Measuring
Richter scale
10 logarithmic scale
Amplitude of seismic waves
S waves- slow, through liquid, destructive
P waves - small, coiled

Only scale that’s accurate over 8
Measures the effects of the earthquake
Modified mercalli scale
Personal experience
Measures damage
Where they occur
Plate boundaries
Fault lines
Is caused by plates getting stuck
Caused by a sudden release of energy
Speed of onset is crucial as earthquakes come with little warning
