The Indonesian Earthquake
This map shows the location of the earthquake, which is near Indonesia. (Source for all map graphics: http://www.usgs.gov.)
The Indonesian Earthquake
This map shows the location of the epicenter relative to population density.
The Indonesian Earthquake
A side-by-side comparison of the two epicenters shows that the 2004 earthquake was closer to land. Because it was a much stronger earthquake, its proximity also meant the potential for more damage. Note that both earthquakes occurred under water, which is what causes tsunamis.
The Indonesian Earthquake
This graph compares the magnitude of the two earthquakes. The close numerical values of the two magnitudes (8.6 vs. 9.1) suggests comparably strong earthquakes. But magnitude uses a logarithmic scale.
The Indonesian Earthquake
This graph compares the intensity of each of earthquake. Here you can see the dramatic difference in intensity.
The Indonesian Earthquake
The intensity of an earthquake is proportional to an exponential expression of base 10 whose exponent is the size of the earthquake magnitude. For simplicity, let’s assume this proportion is an equation.
