The seismicity, as measured by the b-value, is comparable before and after wastewater injection.
Earthquakes are over 100 times more frequent in Oklahoma after widespread wastewater injection began.
Oklahoma has a smaller b-value than the Parkfield region, so the Parkfield region has more earthquakes.
Oklahoma has a b-value smaller than the Parkfield region, so a randomly selected earthquake above magnitude 3 in Oklahoma more likely than not has a smaller magnitude than one above magnitude 3 randomly selected from the Parkfield region.
