaland.
In May 2003, a tropical cyclone officially called Very Severe Cyclonic Storm BOB 01 produced the worst flooding in Sri Lanka in 56 years. The first storm of the 2003 North Indian Ocean cyclone season, it developed over the Bay of Bengal on May 10. Favorable environmental conditions allowed the system to intensify steadily while moving northwestward. The storm reached peak maximum sustained winds of 140 km/h (85 mph) on May 13, making it a very severe cyclonic storm according to the India Meteorological Department (IMD), which is the official Regional Specialized Meteorological Center for the basin. The cyclone drifted north over the central Bay of Bengal, gradually weakening due to heightened wind shear. Turning eastward, the storm deteriorated to a deep depression on May 16 before it curved northeastward and re-intensified into a cyclonic storm. It came ashore in western Myanmar and dissipated over land the following day.
