Blisniuk and her team calculated the Mission Creek strand has a slip rate of 21.6 millimeters per year. 3.1 magnitude earthquake hits near Antioch The reports team was surprised by the extent of the fire damage from the quake, Jones says, but it could be worse if the Santa Ana winds are blowing when the event happens. Many of these distribution lines for water are near sewer lines, which would also be broken, so now you have a situation where contaminants are potentially getting into the water supply. Advertising Notice Let us know if you have suggestions to improve this article (requires login). Strain builds up for one or two hundred years along that boundary, and then finally that strain becomes so great that the fault can't take it anymore. There's a sense that if it's modern, code-designed, it's earthquake-proof and everything should be great, but that's not the reality. Ten years ago, Kim Blisniuk was hiking along the San Andreas fault in the Coachella Valley desert when she looked up and saw something spectacular in the rocks: channels running along the canyon that would later challenge scientists understanding of how quake damage in Southern California might shake out. On average, Southern California has seen big quakes every 110 to 140 years, based on records of past earthquakes and studies of earthquake faults.

Second, if the San Andreas fault was continuous offshore, a tsunami probably would not have been recorded. More than 38 million people live near the fault, so a major earthquake would greatly affect large cities. All of these would be ruptured, and so we would be losing 60% of our water supply. The northern slice of the San Andreas has its own strain and slip, and its unlikely that a colossal earthquake down south will trigger any major damage in the northern part of the state, Blisniuk said. A rupture along that strand would potentially re-direct damage created by an earthquake along the southern part of the San Andreas, which scientists say could happen any time. There are a lot of little things we can do. San Andreas Fault: What Will Happen If It Breaks? When Will the Next Vidale: People have this idea of running out of bed, out of their buildings, and that's a terrible idea, because a lot of what we see in earthquakes is people with broken legs and people who've run through glass. The U.S. Geological Survey calculated those quakes as having violent shaking, or an intensity of 9 on a 10-point scale. The task force reported that building codes could be changed to require retrofitting of older structures so that they would withstand powerful shaking. It's every few hundred years. Vidale: To trigger a tsunami, it takes an earthquake that moves the ocean floor, and most of the San Andreas is on land, so there would be a little bit of waves generated from a San Andreas earthquake, but nothing that would be dangerous.
