The core samples they discuss in the program, "Monster Quake, are we there yet," suggest there are quake clusters that occur every 300 hundred years
but there can be another 700-1000 years between clusters. There are 4-5 quakes per cluster, and the 1700 quake was #5 indicating the cluster may be
complete. However, in the clusters, the last quake is most often the biggest, as much as 3 times bigger than all the rest, and the last quake in this
cluster was not any bigger. So the question was, is the last quake still coming, which could be as much as 3 times bigger than the Japan quake, or is
the most recent cluster now complete, in which case we may be clear for hundreds of years.
Just google it and see for yourselves.
