Sometimes the entire CSZ faultline ruptures (as shown in figure A below) creating a magnitude 9 earthquake. Other times, a smaller segment of the faultline ruptures, resulting in a magnitude 8.
The figures below, provided by Professor Goldfinger, show the earthquake ‘names’ (white lettering), which can be cross-referenced to the ages here.
Below the Segments have been separated to make them easier to see (larger).
