Science

Magnitude, depth and shaking: why two earthquakes of the same size can feel completely different

Magnitude is only one part of the story. Depth, distance, local ground conditions and building vulnerability help explain why shaking can differ so much from one earthquake to another.

Earthquake-resistant building standards: what safer structures are actually designed to do

Earthquake-resistant design is not about making buildings immovable. It is about controlling forces, deformation and failure so people have a much better chance of staying safe.

Earthquake early warning: how a few seconds can help, and why it is not a prediction

Early-warning systems detect an earthquake after it starts and try to send an alert before the strongest shaking arrives. The difference between warning and prediction matters.
