K. Aki

K. Aki is a renowned seismologist known for developing key theories about earthquakes. His most famous contribution is the concept of using the frequency content of seismic waves—how quickly the waves vibrate—to estimate the size and energy of an earthquake, helping scientists understand the earthquake's power. Aki's work also emphasized that faults in the Earth's crust behave in predictable ways, which improves earthquake risk assessment. His research combines physics, geology, and engineering, making earthquake science more accurate and practical for engineering structures and public safety.
