Unlike events in California or Japan, which occur at plate boundaries, intracratonic earthquakes happen within the stable interior of a continent. They are much rarer but can be surprisingly damaging because the crust in these areas is often rigid and can transmit seismic waves over vast distances. 2. The Impact of the 2007 Event
This event is particularly notable in seismology because it was an , meaning it happened in the middle of a tectonic plate—an area usually considered geologically stable. (4.9 MB)
The epicenter was near Itacarambi, in the São Francisco Craton area. Unlike events in California or Japan, which occur
