The second type of body wave is the S wave or secondary wave, and are easy to remember because they’re the second wave to arrive after an earthquake. An S wave is about 1.7 times slower than a P wave. The biggest difference is that S waves can’t move through liquids. Because S waves only move through solids, seismologists were led to ...Before an earthquake. Make sure you and your household are earthquake-ready: Secure heavy furniture and appliances – More than half of the injuries associated with the 1994 Northridge earthquake were caused by toppling objects.
