Just before dawn on 28 June last year, the Mojave Desert 200 km east of Los Angeles was struck by a magnitude‐7.3 earthquake. Although the Landers earthquake, named for the small town nearest the epicenter, was stronger than the earthquake that had rocked San Francisco three years earlier, it attracted little public attention, because the region is so sparsely populated. But it made seismological history. The dense and extensive network of seismographic stations built up in the Far West during the 1980s has provided convincing evidence that the Landers quake triggered secondary tremors as far away as Yellowstone National Park, 1250 km to the northeast.
