Hi Canie. To date I haven’t been able to find anything that says one has been done. However there are those who have the ability to do it.

It seems that the two following individuals have perfected a way in which other areas can be checked after a major quake nearby…Take Care…Don in creepy town

The two largest quakes to hit Southern California in the last 10 years may have been connected, according to Andrew Freed, a geophysicist at the Carnegie Institution in Washington, D.C., and Jian Lin, of Woods Hole Oceanographic Institution in Woods Hole, Mass. The two researchers studied the 1992 Landers earthquake and the 1999 Hector Mine earthquake, which occurred on neighboring faults about 12 miles from each other, northeast of Los Angeles. The first had a magnitude of 7.3 on the Richter scale, and the second a magnitude of 7.1.

In their Nature report, Freed and Lin use a stress model to illustrate the effects of Landers on the Hector Mine quake, and also the predicted stress effect on other faults in Southern California, including the San Andreas fault. To expand this tool for use in all earthquakes, however, more information is needed. Precise data on the viscosities of the upper and lower mantle are needed, according to the study. Research is already underway to gather this data.
