解題步驟

  1. Understand the question
    1. ccc cause and effect a news bulletin reports a powerful earthquake 200 kilometers off the coast of california. hours later, theres no sign of any tsunami anywhere on the west coast. why not?
  2. Brief Explanations

    Tsunamis are typically triggered by underwater earthquakes that cause large vertical displacement of the seafloor (pushing or pulling large volumes of water). If the California offshore earthquake was a strike-slip earthquake (where tectonic plates slide horizontally past each other), it would not produce significant vertical seafloor movement. Without this vertical shift, no large, displaced water column is created to generate a tsunami that reaches the coast.

  3. Final answer

    The earthquake was likely a strike-slip type (horizontal plate movement) that did not cause significant vertical displacement of the seafloor. Tsunamis require large vertical shifts of the ocean floor to displace enough water to form a wave that reaches the coast, so this horizontal movement would not generate a detectable tsunami on the West Coast.
