Light — felt locally, damage unlikely. This was a magnitude 4.8 earthquake — classed as light. Magnitude 4.0–4.9 earthquakes are widely felt nearby, can rattle windows and objects on shelves, and occasionally cause minor damage to weak structures.
At 10.0 km this is a shallow earthquake. Shallow quakes release their energy close to the surface, so shaking is usually stronger and more damaging than a deeper quake of the same magnitude — but it is felt over a smaller area.
Nearest major city: 385 km NW of Sacramento, United States.
