What does an M5.1 "Moderate" reading actually indicate?
The USGS classifies M5.1 as "Moderate" on its Earthquake Hazards Program scale. Events in this range are often felt near the epicenter and can cause minor damage to vulnerable structures, though widespread damage is uncommon.
Is this earthquake stronger or weaker than others in the archive?

Was Yudomari likely to feel this earthquake?
This event was centered 101 km S of Yudomari. Shaking intensity falls off sharply with distance from the epicenter and depends on depth and local geology, so check the USGS "Did You Feel It?" report for this event for real felt-shaking data rather than assuming from magnitude and distance alone.
