What this means
This was a moderate earthquake of magnitude 5.6. Can damage poorly built structures near the epicenter, while well-designed buildings usually suffer slight damage at most. Roughly 1,300 earthquakes of this size occur worldwide each year.
Magnitude measures the energy released at the source. How strongly the ground shook at any particular place depends on distance from the epicenter, the depth of the quake, local geology and building construction, so the same magnitude can be harmless in one place and damaging in another. First magnitudes are preliminary and are often revised by a few tenths as more stations report.
