Why depth matters

Shallow quakes release energy near the surface — shaking is felt more strongly and damage potential is higher.

Depth classes per USGS

Official USGS aftershock forecast

Probability of at least one aftershock at or above the specified magnitude during the entire stated time window. This does not predict an individual earthquake.
