If the 7.0-magnitude earthquake 30 miles off the northern California shore was not a wake-up call for residents of San Luis Obispo, are they waiting for the one that could possibly strike 30 yards off the coast of San Luis Obispo? Seismologists have long warned that an overdue “Big One” (7.8 magnitude or higher), which California has not experienced since 1906, could happen at any point.
Since the initial application for Diablo Canyon Power Plant which was written 60 years ago—much seismic and geographic information has come to light. Notably there are four earthquake faults running under and near Diablo, the closest of which is a mere 1,000 yards away (the Shoreline fault). The Nuclear Regulatory Commission has failed to give any serious credence to multiple verifiable reports on the seismic danger. The NRC is in the process of considering an application by PG&E to continue operations of the plant for an additional 20 years.
The recent earthquake also triggered a tsunami warning, and residents were advised to relocate “to higher ground.” Should a tsunami warning also be issued in San Luis Obispo after an earthquake, the existing evacuation routes would fail. Highway 101 backs up on an almost daily basis with either an accident, a fire, commuter traffic, and other events. Residents would not be able to leave the county. The SLO Emergency Evacuation Plan was devised decades ago before the population of San Luis Obispo County increased.
Any decision to extend the operation of Diablo Canyon Power Plant, whose nuclear waste is stored onsite, is totally unacceptable and dangerous. A large swath of the Central Coast could become uninhabitable.

Yes, let’s all focus on this like every time one hits anywhere for the next month. You clearly don’t know what building cofe diablo was built to, it is still much more elaborate than anything in the city currently. But sure, let’s write into the panic of the masses. This is scaremongering and sensationalist. Let’s see if it gets through the filters.
Yawn.
It’s not so much earthquakes we should be worried about. Rather, it’s DC’s ancient and obsolete control and instrumentation systems. They were designed in the ’70s and many devices are no longer in production. A wholesale upgrade needed to allow another 20 years operation will cost billions – it’s simply not cost effective and will cause already obscenely high rates to zoom even higher. Wind and solar are – by far – the cheapest utility-scale sources of energy. Even solar+battery is cheaper. Keep DC going for a few more years until sufficient solar+battery is built (which is being built at record rates) – then close it.
