Seismic hazard zone (liquefaction zone and landslide zone)

[James Z.]

Hi, we are reviewing disclosures of two small multi-family (2-4 units) homes located in the SF bay area. Looks that both of them are close to Seismic Hazard Zone (liquefaction zone and/or landslide zone), and one of them is very close to the zone. We'd like to know: does either the liquefaction zone or landslide zone expands in the future? We concern if either of them expand, it may get to one of both of the homes. Also, how liquefaction zone or landslide zone affects or damages properties, and if there are effective ways to handle them? All replies are very much appreciated!
