Explanations: answer key for all 10 questions

Q1: What causes most earthquakes?
Answer: Sudden movement along faults
Stress builds up and is released.
Q2: What is the point on the surface above an earthquake's origin called?
Answer: Epicenter
The underground origin is the focus or hypocenter.
Q3: Which seismic waves arrive first?
Answer: P waves
They are compressional and travel fastest.
Q4: What instrument records earthquakes?
Answer: Seismograph
It traces ground motion.
Q5: Who developed a famous earthquake magnitude scale in 1935?
Answer: Charles Richter
Today scientists use the moment magnitude scale.
Q6: How much more energy does a magnitude 7 release than a magnitude 6?
Answer: About 32 times
Each step is about 32 times more energy.
Q7: What was the strongest earthquake ever recorded?
Answer: 1960 Chile earthquake
It measured about magnitude 9.5.
Q8: What can a large undersea earthquake cause?
Answer: A tsunami
The 2004 Indian Ocean tsunami was devastating.
Q9: What magnitude was the 2011 Tōhoku earthquake in Japan?
Answer: About 9.0
It caused the Fukushima nuclear accident.
Q10: What is the recommended action during an earthquake indoors?
Answer: Drop, cover and hold on
Protect yourself under sturdy furniture.

Earthquakes Quiz – When the Ground Shakes

Earthquakes happen when rocks along faults suddenly slip, releasing built-up stress as seismic waves. Most occur along plate boundaries, especially around the Pacific Ring of Fire, but they can happen almost anywhere.

Seismographs record the waves, letting scientists locate earthquakes and measure their size. The moment magnitude scale is logarithmic, so each whole number means about 32 times more energy. The 1960 Chile earthquake, around magnitude 9.5, is the strongest ever recorded.

Earthquakes can trigger tsunamis, landslides and fires. Scientists cannot yet predict them precisely, but building codes, early warning systems and drills like drop, cover and hold on save many lives.
