MAGNITUDE KINEME

Focus

Location of initial slip on the fault, where the earthquake origins

Epicenter

Spot on Earth's surface directly above the focus

Body wave

• Travel through the interior of the Earth.

• Higher frequency than surface waves.

Primary Waves

• fastest kind of seismic waves the first to arrive at a seismic station

• move through solid gas liquid

• compressional or longitudinal waves

• pushing and pulling

• Parallel

Secondary Waves

• These are waves that arrive second

• Travel through solid rocks

• up and down, or side-to-side

• perpendicular to the direction that the waves are traveling in.

• transverse or shear waves

Surface Waves

• Travel only through the crust.

• lower frequency than body wave

• Arrives LAST in seismic wave

• responsible for destruction

Rayleigh wave

• Travels like an ocean wave

• Slowest wave

• Travels alog the surface producing a rolling motion

Love wave

• Exhibit horizontal motion

• Travels the fastest

• Side to side

• Travel through LITHOSPHERE

Seismograph

Detect and record seismic waves

Intensity

Is the strength of the earthquake perceive and felt by people in a certain locality

higher generally near the epicenter

Magnitude

Energy released by an earthquake at the focus
