Significant earthquake
Magnitude 5.3 – SERBIA

Two people killed and several injured at Kraljevo

From the EQ stats page

Magnitude vs. Ground Motion and Energy

Magnitude Change
Ground Motion Change
(Displacement)
Energy Change
1.0
10.0 times
about 32 times
0.5
3.2 times
about 5.5 times
0.3
2.0 times
about 3 times
0.1
1.3 times
about 1.4 times
This table shows that a magnitude 7.2 earthquake produces 10 times more ground motion than a magnitude 6.2 earthquake, but it releases about 32 times more energy. The energy release best indicates the destructive power of an earthquake. See: How much bigger is a magnitude 8.7 earthquake than a magnitude 5.8 earthquake?

HW: How much bigger? Calculator
Lets do three well known recent earthquakes
1. Haiti M7.0

2. The recent Indonesia one that produces a tsunami M7.8

3. Chile M8.8
