"I think it's Richter 9 that's expected, and that it's roughly every 500 years. We're not overdue, but we're in the timeframe now."

This article is the first I've seen with such a long period. All of the "Discovery" documentaries I've seen say 300-350 years.

Maybe 500 is new data--or wishful thinking.
