In the spring of 1969 thousands of Californians, warned by soothsayers that earthquakes impended, shut themselves up in their houses or fled to what they thought safe places, where they waited for disaster through a day and a night like nineteenth-century Millerites gathered for the Second Coming. The earth did not tremble and gape—the San Andreas fault is fairly unresponsive to soothsaying—but the gullible demonstrated one important human truth: we can be more frightened by fictions and phantasms than by the things that should really scare us to death. These frightened people huddled in houses that were sunk in air murky with poisonous smog; they should have sniffed panic with every breath they drew. Those who fled rushed past endless overcrowded subdivisions down freeways that roared with cars bumper to bumper, four lanes each way, at seventy or eighty miles an hour; they should have heard apocalypse rumbling before and beside and behind. Above the murk and the traffic the firmament split with sonic booms. The passing roadside showed them the devastated redwood groves of Eureka and Arcata.
