    Study Notes

    Earthquakes

    • Earthquake is the shaking of the ground caused by the movement of crustal plates
    • Plates moving towards or away from each other cause nearby rocks to break and slide, releasing waves of energy and triggering an earthquake
    • Motion of the ground during an earthquake is measured by a seismograph

    Types of Earthquakes

    • Tectonic earthquake: occurs when there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane
    • Volcanic earthquake or tremor: a long-lasting rhythmic signal associated with magma in motion, can last for minutes or days

    Volcanic Earthquake

    • Happens with a strong volcanic eruption
    • High temperature and pressure in the melting of rocks producing magma
    • Molten rock inside the chamber is forcefully driven out by intense heat and pressure, causing a volcanic eruption

    Tectonic Earthquake

    • Caused by the movement of the Earth's crust
    • Can occur above ground or beneath the ocean

    Preparing for a Volcanic Eruption

    • Have an emergency supply kit at home, containing flashlights, batteries, first-aid materials, supplies of bottled water, nonperishable food, and medicines
    • Discuss and plan an emergency preparedness plan for volcanic eruptions, including where to go during an eruption and how to apply first-aid treatments
    • Always listen to the radio or watch for updates on the volcanic eruption
