In both locations, these long-duration quakes are also accompanied by a slew of tiny quakes known as tremors. The strength of an earthquake matters, and so does what happens after the shaking stops. Mexico and Japan adopted earthquake early-warning systems years ago, but they are still imperfect (both have issued false alarms). The USGS will issue ShakeAlertMessages to facilitate the delivery of public alerts of potentially damaging earthquakes and provide warning parameter data to government agencies and private users on a region-by-region basis, as soon as the ShakeAlert system, its products, and its parametric data meet minimum quality and reliability standards in those geographic regions.
