were is the epicenter of 1906 S.F. earthquake?

The San Andreas fault ruptured 430 km from San Juan Bautista to the Cape Mendocino triple junction. The motion was predominately right-lateral strike-slip, with a peak displacement of 6 meters near Olema, Ca. which is located 37 miles NW of San Francisco.

back in the early 19th century a major earthquake occurred that was centered in new madrid, missouri. the entire middle section of the US is considered to be in the zone.

"magnitude" is at which the scale the earthquake has devastated the region.

the New Madrid fault is in the southeast part of the state, near Memphis.  it doesnt get earthquakes often, especially not big ones.  they just had a 2.7 a couple days ago, but you can barely feel that.\nthere was a really big one back in the 1800s.

Indonesia is huge compared to Singapore. Pick a Sinapore-sized part of Indonesia at random, and see if it had any earthquakes.

the beginning of an earthquake are foreshocks. these foreshocks have P-waves, s-waves and surface waves attached to it.

There are earthquakes all the time.  Do you mean a destructive one?  That would be the quake that interrupted a game during the 1989 World Series when the Giants were playing at home.  Do you mean one some people just barely felt or noticed?  Earlier this month.  Do you mean one detected only by seismograph?  Probably within the last fifteen minutes.\nThe San Andreas fault runs right through San Francisco Bay, and there are plenty of other active faults in the area.

Did you mean 1957?\n\nMarch 22, 1957 \nThe worst earthquake since 1906 struck at 11:45 this morning, and registered 5.3 on the Richter scale. The main shock had been preceded by at least six smaller quakes throughout the morning. The quake started some fires, including a blaze caused by a spill in the chemistry lab at old Lowell High School, according to Lowell student Frederick F. Postel. Fires connected to the earthquake broke out, but that was denied by the Fire Chief, possibly for political reasons. The tremor was preceded by a magnitude 3 shock at 8:38 a.m., and a magnitude 3.75 quake at 10:48 a.m. There were no lives lost. The quake was centered in the Westlake District of Daly City where many water heaters were ripped from their moorings and much plaster was damaged. \n\nThree-alarm fire at Mission and Duboce shortly after the earthquake in buildings scheduled to be torn down for the new Central Freeway. Fire Chief William F. Murray said the fire was not earthquake caused, but communications were jammed because of the tremor. Five firemen were injured. \n\nMany buildings suffered damage in the earthquake. KPIX at 2655 Van Ness suffered broken windows as did the Palace Hotel. The top floor of St. Anne's School at 13th and Irving was badly damaged, but the children were safe. The McCreery Branch of the library, on Sixteenth near Market was so badly damaged that it would be razed. The Presidio, Sunset and Richmond branch libraries were also damaged. A water main broke at City Hall and flooded Mole Hall under construction at Civic Center. Masonry fell from California Hall at Turk and Polk streets, and Central Emergency Hospital at 50 Ivy St. reported at least 50 people were treated for injuries. There was much glass and plaster damage at the ParkMerced Apartments, and the road at Lake Merced collapsed. Sheridan Elementary, Longfellow, Mission High and Park Presidio Junior High were closed because of earthquake damage. \n\nEnglish comedianne Gracie Fields said, "We were on the 16th floor of a hotel when the earthquake it. We were picked up like a wedding cake, shaken and then dropped to the floor again. It was very exciting." Plaster fell in the corridors at the Hall of Justice on Kearny St., but there were no injuries in the building. \n\nThe Municipal Organ, largest west of Chicago, had broken pipes and a dislodged harp attachment which would cost $300 to repair, according to James T. Graham, auditorium supervisor. At Golden Gate Park, the Portals of the Past, remnants of the Nob Hill home of A.N. Towne from 1906, were damaged by the earthquake when one column fell. \n\nMarch 23, 1957 \nFire broke out at the Twin Peaks Hotel, 2160 Market St., shortly after the 12:14 a.m. aftershock. Two policemen were felled by smoke while rescuing 50 people from the hotel and adjoining buildings. The arson squad could find no connection between the earthquake aftershock and the fire. \n\nSpeaking from his laboratory in Pasadena, Dr. Charles Richter said, This is not a prediction; it is only another way of saying that in California we must learn to live with the constant possibility of a serious earthquake." \n\nAdmiral A.G. Cook, the city's civil defense director, said a minimum of 70,000 homes had been damaged in the Bay Area by the earthquake. \n\nMarch 24, 1957 \nFire at the Crown Cork and Seal Co. on Bayshore Blvd. today was caused by boxes that fell in the earthquake and knocked a thermostat out of commission. That allowed an overhead gas heater to overheat and start the fire. It did $2500 damage. \n\nMarch 26, 1957 \nFire Chief Murray said none of the fires that occurred around the time of the earthquake were connected with the tremor. \n\nApril 1, 1957 \nCoast Highway 1 was reopened at Thornton Bluffs after earthquake- caused landslides were cleared away. \n\nApril 7, 1957 \nTwo mild aftershocks of the March 23 earthquake were felt. \n\nApril 9, 1957 \nAn earthquake-weakened water main broke at Haight and Buc

Fort Tejon, California \n1857 01 09 16:24 UTC \nMagnitude 7.9\n\nThe magnitude of the Fort Tejon and San Fransisco earthquake are estimated to have been very similiar. Since you asked for the largest SOUTHERN California Earthquake though, the Fort Tejon one would be the corrrect answer.

(m)\n\nThe Twentieth Century's Largest Earthquake\n\n\nThree of the ten largest earthquakes of the twentieth century occurred in Alaska, striking in 1957, 1964, and 1965. The strongest of these (magnitude: 9.2) took place on Good Friday in 1964, hitting 80 miles east of Anchorage. The biggest earthquake of the century struck Chile on May 22, 1960. Its magnitude, the highest ever recorded, was 9.5. \n\nThe deadliest earthquake of all time is believed to have occurred on Jan. 24, 1556, in Shaanxi (Shensi) Province, China — 830,000 were killed.\n\n\nTsunami\n\n\nThe Alaskan Good Friday earthquake was followed by tsunami, or tidal waves, that reached 50 feet high and traveled a phenomenal 8,445 miles at 450 miles per hour. Tsunami is a Japanese term (tsu, port; nami, waves) presumably referring to the rising height of tsunami as they approach shore. \n\nBreaking on land, these tremendous waves can cause enormous destruction. The deadliest tsunami ever occurred on Dec, 26, 2004, killing more than 225,000 people and leaving millions homeless. \n\nIn addition to earthquakes, volcanoes can cause tsunami—after the eruption of Krakatoa on August 27, 1883, more than 36,000 people were killed by the tsunami alone.

The initial shock that lasted 4 minutes knocked out seismographs at the central weather bureau office in Tokyo so that a seismograph in Tokyo Imperial University made the only record of the series of more than 1,700 earthquakes that struck the Tokyo area over the following three days.? The maximum magnitudes of the earthquake measured between 7.9 and 8.3 on the Richter scale, with the epicenter located 50 miles southeast of Tokyo in Sagami Bay.

I actually saw a documentary on this, on the channel "Discovery Civilizations".\n\nBasically, it said the whole area is tectonically unstable and laced with pockets of underground gas.  There was an earthquake, that resulted in liquefaction of the sands, and the entire cities slid right into the sea.  The fires were the result of friction lighting the gas pockets on fire.   \n\nIt would have been horrifying to behold.
