Seismic Waves

Seismic Waves and Earthquakes

Energy release and problems they cause

When a rock is thrown in to pond , waves ripple out from where the rock lands.

When an earthquake happens waves of energy from the focus radiate out from the epicenter of the earthquake.
Unlike the pond the waves travel in all direction from the epiccenter

Waves and eathquakes

Dropdown

When a rock hits the surface of the water, the waves move ​

Select answer

From the epicenter.

Multiple Choice

When an earthquake happens the energy from the Focus move out how from the epicenter?

• Horizontaly

• Vertically

• All Directions

• Angularly

An earthquake occurs when there is a sudden release of energy in the Earth's crust.

The release of energy creates
Seismic Waves.
These are waves of energy that travel through the Earth, causing earthquakes

The energy moves in the form of waves, similar to how ripples move across a pond when a stone is thrown into it.

Seismic waves

Multiple Choice

What is a seismic wave?

• Waves of energy from the the focus, the travel in all directions through the earth.

• Seismic waves are a type of sound wave.
• Seismic waves are only found in the atmosphere.
• Seismic waves are caused by volcanic eruptions.

Waves are part of everyday life.
Light waves allow us to see.
Sound waves allow us to hear.
Infrared Waves allow heating
Seismic waves carry energy from place to place.

There are three main types of seismic waves
primary (P) waves
secondary (S) waves
surface waves

Infrared wave

Sound Wave

• Light wave

• Seismic Wave

• Infrared wave

• Sound Wave

• P wave.

• Moves the fastest

• 3 Miles per second | 5km/sec

• First waves to reach any location from an earthquake.

• Waves travel through the earth.

• Can travel through solid, liquids and gasses.

• Cause material they pass through are slightly pulled and pushed apart

• Can cause some damage.

Multiple Choice

What is a P wave?

• The first wave that arrives at a location during an earthquake.

• A P wave is a type of sound wave.
• A P wave is a type of electromagnetic wave.
• A P wave is a type of ocean wave.

Drag and Drop

P waves cause a ​

• S waves

• Travel slower than P waves.

  • Half as fast. (1.5 mi/sec)

• Second wave to reach any location from an earthquake.

• Move through the earth interior.

• Can only travel through solids ( earth).

  • Cannot travel through Liquids and gasses

• Cause material moved through are in a shaken side to side or up and down.

• They can cause some damage.

Secondary wave

Multiple Choice

Witch type of wave arrives first during an earthquake to any location?

• P-waves (Primary waves)
• S-waves (Secondary waves)
• L-waves (Love waves)
• T-waves (Tertiary waves)

Multiple Choice

Witch type of wave arrives second during an earthquake to any location?

• P-wave
• T-wave
• L-wave
• S-wave

half as fast

twice as fast

at the same speed

• Travels the slowest.

• The last wave to reach any location from an earthquake, affecting a larger area and causing longer shaking.

• Move along the surface of the earth.

• Cause material they pass through to move roll up and down or side to side.

• They can MOST some damage.

• Surface waves can cause sway and shake, leading to structural damage and collapse during an earthquake.

Surface wave

Multiple Choice

What is surface wave?

• Surface waves propagate through the core of the Earth
• Surface waves travel faster than light waves
• Surface waves are a type of electromagnetic wave
• Surface waves are the slowest seismic wave the move along the surface of the earth.
