How should a magnitude 5.5 ("Moderate") event be understood? ▾
The USGS classifies M5.5 as "Moderate" on its Earthquake Hazards Program scale. Events in this range are felt over a wide area and can cause significant damage near the epicenter, particularly to older or unreinforced buildings.

Was Pelabuhanratu likely to feel this earthquake? ▾
This event was centered 187 km SSW of Pelabuhanratu. 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.
