As the anniversary approaches for the California Northridge Earthquake there have been additional concerns of how prepared California is to handle another quake.

Last Wednesday, a 4.4 magnitude earthquake centered in San Bernardino jolted a wide area of Southern California, according to NBC Los Angeles.

The epicenter of the earthquake was three miles north of Fontana about 50 miles east of downtown Los Angeles. Although the quake was centered miles from LA the aftershocks were felt all across the state.  ABC reported multiple aftershocks  from West Covina, Anaheim and even Santa Monica.

According to MyFoxLA, California’s Early Earthquake Warning Coordinator Doug Given says that California is behind in installing earthquake sensors to due a growing cost to input them across various areas within the state. The estimated cost is $80 million, a fraction of the state budget, which would allow a warning signal to go out across the state buying anywhere from a few seconds to a few minutes of time for residents to respond and become more prepared.

Last year Governor Brown signed a bill mandating that an early warning system be put in place, but there hasn’t been much discussion of the bill or where the funds would come from. As many California residents recall the devastating 1993 earthquake, many have prepared on their own for California’s next big quake.

The Northridge quake resulted in $20 million in damages with 82,000 residential and commercial buildings being impacted. A key part in not reliving this history is the state’s preparation in structuring new homes and complexes with earthquake safety in mind. Although plans were put in place to improve buildings, many contractors aren’t seeing the results that they’d like to. According to Southern California Public Radio, California is still in a rebuilding phase and money needs to be contributed to improve our earthquake readiness.

Only time will tell how successful we’ve been in learning from the past.
