Mission Statement • The Global Disaster Health Network is designed to translate the best possible scholarly information to educators worldwide.
Mission Statement • The Global Disaster Health Network is designed to translate the best possible scholarly information to educators worldwide. What are the Disaster Supercourse & JIT lecture?
. What is the Disaster Supercourse? What is a JIT lecture? http://www.pitt.edu/~super1
Lecture objectives • To provide the best possible scientific information about the Indonesia earthquake, 27 May 2006 • To teach how the science can help Indonesian to be prepared for primary & secondary prevention of consequences of earthquake
Lecture objectives • In this lecture you will find: • How the vulnerability conditions can change a natural hazard to a disaster?
What is the earthquake? The shaking of earth caused by waves moving on and below the earth's surface and causing: surface faulting, tremors vibration, liquefaction, landslides, aftershocks and/or tsunamis.
How earthquake happens? • It caused by a sudden slip on a FAULT. • Stresses in the earth's outer layer push sides of fault together. • Stress builds up & rocks slips suddenly, releasing energy in waves that travel through the earth's CRUST & cause the shaking that we Feel during an earthquake.
Earthquake Strength Measures I) Magnitude & II) Intensity I) Magnitude: • Definition:A measure of actual physical energy release at its source as estimated from instrumental observations. • Scale:Richter Scale • By Charles Richter, 1936 • Open-ended scale • The oldest & most widely used Noji 1997
Earthquake Strength Measures I) Magnitude & II) Intensity II) Intensity: • Definition:a measure of the felt or perceived effects of an earthquake rather than the strength of the earthquake itself. • Scale:Modified Mercalli (MM) scale • 12-point scale, ranges from barely perceptible earthquakes at MM I to near total destruction at MM XII
Magnitude versus Intensity • Magnitude refers to the force of the earthquake as a whole, while intensity refers to the effects of an earthquake at a particular site. • An earthquake can have just one magnitude, while intensity is usually strongest close to the epicenter & is weaker the farther a site is from the epicenter. • The intensity of an earthquake is more germane to its public health consequences than its magnitude.

Indonesia’s Health Statistics • Child mortality M/F (per 1000): 41/36 • Adult mortality M/F (per 1000): 239/200 • Total health expenditure per capita (Intl $, 2003): 113 • Total health expenditure as % of GDP (2003): 3,1

Indonesia Earthquake, 27 May 2006 • Time: 5/53/58 Local Time • Magnitude: 6.3 on Richter scale • Region: Java, Indonesia • Geolocation: 7.962°S, 110.458°E • Main Affected area:Yogyakarta , Java • Depth:10 km (6.2 miles) • Epicenter:37 km south of Yogyakarta 455 Km of Jakarta
Daerah Istimewa Yogyakarta (DIY) province • People of DIY only were worry about the eruption of Mount Merapi in the Northern part of City of Yogyakarta, they had never thought about earthquake over hundred years! • DIY has a special status in Republic of Indonesia, although in the Province level, the governor is always the descendant of the King, to honor the culture of Kingdom.
Indonesia Earthquake: Infrastructure Damage • Roads & Bridges: ~ 49 km • Destroyed Schools: 269 • Government Buildings: 302 • Religious Buildings:18,959 • Local Markets: 9 • Destroyed houses: 60,000
Damage Building and Housingin District of Klaten, Province of Central Java
Indonesia Earthquake: Damage to Health Facilities 01 June 2006
Damage to Health Facilities City of Yogyakarta of Province of DIY • 6 Public Health Centers (PHC) & 1 Sub PHC were severely damaged • 9 PHCs and 6 Sub PHCs were moderately damaged • 3 PHCs and 4 Sub PHCs were mildly damaged. District of Klaten of Province of Central Java • 2 PHCs and 8 Sub PHCs were destroyed • 7 PHCs and 25 Sub PHCs were severely damaged • 5 PHCs and 20 Sub PHCs were mildly damaged rusak ringan District of Bantul of Province of DIY • 15 PHCs, 1 District Health Office, 30 Sub PHCs and 46 Houses of Officers were severely damaged • 4 PHCs, 13 Sub PHCs and 21 Houses of Officers were moderately damaged • 7 PHCs, 1 District General Hospital of Bantul, 13 PHCs and 4 Houses of Officers were mildly damaged.

