Using high-speed photography and digital image correlation techniques, engineers show that friction along a faultline has a complex evolution during an earthquake that is dictated, in part, by slip ...

The dynamic rupture of earthquakes requires a strength loss from pre-slip, static friction to co-seismic, dynamic friction, and so major experimental effort has been devoted to determining fault ...
