About earthquakes in including Grays Reef National Marine Sanctuary
Most earthquakes are too small to feel. The USGS reports millions of quakes a year worldwide, and the vast majority are below magnitude 2.5. A page showing no recent activity usually means no notable quakes, not that nothing is being measured.
Magnitude is a measure of the energy released at the source; shaking you actually feel also depends on depth and how far you are from the epicenter. A shallow magnitude 4 nearby can feel stronger than a deep magnitude 5 far away.
