Experts say that once a major earthquake occurs in the area, there could be another major earthquake. A swarm of more than 40 earthquakes in 24 hours is causing ... a fault is a fracture in the earth, on which the blocks adjoining the fault on either side are displaced relative to each other by slip along the fault whilst we are mainly aware of faults in the earth's crust, deep-seated faults affect the mantel down to depths of 750km and which are concerned in the origin of deep-focus earthquakes. Since Australia sits on top of a very stable because geologically old continental landmass in the middle of a tectonic plate (the Australian Plate) with no major active faults, it has far fewer quakes than areas near plate boundaries or major fault lines. Faults | U.S. Geological Survey But while a quake is unlikely in our lifetime . Faults are most common around the edges of tectonic plates but can occur anywhere. The last big quake near Los Angeles, a magnitude 7.9, struck Fort Tejon in 1857. Victoria earthquake likely caused by NZ tectonic pressure ... Fault movements through earthquakes redistribute stress in the crust around the epicentre and consequently affect the future earthquake activity in the region.
