Transcript of "Early Warning System"

  1. 1. Early Warning Systems
  2. 2. Thought of the Day• Tie the knot…… and leave it at God’s WillHadithEarly Warning Systems 2
  3. 3. TermsAdaptationActions taken to help communities and ecosystems cope withchanging climate conditionsCapacity buildingProcess of developing the technical skills, institutional capability, andpersonnel.CycloneAn atmospheric closed circulation rotating counterclockwise in theNorthern Hemisphere and clockwise in the Southern Hemisphere.EarthquakesEarthquakes are due to a sudden release of stresses accumulatedaround the faults in the Earth’s crust. This energy is released throughseismic waves that travel from the origin zone, which cause the groundto shake. Severe earthquakes can affect buildings and populations.Early Warning Systems 3
  4. 4. TermsDeforestationThe direct human-induced conversion of forested land to non-forestedland.DroughtsA period of abnormally dry weather sufficiently prolonged for the lackof water to cause serious hydrologic imbalance in the affected area.False AlarmIn the context of Early Warning Systems, a false alarm is defined as thesituation in which an alarm is activated when it should not have been.FloodsAn overflow of water onto normally dry land. Floods are oftentriggered by severe storms, tropical cyclones, and tornadoes.Early Warning Systems 4
  5. 5. TermsMissed AlarmIn the context of Early Warning Systems, a missed alarm is defined asthe situation in which an alarm is not activated when it should havebeen.MitigationThe lessening or limitation of the adverse impacts of hazards andrelated disasters.TsunamiA tsunami is a series of ocean waves generated by suddendisplacements in the sea floor, landslides, or volcanic activity.Volcanic eruptionsVolcanic eruptions may be mild, releasing steam and gases or lavaflows, or they can be violent explosions that release ashes and gasesinto the atmosphere.Early Warning Systems 5
  6. 6. The Hyogo Framework for ActionThe Hyogo Framework for Action (ISDR 2005), which wasadopted by the World Conference on Disaster Reduction inHyogo, Japan in 2005, identified five priority areas:1. Ensure that disaster risk reduction (DRR) is a national andlocal priority with a strong institution basis forimplementation;2. Identify, assess and monitor disaster risks and enhanceearly warning;3. Better knowledge management for building a culture ofsafety;4. Reducing the underlying risk factors; and5. Enhance preparedness for an effective responseEarly Warning Systems 6
  7. 7. MonitoringEarly Warning Systems 7
  8. 8. Earth ObservationEarth Observation, throughmeasuring and monitoring,provides an insight andunderstanding into Earth’scomplex processes andchanges. EO includemeasurements that can bemade directly or by sensors in-situ or remotely (i.e. satelliteremote sensing, aerial surveys,land or ocean-basedmonitoring systems) to providekey information to models orother tools to support decisionmaking processes.Early Warning Systems 8
  9. 9. Early Warning SystemThe set of capacities neededto generate and disseminatetimely and meaningfulwarning information toenable individuals,communities andorganizations threatened bya hazard to prepare and toact appropriately and insufficient time to reduce thepossibility of harm or loss.Early Warning Systems 9
  10. 10. Effective Early Warning Systems• extending the lead time ofwarnings• improving the accuracy ofwarnings• greater demand for probabilisticforecasts• better communication anddissemination of warnings• using new techniques to alert thepublic• targeting of the warning servicesto relevant and specific users(right information to right peopleat right time and right place)• warning messages areunderstood and the appropriateaction taken in response.Early Warning Systems 10

  23. 23. Japan’s Early Warning System• Japan invested in public alert systemafter 1995, 6.9 Kobe earthquake• Seven years and $500 million later,Japan unveiled worlds first earlywarning network.• The Japanese got their big test inMarch when a massive quake hit offthe northeast coast and spawned atsunami.• A public emergency announcementwas sent out eight seconds aftersensors detected the first inkling ofthe quake, interrupting regular TVand radio programming, and buzzingcell phones.• Millions received 5 to 40seconds of warningdepending on how far theywere from the epicenter.Tokyo — about 230 milesaway — got about 10 to 30seconds of notice beforehigh-rises swayed.A dozen trains werestopped in their trackswithout derailing.Japanese early warningsystem saved thousands oflives.Early Warning Systems 23

  34. 34. Famine in Africa• The crisis had been predictedover a year before, and manydedicated professionals did asmuch as they could to persuadetheir agencies and others torespond in order to prevent theworst of the crisis, but too littlewas done too late.• First things first. The mostfundamental duty of anygovernment is to provide itscitizens with basic protectionfrom physical threat and extremedeprivation, whether from war,criminal violence, or naturaldisaster. Everything else shouldcome second.• The experience of Somalia is astark demonstration of thestrengths and limits of theinternational humanitariancommunity to mobilize for earlyaction based on early warninginformation.Early Warning Systems 34
