It gets stored elastically, that is to say under pressure, in the upper crust of California’s bedrock, close to the fault. As a result of the large scale shaking, the Kern River was turned upstream and fish were . Taft) were populated back then, those locations would have 1857 fort tejon earthquake damage cost. . share: RoofMonkey. One geologist used evidences of past displacements on the fault, deformations of the crust, and distances between the two tectonic plates that move on opposite sides of the fault to propose a timetable for the future. earthquake scientists, or seismologists, think about great Were the Fort Tejon shock to happen today, the damage would easily run into billions of dollars, and the loss of life would be substantial. One occurred on the evening of the day of the main shock. The effects of the quake were quite dramatic, even frightening. The main area affected, however, while still large, is limited to a hundred-mile stretch of territory from 34 degrees north to 36.5 degrees north. From time to time the fault slips, the stored energy is released, and an earthquake occurs. The Fort Tejon earthquake, on January 9, 1857, registered at 7.9, making it one of the largest earthquakes ever recorded in the United States. 2, 2013 ©2013 by the University of Texas Press DOI: 1 .7560/IC48202.

The response of the two 18-story buildings hypothetically located at each of the 636 sites under 3-component shaking from all 60 events is computed using 3-D nonlinear time-history analysis. We use a new approached to the topic: the research skills of a historian in collaboration with a geologist to generate quantitative data on the nature and location of ground shaking associated with the earthquake. just as many aftershocks.
