Sentences with phrase «largest magnitude of the earthquake»

«This is an important finding because some previously held theories propose that there is a relationship between the largest magnitude of the earthquake and the injected volume, but what we have found is that the maximum magnitude isn't what's being controlled by the volume, it's the earthquake rate,» says Atkinson, who notes that these two theories are slightly related because the more earthquakes that are induced provide more opportunities for a larger one to occur.
