Answer to Question 1

P-waves are primary waves; they arrive first to a seismograph because they are the fastest. They are
compressional and can travel through solids, liquids, and gases. S-waves are secondary waves; they
arrive second to a seismograph. They are shear waves because they move the material perpendicular to
the direction of travel. S-waves can only travel through solids.



Answer to Question 2

Although the causes are not well understood, these earthquakes are likely caused by localized stresses
caused by the compression that most plates experience along their margins.
