In general, the more abrupt the onset of
slip during an earthquake, the more energetic the radiated high - frequency seismic waves.
The GPS records described in the Science Express paper show that within the zone that experienced the greatest amount of
slip during the earthquake — a region south of the sources of high - frequency waves and closer to Kathmandu — the onset of slip on the fault was actually very smooth.
Airborne UAVSAR mapping can allow a rapid response after an earthquake to determine what fault was the source and which parts of the fault
slipped during the earthquake.

The frictional resistance on a fault
during slip controls
earthquake dynamics.
This behavior provides an explanation for the huge shallow
slip that occurred
during the
earthquake.
The low resistance to
slip on the fault may help explain the large amount of
slip — an unprecedented 50 meters of displacement — that occurred
during the
earthquake, according to UC Santa Cruz researcher Patrick Fulton, who is first author of the paper focusing on the temperature measurements.
Using these same fault - zone materials, Ujiie et al. (p. 1211) performed high - velocity frictional experiments to determine the physical controls on the large
slip that occurred
during the
earthquake.
That will provide them with the resistance forces felt in the fault
during the
slip, filling in a blank in models of
earthquake dynamics.
An ultra-thin fault zone packed with slippery clay was behind the massive seismic
slip during the devastating Tohoku
earthquake of 2011 in Japan.
As
earthquakes occur
during the course of this project, the team is measuring the deformation at the time of the
earthquakes to determine the distribution of
slip on the faults, and then monitoring longer - term motions after the
earthquakes to learn more about fault zone properties.
A comprehensive analysis of 101 major
earthquakes around the Pacific ring of fire between 1990 and 2016 shows that most of the aftershock activity occurred on the margins of the areas where the faults
slipped a lot
during the main
earthquakes.
However,
during deglaciation, the faults experience accelerated
slip and
earthquakes are triggered (see Post-glacial rebound).
