Epicentre and nearby recent earthquakes
The highlighted circle is this earthquake. Smaller circles are other events recorded nearby in the last 30 days.
What the shaking was like
Shallow earthquakes release their energy close to the surface, so they are felt more strongly nearby than a deeper earthquake of the same magnitude.
Estimated instrumental shaking I (Not felt): Not felt except by a very few under especially favourable conditions.
