Seismology
Seismology is the study of earthquakes and how the ground shakes and moves.
Think of it this way
Tap a table and feel it shake. Earth shakes the same way during quakes. Scientists study those shakes. The waves travel through the ground and tell us what is deep inside.
Explaining seismology by grade level
The ground under your feet seems still, but it can shake and move. Scientists look at old records of earthquakes to find patterns. They use those patterns to guess when the ground might shake again. This helps people stay safe.
