A series of moderate earthquakes rocked the California-Nevada border Wednesday, shaking residents in both states but producing no reports of major damage or injury. The first temblor, with a magnitude of 5.7, occurred at 12:22 a.m. near Hawthorne, Nev. It was followed by a second 5.7 quake and then more than 100 aftershocks. Light shaking was felt as far away as South Lake Tahoe, Fresno, Visalia and Merced.
