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
At this depth the energy spreads out before it reaches the surface, so shaking is usually weaker but felt over a wider area.
Estimated instrumental shaking I (Not felt): Not felt except by a very few under especially favourable conditions.
