Earthquakes have occurred since it's creation and the the island is still there. Without looking at the development plans, I'm sure that part of the plan would be to shore up the ground. There are many places built on landfill(ie. much of Boston).
The island was created in 1937. The strongest earthquake since that time was a 7.7 in 1952.

I'm sure there are people here who better understand logarithmic scales than I do and can go over the difference between a 7.7 and an 8.5+, and the Bay Area is overdue for a big one right now.