Indonesia Earthquake: Mortality distribution 31/05/2006
Indonesia Earthquake: Health Needs & Concerns • Shelters & tents • Medical Assistance • Lacks of Medical Staff & services • Bed sheets, mattresses • Clean Water & Food • Disease surveillance system
Some key points in relief operation: • Emergency Health Information System • Importance of right kind of donations (based on • right needs assessment) • Incident Command System (ICS) • Inter and Intra sectoral Coordination
Public Health Consequences of Earthquakes Pease see the following lectures: Part I. http://www.pitt.edu/~super1/lecture/lec13021/index.htm Part II. http://www.pitt.edu/~super1/lecture/lec13051/index.htm
Indonesia Earthquake: Economical Damage • Only for covering the 6 months relief needs: 103,389,500 US$ (UN Flash Appeal) How about the recovery & reconstruction of damaged infrastructures?
Indonesia Earthquake • Several decades of development wiped out in seconds in Yogyakarta & Java • How many percent of Indonesia GDP has been lost in the recent earthquake? • What do you think about spending this money on prevention? And absolutely without loosing the lives and injuries!
30 years continuous evolution in the practice of Crisis or Disaster Management • Civil defense • Emergency assistance • Disaster response and relief • Humanitarian assistance • Emergency management • Civil protection • Disaster mitigation and prevention • Disaster Risk Management Strategic shift from managing a disastrous event to more preventive and proactive approaches!!
What is Disaster risk reduction (disaster reduction or DRR)? • The conceptual framework of elements considered with the possibilities to minimize vulnerabilities and disaster risks throughout a society, to avoid (prevention) or to limit (mitigation and preparedness) the adverse impacts of hazards, within the broad context of sustainable development !
DRR Terminology: What is the Hazard? • A potentially damaging physical event, phenomenon or human activity that may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation.
DRR Terminology: What is the Vulnerability? • The conditions determined by physical, social, economic, and environmentalfactors or processes, which increase the susceptibility of a community to the impact of hazards. • Vulnerable Yogyakarta , Java: • Unprepared people, society • Unprepared institutions • Non-resistant building • High-density population • etc.
What is Risk? • The probability of harmful consequences, or expected losses (deaths, injuries, property, livelihoods, economic activity disrupted or environment damaged) resulting from interactions between natural or human-induced hazards & vulnerable conditions. • Risk = Hazards x Vulnerability
What is a Disaster ? • A serious disruption of the functioning of a community or a society causing widespread human, material, economic or environmental losses which exceed the ability of the affected community or society to cope using its own resources.
What is a Disaster? • A disaster is a function of the risk process. • It results from the combination of hazards, conditions of vulnerability and insufficient capacity or measures to reduce the potential negative consequences of risk.
Indonesian earthquake: Risk model • Maybe DIY & Java communities were not able to modify the hazard part of the earthquake risk model, and predict it precisely, BUT they could assess their vulnerability conditions and reduced them! • This has been the same experience in Bam & Kashmir!
Main Lesson Learned So, an earthquake measuring 6.3 on the Richter scale is not equal to a disaster. It is just movement of the earth crust. Our vulnerability has changed it to a disaster!!
Just-in-Time Education Let’s teach the communities right now ! Risk awareness & Knowledge development including education, training, research and information are of the important fields of action for Disaster Risk Reduction!
Information …. • People need information as much as water, food, medicine or shelter. • Information can save lives, livelihoods & resources. • Lack of information can make people victims of disaster. World Disaster Report 2005 – IFRC/RCS
