Earthquakes 1

The epicenter of an earthquake is

• The point below the surface where rock begins to break and the first motion occurs
• The seismic station closest to the earthquake
• The place where the greatest damage occurs
• The point on the surface directly above the focus

Which travels fastest, always being the first detected by seismic stations?

• P waves
• S waves

An instrument that detects and measures earthquakes is a 

• seismogram
• focus seismic map
• focus
• seismograph 

Most earthquakes happen along the _________________. 

• coast
• faults
• desert
• directions

Identify the type of boundary associated with this fault:

• Convergent

• Divergent

• Transform

Earthquakes under the water can cause _________________________________.

• tornadoes
• tsunamis
• lightening
• hailstorms

P-wave 

• The center of a earthquake. 
• Also know as shear or secondary wave. 
• Always the first to arrive;  seismic wave that causes particles of rock to move in back-and-forth direction
• Hilbert
