Quakeling — How Shaking Travels Fault Crack Cavern

Hi!

I'm Quakeling.

Welcome to Fault Crack Cavern!

Will you help me investigate how shaking travels?

The Grumblies have mixed up our clues.

Let's check the evidence!

Earthquake energy travels through Earth as seismic waves.

Material vibrates as a wave passes;

every rock does not travel all the way from the

source to a distant town.

What travels outward during an earthquake?

  • A. Only air from volcanoes
  • B. Seismic energy
  • C. The entire source rock to each town

The answer is B: Seismic energy

Earthquake energy travels through Earth as seismic waves.

Material vibrates as a wave passes;

every rock does not travel all the way from the

source to a distant town.

That clue helps us make sense of this place.

Shaking can differ with distance, ground and other conditions.

The underground starting area and the point on the surface

above it are not the same place.

Why can distant sensors respond later?

  • A. Waves take time to travel
  • B. They create separate earthquakes automatically
  • C. Distant sensors destroy all waves

The answer is A: Waves take time to travel

Earthquake energy travels through Earth as seismic waves.

Material vibrates as a wave passes;

every rock does not travel all the way from the

source to a distant town.

Hmm...

how does that connect to our first clue?

Our sensor record detects shaking first near the source

and later farther away.

The time order supports traveling energy, not every sensor starting the earthquake.

Must every location shake equally?

  • A. Yes, distance never matters
  • B. Only oceans can shake
  • C. No, conditions differ

The answer is C: No, conditions differ

Shaking can differ with distance, ground and other conditions.

The underground starting area and the point on the surface

above it are not the same place.

Nice investigating!
