A new model found to predict earthquake propagation speed (IMAGE)
Caption
Left : an earthquake rupture with oblique slip. The surface cutting through the Earth's crust is a fault. The oblique offset of the small block indicates the direction of slip. The colors on the fault plane show the amount of fault slip at five successive times, generated by a computer simulation. The slip is limited in depth and sweeps along the fault at a speed called the rupture speed.
Right : the rupture speeds that large oblique-slip earthquakes can achieve.
This diagram shows how the steady rupture speeds of large earthquakes in the new model by Weng and Ampuero (2020) depend on the slip-obliqueness angle and on the strength of the fault.
