Answer 2

The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Fires are probably the single most important secondary effect of earthquakes.

Ground Shaking

Below is an image of the Cypress viaduct which was part of Interstate 880 in Oakland, CA. The upper level of the two-level structure has collapsed onto the lower level as a result of failure of the support columns. The columns failed partially in response to ground shaking from the 17 October 1989 Loma Prieta earthquake amplified by loose sediments near the Oakland waterfront. 41 people were killed in the collapse.
