A large earthquake is a much less likely scenario, the agency said. Their analysis found that in addition to five previously confirmed supershear earthquakes documented in their data set, a further seven also met the supershear criteria. This version of the ShakeAlert system is produces both point source and line source earthquake solutions, has added ground motion estimation products, and the number of false and missed events has been reduced. "A lot of people have suggested that these bigger, longer slow-slip events are possible," says Laura Wallace, a geophysicist at the University of Texas at Austin and GNS Science in New Zealand, who was not part of the study team.
