A major earthquake in California is likely to knock out many communications services, including cellphones, for days or weeks, a USGS study finds.
Seismologist Lucy Jones, journalists Rong-Gong Lin and Patt Morrison of the L.A. Times, and journalists Jacob Margolis and Austin Cross of KPCC/LAist discuss earthquake safety and resilience in California. Here are five things to remember when preparing for the Big One.
In a hypothetical quake on the Hayward fault, between 720,000 and 1.45 million residents are at risk of being displaced from their homes, the USGS said.are a major risk. In places like Oakland, Berkeley, Hayward and Alameda, there are many so-called soft-story apartment buildings, with flimsy first floors housing carports that can collapse in an earthquake, as well as old, vulnerable brick and brittle concrete residential buildings.
There could be a wave of mortgage defaults, a deterioration of mental health and persistent blighted property, which could be exacerbated by years of significant aftershocks that could strike farther away from the fault, including underneath the Silicon Valley cities of Palo Alto, Cupertino and Sunnyvale.
Old single-family houses and apartment buildings need to be seismically strengthened; so does infrastructure, such as systems that send water, electricity, fuel and communications to homes and businesses, the report suggested. More new housing, built to modern-day standards, needs to be made available before the shaking begins, and governments need to plan for a long-term recovery with a plan to finance it.
A majority of U.S. residents live in wireless-only households, said David Witkowski, a co-author of the USGS report. Nationwide, 57% of people no longer have wired phones in their homes; that figure exceeds 76% among people in their late 20s and early 30s.
