As if a massive drought wasn’t bad enough, many of California’s biggest cities are supplied by aqueducts that are hundreds of miles long, that are then fed into old water mains that are due for replacement. The aqueducts travel so far that they are likely to cross fault lines, and could therefore be damaged in a quake. The iron pipes under the streets are under threat of damage as well. Kobe, Japan was in a similar situation when its quake hit. It took three months to complete the necessary repairs. The current drought heightens the threat because there would be less local ground water and rain water for individuals to collect themselves. Temporary migrations might be necessary, and billions of dollars, of course.
