Big Earthquakes Don’t Trigger Other Large Ones

Inside Science Buzzwords:

1. Earthquake  - the sudden release of energy from movement of the Earth's crust which releases seismic waves.
2. Seismic waves - waves of energy that travel through the Earth’s crust and on its surface.
3. Seismometer - an instrument that measures seismic waves.
4. Seismogram - a record of a seismic wave.
5. Earthquake magnitude - expressed by the Richter Magnitude scale (ranging from less than 2.0 to greater than 10.0), a measurement of the energy in an earthquake, obtained by calculating the amplitude (height) of seismic waves on a seismogram.
