The vast majority were destroyed by raging fires after the tremors ruptured gas and water pipes. In Cascadia and Nankai, the slow quakes strike with remarkable regularity, stirring every 14 months or so in Cascadia and every three to six months in Nankai. For example, isolating utilities before shaking starts can reduce the number of fire initiations. Supershear earthquakes are more likely to happen along long, mature faults like the San Andreas, where many years of activity have ground away a lot of the twists and bumps that might slow down an earthquakes energy. ShakeAlert-powered alerts delivered by alert distribution partners could give enough time to slow trains and taxiing planes, to prevent cars from entering bridges and tunnels, to move away from dangerous machines or chemicals in work environments and to take cover under a desk, or to automatically shut down and isolate industrial systems.
