title: 1969 Santa Rosa earthquakes text: 1969 Santa Rosa earthquakes At 04:56 and 06:19 UTC on October 2, 1969 (21:56 and 23:19 PDT October 1), a pair of earthquakes of magnitude 5.6 and 5.7, respectively, struck the city of Santa Rosa, California, killing one person and damaging buildings. The maximum felt intensity for the two events was VII ("Very strong") and VIII ("Severe") respectively on the Mercalli intensity scale. The $8.35 million cost of the earthquakes went mostly to replace buildings damaged beyond repair. There were at least 200 aftershocks after the initial pair of earthquakes. At the time they were the largest earthquakes to affect title: Eureka, California text: largest recent earthquake since the April 25–26, 1992 sequence. It was followed on February 4, 2010, by a magnitude 5.9 earthquake which struck about northwest of the community of Petrolia and nearly west of Eureka. The shaking was felt within a radius, as far north as southern Oregon and as far south as Sonoma County. The largest recorded in the area was the 7.2 event on November 8, 1980. The larger earthquakes can pose a tsunami threat to coastal areas. Eureka is located at (40.790022, −124.162752). According to the United States Census Bureau, the city has a total area of title: 1980 Eureka earthquake text: 1980 Eureka earthquake The 1980 Eureka earthquake (also known as the Gorda Basin earthquake) occurred on November 8 at along the northern coastal area of California in the United States. With a moment magnitude of 7.3 and a maximum Mercalli intensity of VII ("Very strong"), this strike-slip earthquake was the largest to occur in California in 28 years. Although damage was considered light, several loss estimates equaled or exceeded $2 million, and six injuries resulted when two vehicles came down with the partial collapse of a highway overpass on US 101 in Fields Landing. The north coast of California experiences title: 2003 San Simeon earthquake text: 2003 San Simeon earthquake The 2003 San Simeon earthquake struck at 11:15 PST (19:15 UTC) on December 22 on the Central Coast of California, about northeast of San Simeon. Probably centered in the Oceanic fault zone within the Santa Lucia Mountains, it was caused by thrust faulting and the rupture propagated southeast from the hypocenter for 12 miles (19 km). The most violent ground movement was within 50 miles of the epicenter, though the earthquake was felt as far away as Los Angeles. With a moment magnitude of 6.6, it was the most destructive earthquake to hit the United States title: 1857 Fort Tejon earthquake text: 1857 Fort Tejon earthquake The 1857 Fort Tejon earthquake occurred at about 8:20 am (Pacific time) on January 9 in central and Southern California. One of the largest recorded earthquakes in the United States, with an estimated moment magnitude of 7.9, it ruptured the southern part of the San Andreas Fault for a length of about 225 miles (350 kilometers), between Parkfield and Wrightwood. The earthquake was felt throughout much of California, as far north as the city of Marysville and as far south as the mouth of the Colorado River at the Gulf of California in Mexico, and as
