Indian Ocean Tsunami Warning System
The Indian Ocean Tsunami Warning System, abbreviated as IOTWS, was set up to provide warning to inhabitants of nations bordering the Indian Ocean of approaching tsunamis. The tsunami warning system has been in use since the mid-2000s. Background A warning system for the Indian Ocean was prompted by the 2004 Indian Ocean earthquake and resulting tsunami, which left approximately 250,000 people dead or missing. Many analysts claimed that the disaster would have been mitigated if there had been an effective warning system in place, citing the well-established Hawaii-based Pacific Tsunami Warning Center, which operates in the Pacific Ocean. People in some areas would have had more than adequate time to seek safety if they were aware of the impending catastrophe. The only way to effectively mitigate the impact of a tsunami is through an early warning system. Other methods such as sea walls only work for a percentage of waves, but a warning system is effective for all waves originat ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Early Warning Programme
The International Early Warning Program (IEWP), was first proposed at the Second International Early Warning Conference (EWCII) in 2003 in Bonn, Germany. It developed increasing importance in the wake of the 2004 Indian Ocean tsunami, which claimed over 200,000 lives and injured over half a million people. History In January 2005, the United Nations (UN) launched extensive plans to create a global warning system to lessen the impact of deadly natural disasters at the World Conference on Disaster Reduction, held in Kobe, Japan. The UN programme would help improve prevention and resilience to all types of natural disasters, including droughts, wildfires, floods, typhoons, hurricanes, landslides, volcanoes and tsunamis, by using a comprehensive set of methods including rapid information sharing and training communities at risk. It is believed that the loss of human life would have been dramatically reduced, if a tsunami warning system, like the one that exists for the volcano-and ...

Warning Systems
A warning system is any system of biological or technical nature deployed by an individual or group to inform of a future Risk, danger. Its purpose is to enable the deployer of the warning system to prepare for the danger and act accordingly to mitigate or avoid it. Warnings cannot be effective unless people react to them. People are more likely to ignore a system that regularly produces false warnings (the The Boy Who Cried Wolf, cry-wolf effect), but reducing the number of false warnings generally also increases the risk of not giving a warning when it is needed. Some warnings are non-specific: for instance, the probability of an earthquake of a certain magnitude in a certain area over the next decade. Such warnings cannot be used to guide short-term precautions such as evacuation. Opportunities to take long-term precautions, such as better building codes and disaster preparedness, may be ignored. Biological warning systems *Aposematism (e.g. warning coloration) *Climate can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Management In Asia
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediate threat to life, he ...

2018 Sunda Strait Tsunami
The 2018 Sunda Strait tsunami ( Indonesian: ''Tsunami Selat Sunda 2018'') occurred on 22 December 2018 at around 21:38 local time after large parts of the southwestern side of Anak Krakatoa collapsed onto its caldera. The landslide spawned a tsunami wave that struck multiple coastal regions in Banten and Lampung, including the tourist destination of Anyer. Lack of warnings on the arrival of the tsunami, coinciding with the Christmas and New Year holiday season in the nation and the tsunami occurring at nighttime, contributed to the large loss of life. With 426 deaths, the tsunami was the deadliest volcanic tsunami in Indonesia since the 1883 Krakatoa tsunami, which originated from the same island.Benazir, Comfort, L.K., Luthfi, M, Supasri, A, Syamsidik.

2012 Indian Ocean Earthquakes
The 2012 Indian Ocean earthquakes were Moment magnitude scale, magnitude 8.6 and 8.2 Submarine earthquake, undersea earthquakes that struck near the Indonesian province of Aceh on 11 April at 15:38 local time. Initially, authorities feared that the initial earthquake would cause a tsunami and warnings were issued across the Indian Ocean; however, these warnings were subsequently cancelled. These were unusually large intraplate earthquakes and the largest strike-slip earthquake ever recorded. Tectonic setting The 2012 earthquake's epicenter was located within the Indo-Australian plate, which is divided into two sub- or proto-plates: the Indian, and Australian. At their boundary, the Indian and Australian plates converge at per year in a NNW–SSE direction. This convergence is accommodated by a broad zone of wikt:diffuse, diffuse deformation. As part of that intraplate deformation, north–south trending fracture zones have been reactivated from the Ninety East Ridge as far e ...

2006 Pangandaran Earthquake And Tsunami
An earthquake occurred on July 17, 2006, at along a subduction zone off the coast of West Java, west and central Java, a large and densely populated island in the Indonesian archipelago. The shock had a Moment magnitude scale, moment magnitude of 7.7 and a maximum perceived intensity of Mercalli intensity scale, IV (''Light'') in Jakarta, the Capital (political), capital and largest city of Indonesia. There were no direct effects of the earthquake's shaking due to its low intensity, and the large loss of life from the event was due to the resulting tsunami, which inundated a portion of the Java coast that had been unaffected by the earlier 2004 Indian Ocean earthquake and tsunami that was off the coast of Sumatra. The July 2006 earthquake was also centered in the Indian Ocean, from the coast of Java, and had a duration of more than three minutes. An abnormally slow rupture at the Sunda Trench and a tsunami that was unusually strong relative to the size of the earthquake were b ...

Cell Broadcast
Cell Broadcast (CB) is a method of simultaneously sending Short Message Service, short messages to multiple mobile telephone users in a defined area. It is defined by the ETSI's GSM committee and 3GPP and is part of the 2G, 3G, 4G and 5G standards. It is also known as Short Message Service-Cell Broadcast (SMS-CB or CB SMS). Unlike Short Message Service-Point to Point (SMS-PP), Cell Broadcast is a Point-to-multipoint communication, one-to-many geo-targeted and geo-fenced messaging service. Cell Broadcast technology is widely used for Emergency population warning, public warning systems. History Cell Broadcast messaging was first demonstrated in Paris in 1997. Some mobile operators used Cell Broadcast for communicating the area code of the antenna cell to the mobile user (via channel 050), for nationwide or citywide alerting, weather reports, mass messaging, location-based service, location-based news, etc. Cell broadcast has been widely deployed since 2008 by major Asian, US, Ca ...
