Epicenter
Which scale characterizes the severity of ground shaking at a specific location during an earthquake?
Mercalli Scale
What does a seismograph measure in relation to earthquakes?
Energy waves of the Earth
What type of fault is gradually accumulating energy as rocks bend until they suddenly snap, releasing the stored energy?
Active Fault
At what earthquake magnitude level does slight damage to well-designed buildings occur?
Under 6.0
Which earthquake scale measures the energy released during an earthquake?
Richter Scale
What is the difference between a focus and an epicenter in relation to earthquakes?
The focus is the point where the earthquake originates inside the Earth, while the epicenter is the point on the Earth's surface directly above the focus.
