When lightning strikes, it superheats the air around it and creates a shock wave that we hear as thunder. But thunder doesn’t just travel through the atmosphere to our ears.

When that energy reaches the ground, some of it is converted into seismic waves that ripple through the soil and rock beneath. The resulting vibrations are known as “thunderquakes.”

Until now, scientists haven’t understood these signals well enough to make practical use of them. Our team’s research shows that
