But San Francisco wasn't the only place to get hit… In San Jose, 8000 people were homeless. “ The quake hit San Francisco on Wednesday, April 18, at precisely 12 minutes past five o'clock in the morning. Each will have a different effect on landforms. These "reassembled continents" have matching fossil floras and faunas. In addition, if one "plays this tape backwards" the continents, which ride on the tectonic plates, reassemble along their edges with near perfect fits. An interlocking body of evidence, from many locations and times, give paleomagnetists confidence that these data are revealing a correct picture of the Earth's plate motions. Older "paleomagnetic" data exists but the picture is less continuous. By sampling these rocks and using radiometric dating techniques it has been possible to reconstruct the history of the Earth's magnetic field for the last 160 million years or so. The slowly moving plates act as a kind of a recorder leaving information about the strength and direction of past magnetic fields. When the tectonic plates form along the oceanic ridges, the magnetic field that exists is imprinted on the rock as they cool. The Earth's magnetic field is slowly changing and appears to have been changing throughout its existence. What is so strange about coal being discovered in Antartica?
