Why depth matters

Intermediate-depth quakes are felt across a wider area but usually cause less surface damage.

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.
