During the seismically active period of the s, the BSZ produced close to half of the earthquakes recorded in California (Johnson and Hill, ; Hutton et al., ). However, for two decades following the Imperial Valley mainshock M and its aftershock sequence, the BSZ was much less active.

This feature is very unusual and an attempt has been made to determine if the recording is real or spurious. As the pumping station is a small heavily constructed bunker type of structure located on material of low shear wave velocity it was.

Some of the fault slip associated with the Imperial Valley earthquake occurred along other than the Imperial fault and the Brawley fault zone.
