Seismologists are studying fault zones in and around New Zealand to better understand how megathrust earthquakes happen.
Ludger Mintrop designed equipment to test geophysical theories of his teacher, the German geoscientists Emil Weichert, and incidentally founded the geophysical field of seismic reflection profiling.
Also he punched the Earth. Real hard.
Have you ever wondered how seismologists locate earthquakes and figure out their magnitude? And, wherever the quake, what controls how much shaking you feel?
