Speaker Notes Good morning/afternoon everyone. Today, we will delve into the devastating 2004 Indian Ocean tsunami and explore how we can strengthen disaster response efforts for similar events in the future. Slide 2: The Disaster (Image)

• A powerful 9.3 magnitude earthquake struck the undersea Sumatra-Andaman Plate Boundary.
• The earthquake triggered a series of massive tsunamis that devastated coastlines in Indonesia, Sri Lanka, India, Thailand, and other countries bordering the Indian Ocean.

The earthquake's epicenter lay off the western coast of Sumatra, Indonesia, registering a staggering 9.3 on the Richter scale, making it one of the most powerful earthquakes ever recorded. The resulting tsunamis traveled at incredible speeds, reaching coastlines within minutes and wreaking catastrophic destruction. Slide 3: Risk Factors (Image)

• Lack of a comprehensive tsunami warning system in the Indian Ocean region.
• Densely populated coastal areas with limited evacuation plans.
• Inadequate public awareness about tsunamis and evacuation procedures.
• Limited infrastructure to withstand the impact of powerful tsunamis.

  download photo_prints Speaker Notes Several critical risk factors amplified the devastation caused by the 2004 tsunami. The Indian Ocean lacked a robust tsunami warning system, hindering timely evacuation efforts. Coastlines were densely populated, with many communities residing in low-lying areas directly exposed to the tsunami's wrath. Widespread public unawareness about tsunamis and evacuation procedures further hampered preparedness. Additionally, coastal infrastructure was insufficient to withstand the immense force of the waves. Slide 4: Consequences (Image)

• Over 230,000 fatalities across affected countries.
• Widespread destruction of homes, businesses, and infrastructure.
• Displacement of millions due to loss of homes and livelihoods.
• Long-term environmental damage and economic disruption.

Speaker Notes The consequences of the 2004 tsunami were horrific. Over 230,000 lives were tragically lost across the affected nations. Entire communities were decimated, with homes, businesses, and infrastructure obliterated by the relentless waves. Millions faced displacement, having lost their homes and livelihoods. The tsunami also caused lasting environmental damage, contaminating water sources and disrupting ecosystems. The economic impact was severe, hindering recovery efforts for years to come. Slide 5: Existing Disaster Response Measures (Image)

• Many countries have established early warning systems for other natural disasters like cyclones.
• Some local communities have developed informal warning systems based on natural signs.
• Stockpiling of emergency supplies in disaster-prone areas.

  download photo_prints Speaker Notes Prior to the 2004 tsunami, disaster response measures in the region primarily focused on other natural hazards like cyclones. Some coastal communities had developed rudimentary warning systems based on natural signs like receding water levels. Additionally, stockpiling of emergency supplies was practiced in some areas. However, these measures proved inadequate in the face of a large-scale tsunami. Slide 6: Identified Weaknesses in Tsunami Response (Image)

• Absence of a regional tsunami warning system in the Indian Ocean.
• Limited public education and awareness about tsunamis and evacuation procedures.
• Inadequate evacuation plans and infrastructure for coastal communities.
• Lack of international collaboration and coordination for disaster response.

Speaker Notes The 2004 tsunami exposed significant weaknesses in disaster response capabilities. The lack of a regional tsunami warning system was a critical gap. Public education and awareness about tsunamis and evacuation procedures were sorely lacking. Many coastal communities lacked proper evacuation plans and infrastructure to facilitate a
