Many users could see the alerts as false alarms if the quake never developed into a more powerful tremor. February 2022. published 27 October 21. "You're moving and the wood is cracking around you," she says. But predictions for low levels of shaking could be sent out quickly, while the earthquake was still at a relatively low magnitude. By modeling the physics of the subduction zone and the movement of fluids along the fault, the researchers found that the rapid change was caused by a release of built-up strainthe beginning of a slow-motion earthquake.
