A bill has been introduced in the California legislature this week to improve earthquake safety.  Senate bill 1155 ensures buildings will not be constructed on active earthquake faults.  State Senator Ted Lieu says his legislation closes a loophole in the law that only restricts construction on zoned faults.  

"...but develops in cities were able to completely ignore the unzoned but mapped earthquake faults and build buildings over them.  My law simply says you must treated the unzoned faults like the zoned ones," Lieu said.

He added that 1,800 miles of faults across California are not yet zoned, and he fears they could be the site of buildings vulnerable to earthquakes.
