FINAL JEOPARDYSubject: Loma Prieta Earthquake
Why did San Francisco endure so much more damage in the Marina district than the city of San Jose which was 50 miles closer to the epicenter
Liquefaction – Marina district was built on land-fill, and therefore shook with much more force, because the land was so much more unstable
