The system detects earthquakes as low as magnitude 3.5. A large earthquake is a much less likely scenario, the agency said. For every earthquake, there is a region near the epicenter where alerts will not arrive before shaking begins because the ShakeAlert system needs time to detect the earthquake, issue an alert, and for USGS partners to distribute the alert. The good news is, we're not likely to see a magnitude 10. Im a little bit surprised we found this many, Meng said of the newly identified supershear quakes, all of which took place along underwater fault lines beyond the reach of most land-based monitors.
