What this means
This was a minor earthquake of magnitude 3.4. Often felt by people near the epicenter but rarely causes damage.
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.
