What is the process called that uses data from three seismic stations to locate an earthquake's epicenter?

• Seismography

• Epicentral mapping

• Triangulation

• Wave analysis

What is a key difference between P-waves and S-waves?

• S-waves can travel through liquids, while P-waves cannot.

• S-waves are compressional waves, while P-waves are shear waves.

• P-waves are slower than S-waves.

• P-waves travel through solid, liquid, and gas, while S-waves only travel through solids.
