Using thunderquakes to X‑ray Earth – a new study shows urban seismology in action
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.”

Thunderquake raypath diagram. Raypath schematic of thunderquake generation. Direct acoustic waves from along the thunderbolt (T1 and T2) couple into the ground and environment, creating propagating waves and surface waves. The summation of all these waves constitutes the thunderquake wavefield observed by DAS. (CREDIT: Tieyuan Zhu et al, Science Advances)

Very interesting, ta Tau. I hadn’t heard of thunderquakes before.
