Seismology & Earthquakes
📋 What it is
Seismology is the science of measuring earthquakes — locating them, sizing them, and improving safety.
🗣️ Coach says
Seismologists use instruments (seismometers) to detect and measure earthquakes. By timing when waves arrive at different stations, they pinpoint the quake’s location and depth, and measure its magnitude. This science drives early-warning systems and safer building design in quake zones.
🧠 Memory hook
Seismology = measure quakes with seismometers → locate, size, and warn. Drives safer buildings.

What did the continental plate say to the oceanic plate?
"You're going down!" — and it was right, because oceanic plates subduct!
😲 Whoa!
Earthquake early-warning systems can give people several precious seconds of alert — because the warning signal (radio) travels faster than the destructive seismic waves.
✅ Quick check: How can an early-warning system alert people before a quake’s shaking arrives?
Say your answer out loud first — then reveal.
It detects the first waves and sends an electronic alert faster than the slower, destructive seismic waves travel.
Electronic signals outrun the damaging seismic waves.
🧪 Try it! (2 minutes)
Tap a table and have someone far along it feel the delay — waves take time to travel, like seismic waves.
