P and S waves
Two kinds of seismic waves, how each one moves the ground, and how the gap between them tells us how far away an earthquake is. Real records from the CHARNET network.
How to find the epicentre
Three stations, three circles, one point: how we located the earthquake of 6 November 2026 in north-western Iran.
What is magnitude?
Magnitude and intensity, why each step means 10 times bigger waves and about 32 times more energy, and how big the earthquakes our stations recorded really were.
