2004 Indian Ocean earthquake and tsunami in the context of "Aceh"

The Singapore Armed Forces (SAF) are the military of the Republic of Singapore, responsible for protecting and defending the security interests and the sovereignty of the country. A component of the Ministry of Defence (MINDEF), the armed forces have four service branches: the Army, Navy, Air Force, and Digital and Intelligence Service. An integrated force, it is the most capable, robust, technologically sophisticated and powerful military in the Southeast Asia region. The SAF is headed by the chief of defence force, appointed by the President, on the advice of the Cabinet.

Since its inception, the SAF has been involved in various operations, both domestically and abroad. These include peacekeeping missions in places such as Afghanistan, Iraq and Timor Leste as well as disaster relief operations in various countries, including the 1970 Bhola cyclone, 2004 Indian Ocean earthquake and tsunami, Hurricane Katrina, 2008 Sichuan earthquake, April 2015 Nepal earthquake, Hurricane Harvey, among others. In addition, the SAF has assisted the United Nations to oversee and supervise the electoral process in countries such as Cambodia, Ethiopia, Namibia and South Africa.

The Andaman Sea (historically also known as the Burma Sea) is a marginal sea of the northeastern Indian Ocean bounded by the coastlines of Myanmar and Thailand along the Gulf of Martaban and the west side of the Malay Peninsula, and separated from the Bay of Bengal to its west by the Andaman Islands and the Nicobar Islands. Its southern end is at Breueh Island just north of Sumatra, with the Strait of Malacca further southeast.

Traditionally, the sea has been used for fishery and transportation of goods between the coastal countries and its coral reefs and islands, which are popular tourist destinations. The fishery and tourist infrastructure was severely damaged by the December 2004 Indian Ocean earthquake and tsunami.

A tsunami (/(t)suːˈnɑːmi, (t)sʊˈ-/ (t)soo-NAH-mee, (t)suu-; from Japanese: 津波, lit. 'harbour wave', pronounced [tsɯnami]) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event.

Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give the false impression of a causal relationship between tides and tsunamis. Tsunamis generally consist of a series of waves, with periods ranging from minutes to hours, arriving in a so-called "wave train". Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous, and they can affect entire ocean basins. The 2004 Indian Ocean tsunami was among the deadliest natural disasters in human history, with at least 230,000 people killed or missing in 14 countries bordering the Indian Ocean.

Seismology (/saɪzˈmɒlədʒi, saɪs-/; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies. It also includes studies of the environmental effects of earthquakes such as tsunamis; other seismic sources such as volcanoes, plate tectonics, glaciers, rivers, oceanic microseisms, and the atmosphere; and artificial processes such as explosions.

Paleoseismology is a related field that uses geology to infer information regarding past earthquakes. A recording of Earth's motion as a function of time, created by a seismograph is called a seismogram. A seismologist is a scientist who works in basic or applied seismology.

Disasters can have high costs associated with responding to and recovering from them. This page lists the estimated economic costs of relatively recent disasters.

The costs of disasters vary considerably depending on a range of factors, such as the geographical location where they occur. When a large disaster occurs in a wealthy country, the financial damage may be large, but when a comparable disaster occurs in a poorer country, the actual financial damage may appear to be relatively small. This is in part due to the difficulty of measuring the financial damage in areas that lack insurance. For example, the 2004 Indian Ocean earthquake and tsunami, with a death toll of around 230,000 people, cost a "mere" $15 billion, whereas in the Deepwater Horizon oil spill, in which 11 people died, the damage was six times higher.

The Quadrilateral Security Dialogue, sometimes referred to as the Quad is a grouping of Australia, India, Japan, and the United States that is maintained by talks between member countries. The Australian government states that the aim of the partnership is to support 'a peaceful, stable and prosperous Indo-Pacific that is inclusive and resilient'.

The grouping follows the "Tsunami Core Group" and its "new type of diplomacy" developed in response to the 2004 Indian Ocean earthquake and tsunami. It was initiated in 2007 by Japanese Prime Minister Shinzo Abe, with the support of Australian prime minister John Howard, Indian prime minister Manmohan Singh and U.S. vice president Dick Cheney. The dialogue was paralleled by joint military exercises of an unprecedented scale, titled Exercise Malabar. The diplomatic and military arrangement was widely viewed as a response to increased Chinese economic and military power.

The Vargas tragedy was a natural disaster that occurred in Vargas State (today La Guaira), Venezuela on 15 December 1999 (over the course of 10 days), when torrential rains caused flash floods and debris flows that killed tens of thousands of people, destroyed thousands of homes, and led to the complete collapse of the state's infrastructure. According to relief workers, the neighborhood of Los Corales was buried under 3 meters (9.8 ft) of mud and a high percentage of homes were simply swept into the ocean. Entire towns including Cerro Grande and Carmen de Uria completely disappeared. As much as 10% of the population of Vargas died during the event. A deadlier natural disaster would not occur until the 2004 Indian Ocean earthquake and tsunami. According to Guinness World Records, it is the deadliest mudslide ever recorded.
