Figure 3. Comparison of time-magnitude distributions of the 2005 and 2021 datasets and the Anza 2016 mainshock/aftershock sequence. To us, the behavior of the 2021 data looks most similar to the 2016 sequence, exhibiting a paucity of events over magnitude-3. This differs from the 2005 behavior that contains many approximately magnitude-3 earthquakes, which is more typical of an earthquake swarm.
