They found a total of eight
such slow earthquakes in the same general vicinity.
Not exact matches
Shaking can depend significantly on factors
such as the depth of the
earthquake, the orientation of a fault, whether or not the fault break reaches the surface and whether the
earthquake rupture is relatively faster or
slower than average.
So far, scientists believe that larger
earthquakes are unlikely to occur following tremors or
earthquakes below a Richter scale of 2 that are caused by small vibrations or
slow fault movements
such as those observed in the area of Parkfield along the San Andreas Fault in California, USA.
Yet
slower, more continuous deformations —
such as those caused by Earth tides or by
slow earthquakes — are sometimes difficult to detect using large - scale techniques like GPS or seismic sensors.
1) tectonics —
earthquakes and
slow seismic events 2) erosion / sedimentation 3) isostatic rebound — response to a change in surface load (
such as the removal of an ice sheet or deposition or removal of sediment)
