A seismologist from Berkeley said on KCBS that the ShakeAlert system worked in the case of this earthquake. So many people in the area were warned. I heard this on Audacy from the Philadelphia area.

ShakeAlert and similar systems are awesome, but not exactly what most folks mean by a prediction, FWIW. They're meant for warnings of seconds, but not for things on the scale of minutes or hours or days. Not to take away from ShakeAlert in any way though! Just clarifying that in terms of another comment I made about earthquake precursor signals. ShakeAlert and similar aren't about precursors, but instead are about "the earthquake has happened, let's tell folks before the damaging surface waves reach them".

  Still better than a sharp stick in the eye!

  I mean, warnings of seconds is the best we can do right now but the goal is prediction. it's not a lot but it's enough to stop surgeries and trains.
