What’s interesting is that geologists say you won't notice any differences. The moment magnitude of these vibrations in March must have caused unthinkable strain energy discharged from the fault surface (Chapter 11, pages 315- 316). This earthquake was one of the most important and devastating in history, as it almost surpassed the strongest earthquake of all time, which was the 1960 Chilean earthquake with a 9.5 moment magnitude (Chapter 11, page 315). This earthquake was destined to make some changes to the Earth’s rotation. The research scientist Richard Gross used United States Geological Survey estimate for how the fault responsible for the earthquake slipped. This amount of slip on the fault combined with the strength of the faulted rock and the area of the fault surface that slipped are the elements that are...
