What this means
This was a light earthquake of magnitude 4.6. Usually causes noticeable shaking and rattling of indoor objects, but significant damage is unlikely.
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.
