And it's this rising pressure that is triggering new
motion along faults.
In the New Madrid seismic zone, the team found that
motion along the faults that are currently active has been occurring over many millions of years.
In Cascadia the slipping runs backward from the typical
motion along the fault.

In this study, Tramelli and her colleagues used the recorded waveforms from the 2012 Emilia seismic sequence to simulate a seismic sequence that triggered end - to - end earthquakes
along adjacent
fault patches, observing the affect of continuous ruptures on the resulting ground
motion and, consequently, its impact on critical structures, such as dams, power plants, hospitals and bridges.
«This
motion includes a component of slip
along the
fault and a component of normal
motion against the
fault that creates mountains.
Most typical earthquakes happen
along faults that have built - in brakes:
motion stops once the stress is relieved between the two chunks of earth that are trying to move past each other.
In the Fort Worth Basin,
along faults that are currently seismically active, there is no evidence of prior
motion over the past (approximately) 300 million years.
Their goal was to read all the vital signs of an earthquake — not just
fault motions but also the precise pressures, temperatures, strains, and chemical compositions of minerals in the nucleation zone,
along with an analysis of rocks and fluids extracted through the drill hole.
Creeping
faults exhibit slow, continuous
motion along them.
