The Fault Line And The Dams
The earthquakes that rocked Kern County in early July are a potent reminder of the East Bay’s own seismic risk. Last year, the U.S. Geological Survey imagined what could happen during a 7.0 quake on the Hayward Fault, which stretches 74 miles from north San Pablo Bay past San Jose. This so-called “HayWired Scenario” envisioned 800 people dying, 18,000 more being injured, and widespread damage occurring to property and infrastructure. The study also predicted that the surface of the earth would rupture in places “where the fault is currently creeping.” Some fault lines, which mark the edge of plates in the earth’s crust, only move during earthquakes.
