  • Myth: Tattooed response preparedness time can prevent catastrophe. Reality, proper safety measures still impact homes beyond structural reinforcement.
  • Seismic waves travel through the Earth's layers, causing damage based on their speed and type.

    Earthquake Waves

  • There's no guaranteed earthquake prediction method.
  • These smaller shocks occur as the Earth's crust continues to adjust following an initial earthquake and can last for months or even years.

    Primary waves (P-waves), travels at high speeds, up to 6 kph.

    What causes aftershocks?

    The recent trend of disaster awareness is attributed to an increase in natural disasters and awareness campaigns, including stories about evolving earthquake resilience and areas for improvement.

    The 1906 San Francisco earthquake is still remembered as one of the most devastating natural disasters in US history. In the aftermath of the quake, it's estimated that over 3,000 people lost their lives. As discussions around disaster preparedness and building resilience grow, this event's significance takes center stage.

        Debunking Common Misconceptions About Earthquakes

      • Myth: Building height and location reduce the impact of earthquakes. Reality, *both can significantly impact damage and displacement.
        • Movement between plates results in potential earthquakes, released energy generating destructive waves.

        • Certain areas are particularly susceptible to earthquakes due to fault lines.
        • Tsunamis occur when a massive earthquake causes a displacement of the ocean's water, resulting in a high-speed wave.

        The Earth's crust is the outermost solid layer, comprising continental and oceanic plates that move continually.

        (S-waves) travel slower than P-waves and move through the Earth's interior at approximately 87% its P-wave speed.

        An earthquake occurs when there's a sudden release of energy in the Earth's crust, typically as a result of tectonic plate movement. This release creates seismic waves that can cause widespread destruction.
