Relevance for Individual and Community Preparedness

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.

  • Myth: Tattooed response preparedness time can prevent catastrophe. Reality, proper safety measures still impact homes beyond structural reinforcement.
  • P-waves

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

    Take the First Step in Understanding and Preparation

    Tsunamis occur when a massive earthquake causes a displacement of the ocean's water, resulting in a high-speed wave.

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

  • Understanding local seismicity is essential for proper preparedness and evacuation strategies.
  • 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.

    These smaller shocks occur as the Earth's crust continues to adjust following an initial earthquake and can last for months or even years.

    Debunking Common Misconceptions About Earthquakes

    Movement between plates results in potential earthquakes, released energy generating destructive waves.

  • There's no guaranteed earthquake prediction method.
