Geography

The Spatial Distribution of Earthquakes Along Transform Plate Boundaries

Quick fact

Earthquakes at transform boundaries like the San Andreas Fault are typically shallow, occurring within the top 15–20 kilometers of the crust, because the plates slide past each other without subducting into the mantle.

Why this is interesting

You may know that earthquakes happen at plate boundaries, but why do they cluster in a thin line along some boundaries, while spreading over wide zones at others? What creates that pattern?
