Understanding Earthquakes

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

Earthquake Risk and Reality

  • At risk individuals, law enforcement, government agencies, civil engineers, and insurance providers will benefit from accessible disaster resources.
  • Relevance for Individual and Community Preparedness

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

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

      What is a tsunami?

    • Understanding local seismicity is essential for proper preparedness and evacuation strategies.
      • There's no guaranteed earthquake prediction method.
      • Seismic waves travel through the Earth's layers, causing damage based on their speed and type.

        P-waves

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

      • Certain areas are particularly susceptible to earthquakes due to fault lines.
      • Movement between plates results in potential earthquakes, released energy generating destructive waves.

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

        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.

        What is the Earth's crust?

        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.
