And who could ever forget the great 7.2 Mexicali quake 13 years ago ?

The 2020 Westmorland, California Earthquake Swarm as
Aftershocks of a Slow Slip Event Sustained by Fluid Flow

Static stress triggering analysis using Coulomb stress
and statistics of interevent times suggest that 45%–65%
of seismicity was driven by the slow slip event, 10%–35%
by inter-earthquake interactions, and 10%–30% by fluids.
Our model also provides constraints on the friction
parameter and the pore pressure and suggests that this
swarm behaved like an aftershock sequence but with the
mainshock replaced by the slow slip event.
