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.

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

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.

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

  • Myth: Building height and location reduce the impact of earthquakes. Reality, *both can significantly impact damage and displacement.
  • Myth: Tattooed response preparedness time can prevent catastrophe. Reality, proper safety measures still impact homes beyond structural reinforcement.
  • (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.
  • Discuss and prepare emergency response plans
  • There's no guaranteed earthquake prediction method.

    Earthquake Waves

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

Understanding Earthquakes

  • At risk individuals, law enforcement, government agencies, civil engineers, and insurance providers will benefit from accessible disaster resources.
  • These smaller shocks occur as the Earth's crust continues to adjust following an initial earthquake and can last for months or even years.

    Seismic waves travel through the Earth's layers, causing damage based on their speed and type.

  • Develop knowledge through educational resources
  • 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.
